ssm整合案例 一、新建maven工程

如果有如下报错

处理方式

右键项目名，如图

报错消失，新建完成

插入一个其他可能会遇到的问题，web.xml文件的web-app那里报错

如图：(没报错的话可以直接跳到下一步添加依赖)

解决方法

二、添加依赖

再pom.xml文件中添加要用到的依赖

下面是我用的，也可以自行选择其他版本

 <!-- 统一管理spring jar包的版本 -->
	<properties>

添加好后ctrl+s保存，就会自动下载了，如图

如果没有添加成功，按下面的步骤 *** 作

添加完成

三、配置文件

在src/main/resources右键，新建配置文件

配置文件内容如下：

db.properties

（我这里是mysql8，mysql5需要另行配置）

（数据库名，账号，密码改成自己电脑上的）

driver=com.mysql.cj.jdbc.Driver
url=jdbc:mysql://localhost:3306/iflytek02?characterEncoding=utf-8&serverTimezone=UTC&useSSL=false
username=root
password=111
SqlMapConfig.xml 
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
  PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!-- 别名配置 -->
  <typeAliases>
  <!-- mapper的xml文件中用到com.iflytek.pojo包下的所有的类，直接用类名作为别名 -->
  <!-- 可以根据自己想要的包名配置、修改 -->
  	<package name="com.iflytek.pojo"/>
  </typeAliases>
</configuration>
applicationContext-dao.xml

(实际上配的就是spring的IOC的这部分功能)

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:p="http://www.springframework.org/schema/p"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd

        http://www.springframework.org/schema/aop
        https://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/tx
        https://www.springframework.org/schema/tx/spring-tx.xsd">

	<!-- 加载数据库连接的属性文件 -->
	<context:property-placeholder  location="classpath:db.properties"/>


    <!-- 配置dbcp2的数据源 -->
	 <bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource"
        destroy-method="close"
        p:driverClassName="${driver}"
        p:url="${url}"
        p:username="${username}"
        p:password="${password}"/>
        
        
    <!--SqlSessionFactory的配置 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
     	<property name="dataSource" ref="dataSource"/>
     	<!-- 配置mybatis的配置文件 -->
     	<property name="configLocation" value="classpath:SqlMapConfig.xml"/>
    </bean>
    
    <!--mapper的扫描器-->
    <bean  class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    	<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
    	<!-- 自动生成com.iflytek.mapper下所有接口实现类的对象 -->
    	<property name="basePackage" value="com.iflytek.mapper"/>
    </bean>
    
    
</beans>
log4j

(没啥说的，直接复制贴上去完事)

# Global logging configuration
#\u5728\u5f00\u53d1\u73af\u5883\u4e0b\u65e5\u5fd7\u7ea7\u522b\u8981\u8bbe\u7f6e\u6210DEBUG\uff0c\u751f\u4ea7\u73af\u5883\u8bbe\u7f6e\u6210info\u6216error
log4j.rootLogger=DEBUG, stdout
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

applicationContext-tx.xml配置文件在【五、spring业务层整合】里

springmvc.xml配置文件在【六、整合springmvc】里

四、工程结构

根据自己需要用到的表，编写dao层代码

我用到的表：

编写dao层代码：

package com.iflytek.pojo;

public class Dept {
	
	private Integer deptno;
	
	private String dname;
	
	private String loc;
	
	public Integer getDeptno() {
		return deptno;
	}

	public void setDeptno(Integer deptno) {
		this.deptno = deptno;
	}

	public String getDname() {
		return dname;
	}

	public void setDname(String dname) {
		this.dname = dname;
	}

	public String getLoc() {
		return loc;
	}

	public void setLoc(String loc) {
		this.loc = loc;
	}


}

新建接口，写增删改查方法：

(这里就用增来举例了)

package com.iflytek.mapper;

import com.iflytek.pojo.Dept;

public interface DeptMapper {
	
	int addDept(Dept dept);
	
//	int updateDept(Dept dept);
//	
//	int deleteDept(Dept dept);
//	
//	int findDept(Dept dept);

}

DeptMapper.xml映射文件：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
  PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.iflytek.mapper.DeptMapper">
	
	<insert id="addDept" parameterType="Dept">
		insert into dept(deptno,dname,loc) values(#{deptno},#{dname},#{loc})
	</insert>

</mapper>
五、spring业务层整合

DeptService接口

package com.iflytek.service;

import com.iflytek.pojo.Dept;

public interface DeptService {

	/* 添加部门 */
	int add(Dept dept) throws Exception;

}

DeptServiceImpl实现类

package com.iflytek.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.iflytek.mapper.DeptMapper;
import com.iflytek.pojo.Dept;
import com.iflytek.service.DeptService;

@Service("deptService")
public class DeptServiceImpl implements DeptService {
	
	@Autowired
	private DeptMapper deptMapper;

	@Override
	public int add(Dept dept) throws Exception {
			
		return deptMapper.addDept(dept);
	}

}
applicationContext-tx.xml

声明式事务的配置applicationContext-tx.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:p="http://www.springframework.org/schema/p"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        https://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/aop
        https://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/tx
        https://www.springframework.org/schema/tx/spring-tx.xsd">

	<!-- 配置事务管理器 -->
	<bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"
	 p:dataSource-ref="dataSource" /> 
	
	<!--  配置事务的通知器 -->
	 <tx:advice id="txAdvice" transaction-manager="txManager" >
		<tx:attributes>
			<tx:method name="add*"    propagation="REQUIRED" rollback-for="Exception" />
			<tx:method name="save*"   propagation="REQUIRED" rollback-for="Exception"/>
			<tx:method name="update*" propagation="REQUIRED" rollback-for="Exception"/>
			<tx:method name="modify*" propagation="REQUIRED" rollback-for="Exception"/>
			<tx:method name="delete*" propagation="REQUIRED" rollback-for="Exception"/>
			<tx:method name="find*"   propagation="SUPPORTS"/>
			<tx:method name="select*" propagation="SUPPORTS"/>
		</tx:attributes>
	</tx:advice> 
	 
	 <!--  切点表达式 -->
	  <aop:config>
	   <aop:pointcut expression="execution(* com.iflytek.service.*.*(..))" id="serviceMethod"/>
	   <aop:advisor advice-ref="txAdvice" pointcut-ref="serviceMethod"/>
	 </aop:config> 
	  
    
</beans>
六、整合SpringMVC springmvc.xml 
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc
        https://www.springframework.org/schema/mvc/spring-mvc.xsd
         http://www.springframework.org/schema/context
        https://www.springframework.org/schema/context/spring-context.xsd">

	<!-- 开启springmvc的注解驱动 -->
	<mvc:annotation-driven />
	
	<!-- 开启组件扫描 -->
	<context:component-scan base-package="com.iflytek "/>

</beans>

配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
  <display-name>dept</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
    <!--   配置springmvc的前端控制器DispatcherServlet -->
  <servlet>
  	<servlet-name>springmvc01</servlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  	<init-param>
  		<param-name>contextConfigLocation</param-name>
  		<param-value>classpath:springmvc.xml</param-value>
  	</init-param>
  </servlet>
  
  <servlet-mapping>
  	<servlet-name>springmvc01</servlet-name>
  	<url-pattern>*.do</url-pattern>
  </servlet-mapping>
  
<!--   将spring的dao层和事务transection的配置加入容器管理中 -->
  <context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:applicationContext-*.xml</param-value>
 </context-param>
	
  <!--  配置监听器，监听容器范围内各个bean的变化 -->
 <listener>
 	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 </listener> 
  
</web-app>

Controller代码

package com.iflytek.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import com.iflytek.pojo.Dept;
import com.iflytek.service.DeptService;

@Controller
public class DeptController {

	@Autowired
	private DeptService deptService;
	
	@RequestMapping("add.do")
	public ModelAndView add(Dept dept) throws Exception {
		ModelAndView mv = new ModelAndView();
		int i = deptService.add(dept);
		if(i==1) {
			mv.setViewName("index.jsp");
		} else {
			mv.setViewName("add.jsp");
			
		}
		return mv;
	}
}
七、写界面测试

写界面

新建jsp文件，如果出现如下错误，如图

处理方法：

右键项目，build path

报错消失

add.jsp 
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>添加部门</title>
</head>
<body>
	<form action="add.do" method="post">
		部门编号 <input type="text" name="deptno"><br>
		部门名称 <input type="text" name="dname"><br>
		所在城市 <input type="text" name="loc"><br>
		<input type="submit" value="添加部门">
	</form>
</body>
</html>
index.jsp 
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
success!
</body>
</html>

启动服务器

添加部门

刷新数据库

添加成功！！！
