pom.xml

1.1.3、导入坐标建立依赖
注意 MyBatis和 Spring的版本对应关系：

1.1.4、编写实体类
1.1.5、编写业务层接口
1.1.6、编写持久层接口

1.2、整合步骤
1.2.1、保证Spring框架在web工程中独立运行
1.2.1.1、第一步：编写spring配置文件并导入约束

</beans>

applicationContext.xml

1.2.1.2、第二步：使用注解配置业务层和持久层

1.2.1.3、第三步：测试spring能否独立运行

public class TestSpring {
    
    @Test
    public void run1(){
        //加载配置文件
        ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
        //获取对象
        AccountService accountService = (AccountService) ac.getBean("accountService");
        //调用方法
        accountService.findAll();
    }
    
}

TestSpring.jacva

1.2.2、保证SpringMVC在web工程中独立运行
1.2.2.1、第一步：在web.xml中配置核心控制器（DispatcherServlet）

<!DOCTYPE web-app PUBLIC
        "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
        "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Archetype Created Web Application</display-name>

  <!--配置Spring的监听器，默认只加载WEB-INF目录下的applicationContext.xml配置文件-->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <!--设置配置文件的路径-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  <context-param>
    <param-name/>
    <param-value/>
  </context-param>

  <!--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>

</web-app>

web.xml

1.2.2.2:、第二步：编写SppringMVC的配置文件

<?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="cn.itcast">
    <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>

pringmvc.xml

1.2.2.3、第三步：编写Controller和jsp页面

@Controller
@RequestMapping("/account")
public class AccountController {
    
    @Autowired
    private AccountService accountService;
    
    @RequestMapping("/findAll")
    public String findAll(Model model){
        System.out.println("表现层：查询所有账户");
        //调用service方法
        List<Account> accounts = accountService.findAll();
        model.addAttribute("list", accounts);
        return "list";
    }

    @RequestMapping("/save")
    public void save(Account account, HttpServletRequest request, HttpServletResponse response) throws IOException {
        System.out.println("表现层：保存账户");
        accountService.saveAccount(account);
        response.sendRedirect(request.getContextPath()+"/account/findAll");
        return;
//        return "list";
    }
    
}

AccountController

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

    <a href="account/findAll">测试查询</a>

    <h3>测试保存</h3>
    
    <form action="account/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"/><br/>
    </form>

</body>
</html>

index.jsp

1.2.3、整合Spring和SpringMVC
存在的问题：
　　启动toomcat。web中的前端控制器会去加载springmvc.xml配置文件。
　　但是在springmvc中只配置了扫描了@Controller的注解。-->expression="org.springframework.stereotype.Controller"
　　applicationContext.xml 这个配置文件从头至尾没有被加载过。
　　因此里面配置的扫描没有生效，xxxServiceImpl类的实例没有被加载到IOC容器中。因此无法注入。
解决：
　　在启动服务器的时候将spring的配置文件applicationContenxt.xml也加载进来。
　　因为只有放到容器后，才能去完成依赖注入。
原理：

1.2.3.1、第一步：配置监听器实现启动服务创建容器。web.xml中
　　Spring监听器，类ContextLoaderListener默认只加载WEB-INF目录下的applicationContext.xml配置文件。
　　需要重新设置到类路径下，方便统一管理。
　　那么，此时服务器启动就会加载applicationContext.xml配置文件。

  <!--配置Spring的监听器，默认只加载WEB-INF目录下的applicationContext.xml配置文件-->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <!--设置配置文件的路径-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  <context-param>
    <param-name/>
    <param-value/>
  </context-param>

1.2.4、保证MyBatis框架在web工程中独立运行
1.2.4.1、第一步：编写AccountDao映射配置文件--->也可以直接使用注解
1.2.4.2、编写SqlMapConfig配置文件

<?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"/>                
        <property name="username" value="root"/>                
        <property name="password" value="root"/>            
      </dataSource>        
    </environment>    
  </environments>        
  <!-- 使用的是注解 -->    
  <mappers>        
    <!-- <mapper class="cn.itcast.dao.AccountDao"/> -->        
    <!-- 该包下所有的dao接口都可以使用 -->        
    <package name="cn.itcast.dao"/>    
  </mappers> 
</configuration>

SqlMapConfig.xml

public class TestMybatis {

    /**测试查询
     * @throws Exception
     */
    @Test
    public void run1() throws Exception {
        //加载配置文件
        InputStream in = Resources.getResourceAsStream("SqlMapConfig.xml");
        //创建SqlSessionFactory
        SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(in);
        //创建sqlSession对象
        SqlSession session = factory.openSession();
        //获取到代理对象
        AccountDao accountDao = session.getMapper(AccountDao.class);
        //查询所有的数据
        List<Account> accounts = accountDao.findAll();
        for (Account account:accounts){
            System.out.println(account);
        }
        //关闭资源
        session.close();
        in.close();
    }

    /**测试保存
     * @throws Exception
     */
    @Test
    public void run2() throws Exception {
        Account account = new Account();
        account.setName("payn");
        account.setMoney(500d);
        
        //加载配置文件
        InputStream in = Resources.getResourceAsStream("SqlMapConfig.xml");
        //创建SqlSessionFactory
        SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(in);
        //创建sqlSession对象
        SqlSession session = factory.openSession();
        //获取到代理对象
        AccountDao accountDao = session.getMapper(AccountDao.class);
        
        accountDao.saveAccount(account);
        
        //提交事务
        session.commit();
        
        //关闭资源
        session.close();
        in.close();
    }
}

TestMyBatis.java

1.2.4.3、测试运行结果

1.2.5、整合Spring和MyBatis
整合思路：
　　把 mybatis 配置文件（SqlMapConfig.xml）中内容配置到 spring 配置文件中。
　　同时，把 mybatis 配置文件的内容清掉。

<?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"/>                
        <property name="username" value="root"/>                
        <property name="password" value="root"/>            
      </dataSource>        
    </environment>    
  </environments>        
  <!-- 使用的是注解 -->    
  <mappers>        
    <!-- <mapper class="cn.itcast.dao.AccountDao"/> -->        
    <!-- 该包下所有的dao接口都可以使用 -->        
    <package name="cn.itcast.dao"/>    
  </mappers> 
</configuration>

SqlMapConfig.xml

注意：
　　由于如果我们使用的是代理 Dao的模式，Dao具体实现类由 MyBatis 使用代理方式创建，所以此时 mybatis 配置文件不能删。
　　整合 spring 和 mybatis 时，mybatis 创建的 Mapper.xml 文件名必须和 Dao接口文件名一致。

1.2.5.1、第一步：Spring接管MyBatis的Session工厂

jdbcConfig.properties：
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql:///ssm
jdbc.username=root
jdbc.password=root

原理：
　　service的对象已经放到 IOC 容器中了。
　　dao是一个接口，但是MyBatis框架会生成一个代理对象。
　　将Mybatis生成的代理对象能够存储到IOC容器中的话，就能拿到这个对象做注入。

 <!--Spring整合MyBatis框架-->
  <!-- 加载配置文件 -->
  <context:property-placeholder location="classpath:jdbcConfig.properties" />
  
  <!--配置连接池-->
  <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
    <property name="driverClass" value="${jdbc.driver}"/>
    <property name="jdbcUrl" value="${jdbc.url}"/>
    <property name="user" value="${jdbc.username}"/>
    <property name="password" value="${jdbc.password}"/>
  </bean>

  <!--配置SqlSessionFactory工厂-->
  <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <!-- 加载 mybatis 的全局配置文件 
         添加了mapperScanner  此处可以删除？
    -->
    <property name="configLocation" value="classpath:SqlMapConfig.xml" />
  </bean>

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

Spring整合MyBatis

1.2.5.2、第二步：配置自动扫描所有Mapper接口和文件

1.2.5.3、第三步：配置spring的事务

<!--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"></property>
  </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:method>
    </tx:attributes>
  </tx:advice>
  
  <!--配置AOP增强-->
  <aop:config>
    <!--配置切入点表达式-->
    <aop:pointcut id="pt1" expression="execution(* cn.itcast.service.impl.*ServiceImpl.*(..))"/>
    <aop:advisor advice-ref="txAdvice" pointcut-ref="pt1"/>
  </aop:config>

ApplicationContext中配置事务

1.2.5.4、第三步：测试整合结果

1.2.6、测试SSM整合接管
1.2.6.1、编写测试jsp

1.2.6.2、修改控制器中的方法

1.2.6.3、测试运行结果
