1.配置web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"><display-name>ssm</display-name><!-- 1.针对Spring配置：读取配置文件 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></context-param><!-- 注册ServletContext监听器，创建容器对象，并且将ApplicationContext对象放到Application域中 --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 针对SpringMVC的配置：中央调度器：本质上一个serlvet 配置的关于SpringmVC组件 --><servlet><servlet-name>springmvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!-- 管理参数类的配置 --><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>springmvc</servlet-name><url-pattern>*.do</url-pattern></servlet-mapping><!-- 解决乱码的过滤器 --><filter><filter-name>CharacterEncodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><!-- 请求编码 --><init-param><param-name>encoding</param-name><param-value>utf-8</param-value></init-param><!-- 响应编码 --><init-param><param-name>forceEncoding</param-name><param-value>true</param-value></init-param></filter><filter-mapping><filter-name>CharacterEncodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list> </web-app>
2.搭建分层
UserInfoDAO.xml代码
<?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="cn.cnsdhzzl.dao.IUserInfoDAO"><select id="add" parameterType="UserInfo">insert into userinfo values(SEQ_SSM.nextval,#{name},#{age})</select> </mapper>
3.配置applicationContext.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:p="http://www.springframework.org/schema/p"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop-4.1.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-4.1.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-4.1.xsd "><!-- 01.配置数据源 --><bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"><property name="driverClass" value="${jdbc.driver}"></property><property name="jdbcUrl" value="${jdbc.url}"></property><property name="user" value="${jdbc.name}"></property><property name="password" value="${jdbc.password}"></property></bean><!-- 1.1 关联jdbc.properties --><context:property-placeholder location="classpath:jdbc.properties" /><!-- 02.配置SessionFactory --><bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="configLocation" value="classpath:mybatis-config.xml"></property><property name="dataSource" ref="dataSource"></property></bean><!-- 03.生成dao代理對象 --><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="sqlSessionFactoryBeanName" value="sessionFactory"></property><property name="basePackage" value="cn.cnsdhzzl.dao"></property></bean><!--04.配置service --><bean id="userService" class="cn.cnsdhzzl.service.impl.IUserInfoServiceImpl"><property name="dao" ref="IUserInfoDAO"></property></bean><!-- 05.配置action --><bean id="/saveUser.do" class="cn.cnsdhzzl.controller.IUserInfoController"><property name="service" ref="userService"></property></bean><!-- 06.配置事务管理器 --><bean id="transactionManager"class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource"></property></bean><!-- 07.配置开启事务操作 --><tx:advice id="txAdvice" transaction-manager="transactionManager"><tx:attributes><!--指定在连接方法上应用的事务属性 --><tx:method name="add*" isolation="DEFAULT" propagation="REQUIRED" /></tx:attributes></tx:advice><!-- aop配置 --><aop:config><aop:pointcut expression="execution(* *..service.*.*(..))"id="stockPointcut" /><aop:advisor advice-ref="txAdvice" pointcut-ref="stockPointcut" /></aop:config></beans>
