基于SpringBoot+Vue的前后端分离练习项目

基于SpringBoot+Vue的前后端分离练习项目,第1张

1、项目介绍

这是一款基于SpringBoot+Vue的前后端分离的项目,麻雀虽小,五脏俱全,值得拥有!

全部源码放到文章最后

页面展示:

  • 用户主页
  • 管理员后台界面
2、技术选型
  • 后端
    SpringBoot
    Hutool工具类库(*超好用)
    Redis缓存 (缓解多次刷新数据库压力)
    Lombok(减少写get、set等方法)
    Mysql5.7+
    Mybatis
    ​ Mybatis-Plus

  • 前端
    ​ Vue2
    ​ Vue-Router
    ​ VueX
    ​ ElementUI
    ​ Apache ECharts (可视化图标插件)
    ​ Axios
    ​ 高德地图Api

3、数据库设计

Mysql5.7+ 、Nvaicat(MySQL可视化工具)

字符集
utf8mb4
排序规则
utf8mb4_unicode_ci

4、SpringBoot

开发模式

以User为例

Entity

Entity实体层与数据库属性一一对应,lombok注解简化封装方法

package sqgxy.xmp.springboot.entity;

import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;

import java.io.Serializable;
import java.util.Date;
import java.util.List;

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Getter;
import lombok.Setter;
import lombok.ToString;

@Getter
@Setter
@TableName("sys_user")
@ApiModel(value = "User对象", description = "")
@ToString
public class User implements Serializable {

    private static final long serialVersionUID = 1L;

    @ApiModelProperty("id")
    @TableId(value = "id", type = IdType.AUTO)
    private Integer id;

    @ApiModelProperty("用户名")
    private String username;

    @ApiModelProperty("密码")
    private String password;

    @ApiModelProperty("昵称")
    private String nickname;

    @ApiModelProperty("邮箱")
    private String email;

    @ApiModelProperty("电话")
    private String phone;

    @ApiModelProperty("地址")
    private String address;

    @ApiModelProperty("创建时间")
    private Date createTime;

    @ApiModelProperty("头像")
    private String avatarUrl;

    @ApiModelProperty("角色")
    private String role;

    @TableField(exist = false)
    private List courses;

    @TableField(exist = false)
    private List stuCourses;

}
mapper

mapper层对数据库进行数据持久化 *** 作

package sqgxy.xmp.springboot.mapper;

import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import sqgxy.xmp.springboot.controller.dto.UserPasswordDTO;
import sqgxy.xmp.springboot.entity.User;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Update;

/**
 * @author xmp
 * @date 2022/5/12
 */
public interface UserMapper extends BaseMapper {

    @Update("update sys_user set password = #{newPassword} where username = #{username} and password = #{password}")
    int updatePassword(UserPasswordDTO userPasswordDTO);

    Page findPage(Page page, @Param("username") String username, @Param("email") String email, @Param("address") String address);
}

UserMapper.xml





    
        
        
        
        
        
        
        
        
        
        
            
            
        
        
            
            
        
    

    


service层

即为业务逻辑层,可以理解为对一个或者多个dao进行得再次封装,主要是针对具体的问题的 *** 作,把一些数据层的 *** 作进行组合,间接与数据库打交道(提供 *** 作数据库的方法)。要做这一层的话,要先设计接口,再实现类

5、Vue 

目录结构

跨域问题

安装axios: npm i axios -S

解决跨域问题,前端8080端口,请求数据后端9090端口

import axios from 'axios'
import router from "@/router";
import {serverIp} from "../../public/config";

const request = axios.create({
    baseURL: `http://${serverIp}:9090`,
    timeout: 30000
})

// request 拦截器
// 可以自请求发送前对请求做一些处理
// 比如统一加token,对请求参数统一加密
request.interceptors.request.use(config => {
    config.headers['Content-Type'] = 'application/json;charset=utf-8';
    let user = localStorage.getItem("user") ? JSON.parse(localStorage.getItem("user")) : null
    if (user) {
        config.headers['token'] = user.token;  // 设置请求头
    }

    return config
}, error => {
    return Promise.reject(error)
});

// response 拦截器
// 可以在接口响应后统一处理结果
request.interceptors.response.use(
    response => {
        let res = response.data;
        // 如果是返回的文件
        if (response.config.responseType === 'blob') {
            return res
        }
        // 兼容服务端返回的字符串数据
        if (typeof res === 'string') {
            res = res ? JSON.parse(res) : res
        }
        // 当权限验证不通过的时候给出提示
        if (res.code === '401') {
            // ElementUI.Message({
            //     message: res.msg,
            //     type: 'error'
            // });
            router.push("/login")
        }
        return res;
    },
    error => {
        console.log('err' + error) // for debug
        return Promise.reject(error)
    }
)


export default request


页面开发

看文档、B站讲解

Element-Ui

官网地址:https://element.eleme.io/#/zh-CN/component/installation

Apache ECharts

官网地址:https://echarts.apache.org/handbook/zh/get-started/

6、项目部署 环境:

centos7、jdk8、mysql、Redis、nginx

远程连接工具Xshell、Xftp

Vue打包

dist文件夹:

​ npm run build

SpringBoot打包

按步骤

​ 先清除,在编译,最后打包

上传之后

nginx

配置一下前端页面

location / {
      root  /public/app/dist;      ===>自己的路径
      index index.html index.html index.htm;
  }
Boot

后台启动命令

nohup java -jar xxx &

7、效果外链

http://180.76.56.118:80/login

为了展示全部效果,注册账号时默认为管理员,登入直接到后台。

管理员访问前端页面地址:http://180.76.56.118/front/home

普通用户,账号:222,密码:222,登入可直接到前端页面。

浏览器会缓存用户信息,所以管理员和用户切换时,可以F12清理缓存,目前这个算是个小bug。
