ssm(spring,springmvc,mybatis)

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.xsd
         http://www.springframework.org/schema/aop
         http://www.springframework.org/schema/aop/spring-aop-4.1.xsd
         http://www.springframework.org/schema/tx
         http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
           http://www.springframework.org/schema/context
         http://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>
