Spring MVC学习笔记（3）---整合MyBatis

1、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>

</configuration>

2、mapper接口和mapper.xml由mybatis逆向工程生成

3、applicationContext.xml，配置数据源、配置SqlSessionFactory、mapper扫描器

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
	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-4.0.xsd
	http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
	http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
	http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">

	<!-- 加载配置文件 -->
	<context:property-placeholder location="classpath:db.properties" />

	<!-- 数据库连接池 -->
	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
		destroy-method="close">
		<property name="driverClassName" value="${jdbc.driver}" />
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
		<property name="maxActive" value="10" />
		<property name="maxIdle" value="5" />
	</bean>

	<!-- 配置sqlSessionFactory -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<!-- 数据库连接池 -->
		<property name="dataSource" ref="dataSource" />
		<!-- 加载mybatis的全局配置文件 -->
		<property name="configLocation" value="classpath:sqlMapConfig.xml" />
	</bean>

	<!-- 配置Mapper扫描 -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<!-- 配置Mapper扫描包 -->
		<property name="basePackage" value="com.iteason.mapper" />
	</bean>

    <!--配置spring注解扫描--!>
   <context:component-scan base-package="com.iteason" />

    <!-- 配置事务 -->
		<bean id="transactionManager"                 class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
			<property name="dataSource" ref="dataSource"/>
		</bean>
		
		<!-- 开启注解事务 -->
		<tx:annotation-driven transaction-manager="transactionManager"/>
</beans>

4、配置springmvc.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:p="http://www.springframework.org/schema/p"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">

	<!-- 配置controller扫描包 -->
	<context:component-scan base-package="com.iteason.controller" />

	<!-- 注解驱动 -->
	<mvc:annotation-driven />

	<!-- Example: prefix="/WEB-INF/jsp/", suffix=".jsp", viewname="test" -> 
		"/WEB-INF/jsp/test.jsp" -->
	<!-- 配置视图解析器 -->
	<bean
	class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<!-- 配置逻辑视图的前缀 -->
		<property name="prefix" value="/WEB-INF/jsp/" />
		<!-- 配置逻辑视图的后缀 -->
		<property name="suffix" value=".jsp" />
	</bean>

</beans>

5、配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://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" id="WebApp_ID" version="2.5">
  <display-name>springMVC_day1</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spring -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:applicationContext.xml</param-value>
	</context-param>

	<!-- 使用监听器加载Spring配置文件 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	
	
  <!-- 配置前端控制器 -->
  <servlet>
  	<servlet-name>springmvc</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>springmvc</servlet-name>
  	<url-pattern>*.action</url-pattern>
  </servlet-mapping>
  
  <!-- 解决post乱码问题 -->
	<filter>
		<filter-name>encoding</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<!-- 设置编码参是UTF8 -->
		<init-param>
			<param-name>encoding</param-name>
			<param-value>UTF-8</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>encoding</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
  
  
</web-app>
