篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了SSM框架整合相关的知识，希望对你有一定的参考价值。

烦了我几天，年都没心情过，今晚终于搞定了。做了一个简单的ssm整合demo。用到了逆向工程，注解配置。

工程结构

util包里面放的是逆向工程java类的代码，也可以用eclipse插件自动生成，因为之前下载有点问题就索性找了段代码来实现逆向工程。具体操作网搜这里不多说了。
mybytis配置文件(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>

<typeAliases>
<package name="com.eangaie.model" />
</typeAliases>

</configuration>
数据库配置（jdbc.properties）
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/yanjie?characterEncoding=utf-8
jdbc.username=root
jdbc.password=123456
Spring配置文件

约束这里就不加进去了太占空间
4.1 applicationContext-dao.xml



<context:property-placeholder location="classpath:properties/*.properties" />

<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
destroy-method="close">
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="driverClassName" value="${jdbc.driver}" />
<property name="maxActive" value="10" />
<property name="minIdle" value="5" />
</bean>


<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

<property name="dataSource" ref="dataSource" />

<property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml" />
</bean>

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.eangaie.mapper" />
</bean>

注意这里要把mapper文件和对应的java文件都放在mapper包下面！
4.2.applicationContext-service.xml

<context:component-scan base-package="com.eangaie.service"/>

4.3 事务管理applicationContext-trans.xml

<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

<property name="dataSource" ref="dataSource" />
</bean>

<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>

<tx:method name="save*" propagation="REQUIRED" />
<tx:method name="insert*" propagation="REQUIRED" />
<tx:method name="add*" propagation="REQUIRED" />

</tx:attributes>
</tx:advice>

<aop:advisor advice-ref="txAdvice"

</aop:config>

4.4 springmvc配置文件

    <mvc:annotation-driven />
    
    <mvc:resources location="/js/" mapping="/js/**" />
    <mvc:resources location="/css/" mapping="/css/**" />
    <bean

        <property name="prefix" value="/view/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>

mapper文件
mapper文件和对应的java文件，这里就没有手写了，通过mybatis逆向工程生成的。同样的模型层也如此
service层
10.1 接口
package com.eangaie.service;

import com.eangaie.model.User;

public interface userService {

    void insertUser(User user) throws Exception;

    void deleteUser(int id) throws Exception;

    void updateUser(int id,User user) throws Exception;

    User selectUser(int id) throws Exception;
}
10.2 实现类
记得加上@Service注解哦！！
package com.eangaie.service.impl;

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

import com.eangaie.mapper.UserMapper;
import com.eangaie.model.User;
import com.eangaie.service.userService;
@Service
public class userServiceImpl implements userService {

    @Autowired//自动填充usermapper
    UserMapper usermapper;
    @Override
    public void insertUser(User user) throws Exception {
        // TODO Auto-generated method stub
        usermapper.insert(user);
    }

    @Override
    public void deleteUser(int id) throws Exception {
        // TODO Auto-generated method stub
        usermapper.deleteByPrimaryKey(id);
    }

    @Override
    public void updateUser(int id,User user) throws Exception {
        // TODO Auto-generated method stub
        usermapper.updateByPrimaryKey(user);
    }

    @Override
    public User selectUser(int id) throws Exception {
        // TODO Auto-generated method stub
        User user = new User();
        user=usermapper.selectByPrimaryKey(id);
        return user;
    }

}
控制层
package com.eangaie.controller;

import javax.servlet.http.HttpServletRequest;

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

import com.eangaie.model.User;
import com.eangaie.service.userService;

@Controller// 不能漏
public class userController {
    @Autowired
    userService userservice;
    @RequestMapping("/getUser")
    public String getUser(HttpServletRequest request) throws Exception {
        User user=new User();
        user=userservice.selectUser(1);
        request.setAttribute("user", user);
        return "success";
    }
}

最后部署Tomcat运行访问
http://localhost:8080/ssm/getUser

大功告成!
