1.0 配置分页
创建MybatisPlusConfig类(创建路径com/vueblog/config)
package com.vueblog.config;
import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@EnableTransactionManagement
@MapperScan("com.markerhub.mapper")
public class MybatisPlusConfig {
@Bean
public PaginationInterceptor paginationInterceptor() {
PaginationInterceptor paginationInterceptor = new PaginationInterceptor();
return paginationInterceptor;
}
}
2.0 生成代码
创建CodeGenerator(在com.vueblog包下面)
**修改对应的数据库:账号密码、数据库名、包配置(ctrl+f可找到对应位置) **
然后运行输入俩表 ,号隔开是多表
package com.vueblog;
import com.baomidou.mybatisplus.core.exceptions.MybatisPlusException;

import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;
// 演示例子，执行 main 方法控制台输入模块表名回车自动生成对应项目目录中
public class CodeGenerator {
/**
*

*/
public static String scanner(String tip) {
Scanner scanner = new Scanner(System.in);
StringBuilder help = new StringBuilder();
help.append("请输入" + tip + "：");
System.out.println(help.toString());
if (scanner.hasNext()) {
String ipt = scanner.next();
if (StringUtils.isNotEmpty(ipt)) {
return ipt;
}
}
throw new MybatisPlusException("请输入正确的" + tip + "！");
}
public static void main(String[] args) {
// 代码生成器
AutoGenerator mpg = new AutoGenerator();
// 全局配置
GlobalConfig gc = new GlobalConfig();
String projectPath = System.getProperty("user.dir");
gc.setOutputDir(projectPath + "/src/main/java");
// gc.setOutputDir("D:\\test");
gc.setAuthor("anonymous");
gc.setOpen(false);
// gc.setSwagger2(true); 实体属性 Swagger2 注解
gc.setServiceName("%sService");
mpg.setGlobalConfig(gc);
// 数据源配置 数据库名 账号密码
DataSourceConfig dsc = new DataSourceConfig();
dsc.setUrl("jdbc:mysql://localhost:3306/vueblog?useUnicode=true&useSSL=false&characterEncoding=utf8&serverTimezone=UTC");
// dsc.setSchemaName("public");
dsc.setDriverName("com.mysql.cj.jdbc.Driver");
dsc.setUsername("root");
dsc.setPassword("123456");
mpg.setDataSource(dsc);
// 包配置
PackageConfig pc = new PackageConfig();
pc.setModuleName(null);
pc.setParent("com.vueblog");
mpg.setPackageInfo(pc);
// 自定义配置
InjectionConfig cfg = new InjectionConfig() {
@Override
public void initMap() {
// to do nothing
}
};
// 如果模板引擎是 freemarker
String templatePath = "/templates/mapper.xml.ftl";
// 如果模板引擎是 velocity
// String templatePath = "/templates/mapper.xml.vm";
// 自定义输出配置
List focList = new ArrayList<>();
// 自定义配置会被优先输出
focList.add(new FileOutConfig(templatePath) {
@Override
public String outputFile(TableInfo tableInfo) {
// 自定义输出文件名 ， 如果你 Entity 设置了前后缀、此处注意 xml 的名称会跟着发生变化！
return projectPath + "/src/main/resources/mapper/"
+ "/" + tableInfo.getEntityName() + "Mapper" + StringPool.DOT_XML;
}
});
cfg.setFileOutConfigList(focList);
mpg.setCfg(cfg);
// 配置模板
TemplateConfig templateConfig = new TemplateConfig();
templateConfig.setXml(null);
mpg.setTemplate(templateConfig);
// 策略配置
StrategyConfig strategy = new StrategyConfig();
strategy.setNaming(NamingStrategy.underline_to_camel);
strategy.setColumnNaming(NamingStrategy.underline_to_camel);
strategy.setEntityLombokModel(true);
strategy.setRestControllerStyle(true);
strategy.setInclude(scanner("表名，多个英文逗号分割").split(","));
strategy.setControllerMappingHyphenStyle(true);
strategy.setTablePrefix("m_");
mpg.setStrategy(strategy);
mpg.setTemplateEngine(new FreemarkerTemplateEngine());
mpg.execute();
}
}
效果如下:
1.0 UserController类(ctrl+R可全局搜索类)
package com.vueblog.controller;
import com.vueblog.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;

*/
@RestController
@RequestMapping("/user")
public class UserController {
@Autowired
private UserService userService;
@GetMapping("/index")
public Object index(){
return userService.getById(1);
}
}
2.0 运行项目 查看效果
这里我们用到了一个Result的类，这个用于我们的异步统一返回的结果封装。一般来说，结果里面有几个要素必要的
是否成功，可用code表示（如200表示成功，400表示异常）结果消息结果数据Result类(路径com.vueblog.common.lang;)
package com.vueblog.common.lang;
import lombok.Data;
import java.io.Serializable;
@Data
public class Result implements Serializable { //序列化
private int code; //200是正常 400表示异常
private String msg;
private Object data;//返回数据
//成功
public static Result succ( Object data){
return succ(200," *** 作成功",data);
}
//成功
public static Result succ(int code,String msg,Object data){
Result r = new Result();
r.setCode(code);
r.setMsg(msg);
r.setData(data);
return r;
}
//失败
public static Result fail(String msg){
return fail(400,msg,null);
}
//失败
public static Result fail(String msg,Object data){
return fail(400,msg,data);
}
//失败
public static Result fail(int code,String msg,Object data){
Result r = new Result();
r.setCode(code);

第三章 Shiro整合jwt逻辑分析
考虑到后面可能需要做集群、负载均衡等，所以就需要会话共享，而shiro的缓存和会话信息，我们一般考虑使用redis来存储这些数据，所以，我们不仅仅需要整合shiro，同时也需要整合redis。在开源的项目中，我们找到了一个starter可以快速整合shiro-redis，配置简单，这里也推荐大家使用。
而因为我们需要做的是前后端分离项目的骨架，所以一般我们会采用token或者jwt作为跨域身份验证解决方案。所以整合shiro的过程中，我们需要引入jwt的身份验证过程。
那么我们就开始整合：
我们使用一个shiro-redis-spring-boot-starter的jar包，具体教程可以看官方文档：github.com/alexxiyang/…
导入shiro-redis的starter包：还有jwt的工具包，以及为了简化开发，引入hutool工具包。
pom.xml中导入:
<!-- shiro-redis -->
<dependency>
<groupId>org.crazycake</groupId>
<artifactId>shiro-redis-spring-boot-starter</artifactId>
<version>3.2.1</version>
</dependency>
<!-- hutool工具类 -->

if(user == null){
throw new UnknownAccountException("账户不存在");
}
if(user.getStatus() == -1){
throw new LockedAccountException("账户不存在");
}
AccountProfile profile = new AccountProfile();
BeanUtil.copyProperties(user,profile);//将user数据转移到profile
//用户信息 密钥token 用户名字
return new SimpleAuthenticationInfo(profile,jwtToken.getCredentials(),getName());
}
}
创建GlobalExceptionHandler 类
捕获全局异常
package com.vueblog.common.exception;
import com.vueblog.common.lang.Result;
import lombok.extern.slf4j.Slf4j;
import org.apache.shiro.ShiroException;
import org.springframework.http.HttpStatus;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseStatus;
import org.springframework.web.bind.annotation.RestControllerAdvice;
/**
* 日志输出
* 全局捕获异常
*/
@Slf4j
@RestControllerAdvice
public class GlobalExceptionHandler {
@ResponseStatus(HttpStatus.UNAUTHORIZED) //因为前后端分离 返回一个状态 一般是401 没有权限
@ExceptionHandler(value = ShiroException.class)//捕获运行时异常ShiroException是大部分异常的父类
public Result handler(ShiroException e){
log.error("运行时异常：-----------------{}",e);
return Result.fail(401,e.getMessage(),null);
}
@ResponseStatus(HttpStatus.BAD_REQUEST) //因为前后端分离 返回一个状态
@ExceptionHandler(value = RuntimeException.class)//捕获运行时异常
public Result handler(RuntimeException e){
log.error("运行时异常：-----------------{}",e);
return Result.fail(e.getMessage());
}
}
然而我们运行测试发现并没有拦截
因为我们没有进行登录拦截
@RequiresAuthentication//登录拦截注解
运行效果：
提示401登录异常
当我们表单数据提交的时候，前端的校验我们可以使用一些类似于jQuery Validate等js插件实现，而后端我们可以使用Hibernate validatior来做校验。
我们使用springboot框架作为基础，那么就已经自动集成了Hibernate validatior。(校验登录非空等等)
User实体类中
import javax.validation.constraints.Email;
import javax.validation.constraints.NotBlank;
....
@TableName("m_user")
public class User implements Serializable {
private static final long serialVersionUID = 1L;
@TableId(value = "id", type = IdType.AUTO)
private Long id;
@NotBlank(message = "昵称不能为空")
private String username;
@NotBlank(message = "邮箱不能为空")
@Email(message = "邮箱格式不正确")
private String email;
...
}
/**
*
*@RequestBody主要用来接收前端传递给后端的json字符串中的数据的(请求体中的数据的)；
* GET方式无请求体，所以使用@RequestBody接收数据时，
* 前端不能使用GET方式提交数据，
* 而是用POST方式进行提交。在后端的同一个接收方法里，
* @RequestBody与@RequestParam()可以同时使用，@RequestBody最多只能有一个，
* 而@RequestParam()可以有多个。
*
* @Validated注解用于检查user中填写的规则 如果不满足抛出异常
* 可在GlobalExceptionHandler中捕获此异常 进行自定义 返回数据信息
*/
@PostMapping("/save")
public Result save(@Validated @RequestBody User user){
return Result.succ(user);
}
启动postMan测试
如果postman没法启动
可以新建一个环境变量POSTMAN_DISABLE_GPU = true。
1.打开高级系统设置；
2.在“高级”选项卡中，单击“环境变量”；
3.添加一个新的系统变量；
4.关闭Postman并重新打开
定义捕获异常返回处理
在捕获异常 GlobalExceptionHandler类中修改如下：
/**
* 实体校验异常
* MethodArgumentNotValidException捕获实体校验异常
*/
@ResponseStatus(HttpStatus.BAD_REQUEST) //因为前后端分离 返回一个状态
@ExceptionHandler(value = MethodArgumentNotValidException.class)//捕获运行时异常
public Result handler(MethodArgumentNotValidException e){
log.error("实体捕获异常 ：-----------------{}",e);
BindingResult bindingException = e.getBindingResult();
//多个异常顺序抛出异常
ObjectError objectError = bindingException.getAllErrors().stream().findFirst().get();
return Result.fail(objectError.getDefaultMessage());
}
效果如下：(变得简短了)
输入正确的格式如下：
返回了我们需要的信息
因为是前后端分析，所以跨域问题是避免不了的，我们直接在后台进行全局跨域处理:
路径:com.vueblog.config
注意：此配置是配置到confroller的，在confroller之前是经过jwtFilter，所以在进行访问之前配置一下Filter的跨域问题
package com.vueblog.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
/**
* 解决跨域问题
*/
@Configuration
public class CorsConfig implements WebMvcConfigurer {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowedOrigins("*")
.allowedMethods("GET", "HEAD", "POST", "PUT", "DELETE", "OPTIONS")
.allowCredentials(true)
.maxAge(3600)
.allowedHeaders("*");
}
}
jwtFilter进行跨域处理:
路径:com.vueblog.shiro
/**
* 对跨域提供支持
* @param request
* @param response
* @return
* @throws Exception
*/
@Override
protected boolean preHandle(ServletRequest request, ServletResponse response) throws Exception {
HttpServletRequest httpServletRequest = WebUtils.toHttp(request);
HttpServletResponse httpServletResponse = WebUtils.toHttp(response);
httpServletResponse.setHeader("Access-control-Allow-Origin", httpServletRequest.getHeader("Origin"));
httpServletResponse.setHeader("Access-Control-Allow-Methods", "GET,POST,OPTIONS,PUT,DELETE");
httpServletResponse.setHeader("Access-Control-Allow-Headers", httpServletRequest.getHeader("Access-Control-Request-Headers"));
// 跨域时会首先发送一个OPTIONS请求,这里我们给OPTIONS请求直接返回正常状态
if (httpServletRequest.getMethod().equals(RequestMethod.OPTIONS.name())) {
httpServletResponse.setStatus(org.springframework.http.HttpStatus.OK.value());
return false;
}
return super.preHandle(request, response);
}
----基本框架已经搭建完成-----
第七章 登录接口开发 创建LoginDto路径： com.vueblog.common.dto
package com.vueblog.common.dto;
import lombok.Data;
import javax.validation.constraints.NotBlank;
import java.io.Serializable;
@Data
public class LoginDto implements Serializable {
@NotBlank(message = "用户名不能为空")
private String username;
@NotBlank(message = "密码不能为空")
private String password;
}
路径：com.vueblog.common.exception
/**
* 断言异常
* @param e
* @return
*/
@ResponseStatus(HttpStatus.BAD_REQUEST)
@ExceptionHandler(value = IllegalArgumentException.class)
public Result handler(IllegalArgumentException e){
log.error("Assert异常:------------------>{}",e);
return Result.fail(e.getMessage());
}
登录和退出逻辑
package com.vueblog.controller;
import cn.hutool.core.lang.Assert;
import cn.hutool.core.map.MapUtil;
import cn.hutool.crypto.SecureUtil;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.vueblog.common.dto.LoginDto;
import com.vueblog.common.lang.Result;
import com.vueblog.entity.User;
import com.vueblog.service.UserService;
import com.vueblog.util.JwtUtils;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authz.annotation.RequiresAuthentication;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.servlet.http.HttpServletResponse;
@RestController
public class AccountController {
@Autowired
UserService userService;
@Autowired
JwtUtils jwtUtils;
@RequestMapping("/login")
public Result login(@Validated @RequestBody LoginDto loginDto, HttpServletResponse response){
User user = userService.getOne(new QueryWrapper<User>().eq("username", loginDto.getUsername()));
Assert.notNull(user,"用户不存在");//断言拦截
//判断账号密码是否错误 因为是md5加密所以这里md5判断
if(!user.getPassword().equals(SecureUtil.md5(loginDto.getPassword()))){
//密码不同则抛出异常
return Result.fail("密码不正确");
}
String jwt = jwtUtils.generateToken(user.getId());
//将token 放在我们的header里面
response.setHeader("Authorization",jwt);
response.setHeader("Access-control-Expose-Headers","Authorization");
return Result.succ(MapUtil.builder()
.put("id",user.getId())
.put("username",user.getUsername())
.put("avatar",user.getAvatar())
.put("email",user.getEmail()).map()
);
}
//需要认证权限才能退出登录
@RequiresAuthentication
@RequestMapping("/logout")
public Result logout() {
//退出登录
SecurityUtils.getSubject().logout();
return null;
}
}
运行效果:
路径om.vueblog.util，可于判断等等
package com.vueblog.util;
import com.vueblog.shiro.AccountProfile;
import org.apache.shiro.SecurityUtils;
public class ShiroUtil {
public static AccountProfile getProfile(){

后端的一个骨架基本完成然后开始我们的前端开发
第九章 Vue前端页面开发 前言接下来，我们来完成vueblog前端的部分功能。可能会使用的到技术如下：
vue
element-ui
axios
mavon-editor
markdown-it
github-markdown-css
https://nodejs.org/zh-cn/
安装完成之后检查下版本信息：
# 安装淘宝npm
npm install -g cnpm --registry=https://registry.npm.taobao.org
# vue-cli 安装依赖包
cnpm install --g vue-cli
选中要建立的文件cmd打开
进入你的项目目录，创建一个基于 webpack 模板的新项目: vue init webpack 项目名
输入:
vue init webpack xx
全部enter即可
完成
运行项目
进入demo(项目)目录 运行
cd demo
npm run dev
浏览器打开

集成开发工具Visual Studio Code(VsCode)
VsCode的安装：https://code.visualstudio.com/
vscode前端常用插件推荐，搭建JQuery、Vue等开发环境
汉化插件：chinese
插件如何导入和一些推荐插件：
https://blog.csdn.net/jiandan1127/article/details/85957003/
ctrl+`(~键)打开终端
输入：
npm run dev
效果如下则成功：
https://element.eleme.cn/#/zh-CN/component/installation
ctrl+`(~键)打开终端输入安装命令
# 安装element-ui
cnpm install element-ui --save
然后我们打开项目src目录下的main.js，引入element-ui依赖。
import Element from 'element-ui'
import "element-ui/lib/theme-chalk/index.css"
Vue.use(Element)
import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import Demo from '@/views/Demo'
Vue.use(Router)
export default new Router({
routes: [
{
path: '/',
name: 'HelloWorld',
component: HelloWorld
}, {
path: '/Demo',
name: 'Demo',
component: Demo
}
]
})
src/views/demo
引入button按钮(官方直接复制)
<template>
<div class="Demo">
{{msg}}
<el-button type="primary">主要按钮</el-button>
</div>
</template>
<script>
export default{
name: "Demo",
data() {
return {
msg: "测试"
};
}
}
</script>
<div id="nav">
<router-link to="/demo">Demo页面</router-link>
</div>
autoOpenBrowser修改为true。
autoOpenBrowser:true
接下来，我们来安装axios（www.axios-js.com/），axios是一个基于 promise 的 HTTP 库，这样我们进行前后端对接的时候，使用这个工具可以提高我们的开发效率。
安装命令: cnpm install axios --save
import axios from 'axios'
//引用全局
Vue.prototype.$axios = axios
接下来，我们先定义好路由和页面，因为我们只是做一个简单的博客项目，页面比较少，所以我们可以直接先定义好，然后在慢慢开发，这样需要用到链接的地方我们就可以直接可以使用：
我们在views文件夹下定义几个页面：
BlogDetail.vue（博客详情页）
BlogEdit.vue（编辑博客）
Blogs.vue（博客列表）
Login.vue（登录页面）
可以配置插件:VueHelper(新建vue项目 最上方输入vuet按键tab可直接生成模板)
建立页面完成
注意:每个页面下方 里面只能有一个
路径：rountr/index.js
import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import Demo from '@/views/Demo'
import Login from '@/views/Login'
import Blogs from '@/views/Blogs'
import BlogEdit from '@/views/BlogEdit'
import BlogDetail from '@/views/BlogDetail'
Vue.use(Router)
export default new Router({
routes: [
{
path: '/',
name: 'Index',
redirect:{name : "Blogs"}
},
{
path: '/blogs',
name: 'Blogs',
component: Blogs
},{
path: '/Login',
name: 'Login',
component: Login
},{
path: '/blog/add',
name: 'BlogEdit',
component: BlogEdit
}, {
path: '/Demo',
name: 'Demo',
component: Demo
},{
path: '/blog/:blogid',
name: 'BlogDetail',
component: BlogDetail
} ,{
path: '/blog/:blogid/edit',
name: 'BlogEdit',
component: BlogEdit
}
]})
打开终端 npm run dev启动项目
可自行测试其他路由
测试完我们可以删掉App.vue中的测试和图片
Login.vie

在src包下面创建stroe文件夹
然后创建index.js
import Vue from 'vue'
import Vuex from 'vuex';
Vue.use(Vuex)
export default new Vuex.Store({
state: {
token:'',
userInfo:{}
},
mutations: {
},
actions: {
},
modules: {
}
})
然后我们给main.js中引入store
// 存储
import store from './store'
//在new Vue({}) 里面加入store
new Vue({
el: '#app',
router,
store ,
components: { App },
template: ''
})
// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
// 存储
import store from './store'
// 路由
import router from './router'
// 引入element-ui依赖
import Element from 'element-ui'
import "element-ui/lib/theme-chalk/index.css"
// 引入axios依赖
import axios from 'axios'
//引用全局
Vue.prototype.$axios = axios
Vue.use(Element)
Vue.config.productionTip = false
/* eslint-disable no-new */
new Vue({
el: '#app',
router,
store ,
components: { App },
template: ''
})
** npm run dev启动测试**
登录发起请求 (配置完善store)
配置完善store/index.js
在store下面的index.js添加*
mutationsx相当于java中实体类的set
getters相当于get
> userInfo可以存入会话的sessionStorage里面
> **sessionStorage中只能存字符串 不能存入对象所以我们存入序列化 jons串:**
> **sessionStorage.setItem("userInfo",JSON.stringify(userInfo))**
> 会话获取
> **sessionStorage.getInte(userInfo)**
> token可以存入浏览器的localStorage里面
> localStorage.setItem("token",token)
> token获取：
> localStorage.getItem("token")
import Vue from 'vue'
import Vuex from 'vuex'
Vue.use(Vuex)
export default new Vuex.Store({
//定义全局参数 其他页面可以直接获取state里面的内容
state: {
token: '', //方法一 localStorage.getItem("token")
//反序列化获取session会话中的 userInfo对象
userInfo:JSON.parse(sessionStorage.getItem("userInfo"))
},
mutations: {
//相当于实体类的set
SET_TOKEN:(state,token)=>{
state.token=token//将传入的token赋值 给state的token
//同时可以存入浏览器的localStorage里面
localStorage.setItem("token",token)
},
SET_USERINFO:(state,userInfo)=>{
state.userInfo=userInfo//将传入的tuserInfo赋值 给state的userInfo
//同时可以存入会话的sessionStorage里面 sessionStorage中只能存字符串 不能存入对象所以我们存入序列化 jons串
sessionStorage.setItem("userInfo",JSON.stringify(userInfo))
},
//删除token及userInfo
REMOVE_INFO:(state)=>{
state.token = '';
state.userInfo = {};
localStorage.setItem("token",'')
sessionStorage.setItem("userInfo",JSON.stringify(''))
}
},
getters: {
//相当于get
//配置一个getUser可以直接获取已经反序列化对象的一个userInfo
getUser: state=>{
return state.userInfo;
},getToken: state=>{
return state.token;
}
},
actions: {
},
modules: {

})
在Login.vue中添加
_this.$axios.post("http://localhost:8081/login", _this.ruleForm).then(res => {
console.log(res)
const jwt = res.headers['authorization'];
const userInfo = res.data.data
_this.$store.commit('SET_TOKEN', token)

可查看我们的信息已经存入浏览器中
配置axios拦截 src下面创建axios.js main.js中引入
// 引入自定义axios.js
import "./axios.js"
// 引入axios依赖
import axios from 'axios'
// 引入element-ui依赖
import Element from 'element-ui'
import store from './store';
// 引入路由
import router from './router'
var s=window.location.toString();
var s1=s.substr(7,s.length);
var s2=s1.indexOf("/");
s=s.substr(0,8+s2);
var a = "http://localhost:8081/";//获取连接前缀相当于 http://localhost:8081/
//配置默认前缀
axios.defaults.baseURL= a
//配置前置拦截
axios.interceptors.request.use(config => {
return config
})
//配置后置拦截
axios.interceptors.response.use(response=>{
let res = response.data;
if(res.code == 200){
return response
}else{
Element.Message.error(" *** 作错了哦",{duration : 2*1000})
//返回一个异常提示就不会继续往下走了 不+的话 res=>的里面 还是会继续走的
return Promise.reject(response.data.msg)
}
// 捕获并处理后台异常信息
},error=>{
// 使得异常信息更加友好
console.log(error)
if (error.response.data) { //data不为空时
error.message = error.response.data.msg
console.log("-------------------------")
console.log(error.message)
console.log("-------------------------")
}
if(error.response.status == 401){
store.commit('REMOVE_INFO')//清空token userinfo
router.push("/login") //跳转登录页面
}
Element.Message.error(error.message)
return Promise.reject(error)
}
)
打开AccountController
要先打开在logout方法里面返回一个Result 不然会报错
如果报错了这个需要先安装redis并且启动

运行效果
编辑：
博客详情和编辑按钮的权限博客详情中需要回显博客信息，然后有个问题就是，后端传过来的是博客内容是markdown格式的内容，我们需要进行渲染然后显示出来，这里我们使用一个插件markdown-it，用于解析md文档，然后导入github-markdown-c，所谓md的样式。
# 用于解析md文档
cnpm install markdown-it --save
# md样式
cnpm install github-markdown-css
然后就可以在需要渲染的地方使用：
views\BlogDetail.vue<template>
<div>
<Header></Header>
<div class="blog">
<h2>{{blog.title}}</h2>
<el-link icon="el-icon-edit" v-if="ownblog">
<router-link :to="{name:'BlogEdit',params:{blogid:blog.id}}">
编辑
</router-link>
</el-link>
<el-divider></el-divider>
<div class="markdown-body" v-html="blog.content"></div>
</div>
</div>
</template>
<script>
import 'github-markdown-css'
import Header from "../components/Header";
export default {
name: "BlogDetail",
components: { Header },
data () {
return {
blog: {
id: '',
title: '',
content: '',
description: ''
},
ownblog: false
}
},
created () {
//获取动态路由的 blogid
const blogId = this.$route.params.blogid
const _this = this
if (blogId) {
this.$axios.get("/blog/" + blogId).then(res => {
const blog = res.data.data
_this.blog.id = blog.id
_this.blog.title = blog.title
_this.blog.description = blog.description
//MardownIt 渲染
var MardownIt = require("markdown-it")
var md = new MardownIt();
var result = md.render(blog.content)
_this.blog.content = result
//查看是否是登录人 是则可以编辑
_this.ownBlog = (blog.userId === _this.$store.getters.getUser.id)
})
}
}
}
</script>
<style scoped>
.blog {
margin-top: 10px;
box-shadow: 0 2px 12px 0 rgba(0, 0, 0, 0.1);
width: 100%;
min-height: 700px;
padding: 10px;
}
</style>
页面已经开发完毕之后，我们来控制一下哪些页面是需要登录之后才能跳转的，如果未登录访问就直接重定向到登录页面，因此我们在src目录下定义一个js文件：
//配置一个路由前置拦截 rounter是路由
src\permission.jsimport router from "./router";
// 路由判断登录 根据路由配置文件的参数
router.beforeEach((to, from, next) => {
if (to.matched.some(record => record.meta.requireAuth)) { // 判断该路由是否需要登录权限
const token = localStorage.getItem("token")
console.log("------------" + token)
if (token) { // 判断当前的token是否存在 ； 登录存入的token
if (to.path === '/login') {
} else {
next()
}
} else {
next({
path: '/login'
})
}
} else {
next()
}
})
通过之前我们再定义页面路由时候的的meta信息，指定requireAuth: true，需要登录才能访问，因此这里我们在每次路由之前（router.beforeEach）判断token的状态，觉得是否需要跳转到登录页面。
src/rouer/index.js添加：
meta: {
requireAuth: true
}
{
path: '/blog/add', // 注意放在 path: '/blog/:blogId'之前
name: 'BlogAdd',
meta: {
requireAuth: true
},
component: BlogEdit
},{
path: '/blog/:blogid/edit',
name: 'BlogEdit',
component: BlogEdit,
meta: {
requireAuth: true
}
import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import Demo from '@/views/Demo'
import Login from '@/views/Login'
import Blogs from '@/views/Blogs'
import BlogEdit from '@/views/BlogEdit'
import BlogDetail from '@/views/BlogDetail'
Vue.use(Router)
export default new Router({
routes: [
{
path: '/',
name: 'Index',
redirect:{name : "Blogs"}
},
{
path: '/blogs',
name: 'Blogs',
component: Blogs
},{
path: '/Login',
name: 'Login',
component: Login
},{
path: '/blog/add',
name: 'BlogEdit',
component: BlogEdit,
meta: {
requireAuth: true
}
}, {
path: '/Demo',
name: 'Demo',
component: Demo
},{
path: '/blog/:blogid',
name: 'BlogDetail',
component: BlogDetail
} ,{
path: '/blog/:blogid/edit',
name: 'BlogEdit',
component: BlogEdit,
meta: {
requireAuth: true
}
}
]})
然后我们再main.js中import我们的permission.js
src/main.js添加: import ‘./permission.js’ // 路由拦截
// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
