2、整合思路

1、先搭建整合的环境
2、先把Spring的配置搭建完成
3、再使用Spring整合SpringMVC框架
4、之后使用Spring整合MyBatis框架
5、最后spring整合mybatis框架配置事务（Spring的声明式事务管理）

3、创建数据库和表格结构

create database ssm整合;
use ssm整合;
create table amount(
id int primary key auto_increment,
name varchar(50),
money double
);

4、创建maven工程

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.7</maven.compiler.source>
    <maven.compiler.target>1.7</maven.compiler.target>

      <version>4.12</version>
      <scope>test</scope>
    </dependency>
  </dependencies>

5、编写实体类

package com.lc.entity;

import java.io.Serializable;


public class Amount implements Serializable {
    private Integer id;
    private String name;
    private Double money;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Double getMoney() {
        return money;
    }

    public void setMoney(Double money) {
        this.money = money;
    }

    @Override
    public String toString() {
        return "Account{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", money=" + money +
                '}';
    }
}

六、编写dao层接口

package com.lc.dao;

import com.lc.entity.Amount;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;

import java.util.List;


public interface AmountDao {
     
     List<Amount> findAll();
     
     void saveAccount(Amount account);
}

7、编写service层接口以及实现类

service接口

package com.lc.service;

import com.lc.entity.Amount;

import java.util.List;

public interface AmountService {
    // 查询所有账户
    public List<Amount> findAll();

    // 保存帐户信息
    public void saveAccount(Amount amount);
}

实现类

package com.lc.service.Impl;

import com.lc.dao.AmountDao;
import com.lc.entity.Amount;
import com.lc.service.AmountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service("amountService")
public class AmountServiceImpl implements AmountService {

    @Override
    public List<Amount> findAll() {
        System.out.println("Service业务层：查询所有账户...");
        return null;
    }

    @Override
    public void saveAccount(Amount amount) {
        System.out.println("Service业务层：保存帐户...");
    }
}

二、Spring框架代码编写

1、创建resources目录管理XML配置文件

2、编写applicationContext.xml文件

编写具体的配置信息

<?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:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
	http://www.springframework.org/schema/beans/spring-beans.xsd
	http://www.springframework.org/schema/context
	http://www.springframework.org/schema/context/spring-context.xsd
	http://www.springframework.org/schema/aop
	http://www.springframework.org/schema/aop/spring-aop.xsd
	http://www.springframework.org/schema/tx
	http://www.springframework.org/schema/tx/spring-tx.xsd">

    <!--开启注解的扫描，希望处理service和dao，controller不需要Spring框架去处理-->
    <context:component-scan base-package="com.lc" >
        <!--配置哪些注解不扫描-->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" />
    </context:component-scan>
</beans>

3、测试

测试代码

package com.lc.test;

import com.lc.entity.Amount;
import com.lc.service.AmountService;
import org.springframework.context.support.ClassPathXmlApplicationContext;


public class TestSpring {
    public static void main(String[] args) {
        ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
        AmountService amountService = (AmountService)applicationContext.getBean("amountService");
        amountService.saveAccount(new Amount());
    }
}

在这里插入图片描述

如上图结果，表示Spring环境搭建成功

三、SpringMVC框架代码编写

1、在web.xml中配置dispatcherServlet前端控制器

 <!--配置前端控制器-->
    <servlet>
        <servlet-name>dispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!--加载springmvc.xml配置文件-->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springmvc.xml</param-value>
        </init-param>
        <!--启动服务器，创建该servlet-->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
<!--解决中文乱码的过滤器-->
    <filter>
        <filter-name>characterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

2、配置SpringMVC.xml文件

<?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
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">
    <!--开启注解扫描，只扫描Controller注解-->
    <context:component-scan base-package="com.lc">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!--配置的视图解析器对象-->
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/pages/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
    <!--过滤静态资源-->
    <mvc:resources location="/css" mapping="/css/**"/>
    <mvc:resources location="/images/" mapping="/images/**"/>
    <mvc:resources location="/js/" mapping="/js/**"/>
    <!--开启SpringMVC注解的支持-->
    <mvc:annotation-driven/>
</beans>

3、创建JSP页面，编写controller代码

jsp页面

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<body>
<a href="account/findAll">测试SpringMVC查询</a>
</body>
</html>

controller层代码

package com.lc.controller;

import com.lc.entity.Amount;
import com.lc.service.AmountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.List;

@Controller
public class AmountController {
    @RequestMapping(value = "/amount/findAll", method = RequestMethod.GET)
    public String findAll(Model model){
        System.out.println("Controller表现层：查询所有账户...");
        //在视图解析器中配置了前缀后缀
        return "list";
    }

在WEB-INF的pages目录下创建controller跳转的list.jsp页面

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<%@ page contentType="text/html;charset=UTF-8" language="java" %>

<html>
<head>
    <title>Title</title>
</head>
<body>
<h2>查询所有的账户成功</h2>
</body>
</html>

4、部署Tomcat进行测试

在这里插入图片描述

如上图所试，SpringMVC环境搭建成功。

四、Spring整合SpringMVC框架

1、整合原理分析

整合成功的表现：在controller（SpringMVC）中能成功的调用service（Spring）对象中的方法。
要想在controller中调用service方法，就要注入service到controller中来，有service对象才可以调用service方法，方法是这样没有错，但是有一个问题，就是启动Tomcat之后，在web.xml中配置有前端控制器，web容器会帮我们加载springmvc.xml配置文件，在springmvc.xml配置文件中我们配置情况是只扫描controller层，没有扫描service和dao层，导致spring.xml文件就从头到尾没有执行过，spring中的配置扫描自然也没有被扫描到，就相当于没有将spring配置到IOC容器当中去，所以，现在的解决方案就是，在启动服务器时就加载spring配置文件,这时候监听器listener就派上用场了。

2、在web.xml中配置ContextLoaderListener监听器

方法一：把applicationContext.xml配置文件配置到WEB-INF目录下，因为监听器只能加载WEB-INF目录下的applicationContext.xml的配置文件。
方法二：在web.xml配置监听器加载路径
推荐使用第二种方法：因为我们在整合过程中会有许多配置文件，我们自定义一个类似pages资源文件夹专门管理这些配置文件，方便管理、维护

3、controller中注入service对象，调用方法并且测试

controller层代码

package com.lc.controller;

import com.lc.entity.Amount;
import com.lc.service.AmountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.List;

@Controller
public class AmountController {

    @Autowired
    private AmountService amountService;

    @RequestMapping(value = "/amount/findAll", method = RequestMethod.GET)
    public String findAll(Model model){
        System.out.println("Controller表现层：查询所有账户...");
        List<Amount> list = amountService.findAll();
        //在视图解析器中配置了前缀后缀
        return "list";
    }

测试
如上如所试，说明Spring整合SpringMVC成功

五、MyBatis框架代码的编写

1、使用注解的方式，在接口上面编写sql语句

package com.lc.dao;

import com.lc.entity.Amount;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface AmountDao {
     @Select("select * from account")
     List<Amount> findAll();
     @Insert("insert into account (name,money) values(#{name},#{money})")
     void saveAccount(Amount account);
}

2、创建SqlMapConfig.xml文件

<?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>
    <environments default="mysql">
        <environment id="mysql">
            <transactionManager type="JDBC"/>
            <dataSource type="POOLED">
                <property name="driver" value="com.mysql.jdbc.Driver"/>
                <property name="url" value="jdbc:mysql:///ssm整合"/>
                <property name="username" value="root"/>
                <property name="password" value="admin123"/>
            </dataSource>
        </environment>
    </environments>
    <!-- 使用的是注解 -->
    <mappers>
        <package name="com.lc.dao"/>
    </mappers>
</configuration>

3、测试

测试代码

package com.lc.test;

import com.lc.dao.AmountDao;
import com.lc.entity.Amount;
import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;

import java.io.IOException;
import java.io.InputStream;
import java.util.List;


public class TestMybatis {
    public static void main(String[] args) throws IOException {
        Amount amount = new Amount();
        amount.setName("詹姆斯");
        amount.setMoney(2000d);
        /*//加载配置文件
        InputStream inputStream = Resources.getResourceAsStream("sqlMapConfig.xml");
        //参加SqlSessionFactory对象
        SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
        //创建sqlSession对象
        SqlSession sqlSession = sqlSessionFactory.openSession();
        //获取代理对象
        AmountDao mapper = sqlSession.getMapper(AmountDao.class);
        //保存
        mapper.saveAccount(amount);
        //提交事物
        sqlSession.commit();
        //关闭资源
        sqlSession.close();
        inputStream.close();*/

        //加载配置文件
        InputStream inputStream = Resources.getResourceAsStream("sqlMapConfig.xml");
        //创建SqlSessionFactory对象
        SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
        //创建sqlSession对象
        SqlSession sqlSession = sqlSessionFactory.openSession();
        //获取代理对象
        AmountDao mapper = sqlSession.getMapper(AmountDao.class);
        //查询所有
        List<Amount> amountList = mapper.findAll();
        for (Amount list : amountList) {
            System.out.println(list);
        }
    }
}

如上图所示，mybatis环境搭建成功

六、Spring整合Mybatis框架

1、整合原理分析

整合成功的表现：Service层能成功调用dao对象，能够做查询操作或者新增数据能存进数据库。
现在spring已经是在IOC容器中了，dao是一个接口，可以通过程序帮这个接口生成代理对象，我们要是可以把这个代理对象也放进IOC容器，那么service就可以拿到这个对象，之后在service中做一个注入，service从而调用dao代理对象的方法。
整合过程：把SqlMapConfig.xml配置文件中的内容配置到applicationContext.xml配置文件中。

2、在applicationContext.xml中配置数据库连接池

<!--配置连接池-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="com.mysql.jdbc.Driver"/>
        <property name="jdbcUrl" value="jdbc:mysql:///ssm整合"/>
        <property name="user" value="root"/>
        <property name="password" value="admin123"/>
    </bean>

3、在applicationContext.xml中配置SqlSessionFactory工厂

没配置工厂之前，测试的时候，每次都要先创建工厂，因为工厂能够给我们创建SqlSession,有了SqlSession就可以通过SqlSession拿到代理对象。现在我们直接在applicationContext.xml中配置SqlSessionFactory工厂，这就相当于IOC容器中有了工厂，就可以去创建SqlSession，进而通过SqlSession拿到代理对象，没必要每次测试都去创建工厂。

 <!--配置SqlSessionFactory工厂-->
<bean id="sqlSessonFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
 </bean>

4、在applicationContext.xml中配置Acount接口所在包

<!--配置AcountDao接口所在包-->
    <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.lc.dao"/>
    </bean>

上面的操作其实就是把mybatis中的配置（SqlMapConfig.xml）转移到spring中去，让它产生代理并存到IOC容器中！

5、编写service和controller层代码

service层

package com.lc.service.Impl;

import com.lc.dao.AmountDao;
import com.lc.entity.Amount;
import com.lc.service.AmountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service("amountService")
public class AmountServiceImpl implements AmountService {

    @Autowired
    private AmountDao amountDao;

    @Override
    public List<Amount> findAll() {
        System.out.println("Service业务层：查询所有账户...");
        return amountDao.findAll();
    }

    @Override
    public void saveAccount(Amount amount) {
        System.out.println("Service业务层：保存帐户...");
        amountDao.saveAccount(amount);
    }
}

controller层

package com.lc.controller;

import com.lc.entity.Amount;
import com.lc.service.AmountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.List;

@Controller
public class AmountController {

    @Autowired
    private AmountService amountService;

    @RequestMapping(value = "/amount/findAll", method = RequestMethod.GET)
    public String findAll(Model model){
        System.out.println("Controller表现层：查询所有账户...");
        List<Amount> list = amountService.findAll();
        model.addAttribute("list",list);
        //在视图解析器中配置了前缀后缀
        return "list";
    }

6、编写list.jsp页面

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<%@ page contentType="text/html;charset=UTF-8" language="java" %>

<html>
<head>
    <title>Title</title>
</head>
<body>
<h2>查询所有的账户成功</h2>
<c:forEach items="${list}" var="amount">
    ${amount.name}
    ${amount.money}<br/>
</c:forEach>

</body>
</html>

7、测试

如上图所示，表示Spring整合Mybatis成功

7、Spring整合Mybatis框架的事务配置（Spring的声明式事务管理）

在整合spring、mybatis测试的时候，新增数据保存的时手动的提交过事务 session.commit()，如果不写这一句，就会出现数据没提交的情况，因此为了完美的整合ssm，我们必须配置Spring的声明式事务管理.

1、在applicationContext.xml中配置Spring框架声明式事务管理

<!--配置Spring框架声明式事务管理-->
    <!--配置事务管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!--配置事务通知-->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="find*" read-only="true"/>
            <tx:method name="*" isolation="DEFAULT"/>
        </tx:attributes>
    </tx:advice>

    <!--配置AOP增强-->
    <aop:config>
        <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.lc.service.Impl.*ServiceImpl.*(..))"/>
    </aop:config>

2、编写index.jsp代码

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<body>

<a href="amount/findAll">测试SpringMVC查询</a>

<h3>测试</h3>

<form action="amount/save" method="post">
    姓名:<input type="text" name="name"/><br/>
    金额:<input type="text" name="money"/><br/>
    <input type="submit" value="保存"/>
</form>

</body>
</html>

3、编写service、controller层代码

service

package com.lc.service.Impl;

import com.lc.dao.AmountDao;
import com.lc.entity.Amount;
import com.lc.service.AmountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service("amountService")
public class AmountServiceImpl implements AmountService {

    @Autowired
    private AmountDao amountDao;

    @Override
    public List<Amount> findAll() {
        System.out.println("Service业务层：查询所有账户...");
        return amountDao.findAll();
    }

    @Override
    public void saveAccount(Amount amount) {
        System.out.println("Service业务层：保存帐户...");
        amountDao.saveAccount(amount);
    }
}

controller层

package com.lc.controller;

import com.lc.entity.Amount;
import com.lc.service.AmountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.List;

@Controller
public class AmountController {

    @Autowired
    private AmountService amountService;

    @RequestMapping(value = "/amount/findAll", method = RequestMethod.GET)
    public String findAll(Model model){
        System.out.println("Controller表现层：查询所有账户...");
        List<Amount> list = amountService.findAll();
        model.addAttribute("list",list);
        //在视图解析器中配置了前缀后缀
        return "list";
    }

    @RequestMapping(value = "/amount/save",method = RequestMethod.POST)
    public void save(Amount amount, HttpServletRequest httpServletRequest,HttpServletResponse httpServletResponse) throws IOException {
        amountService.saveAccount(amount);
        httpServletResponse.sendRedirect(httpServletRequest.getContextPath()+"/amount/findAll");
        return;
    }
}

4、测试
