springmvc中的ssm

- 1.引入框架（其实就是放jar包)
spring+springMVC(3个)+mybaits(3个)

- 2.编写spring-config.xml主配置文件
- 2.1.编写专门处理数据连接池的配置文件spring-db.xml

<!-- 数据连接池 -->    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"        init-method="init" destroy-method="close">        <property name="jdbcUrl" value="${jdbc.url}" />        <property name="user" value="${jdbc.user}" />        <property name="password" value="${jdbc.password}" />    </bean>    <bean name="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">        <property name="dataSource" ref="dataSource"></property>        <property name="mapperLocations" value="classpath:com/ruicaiedu/ssm/mapper/*.xml"></property>        <property name="typeAliasesPackage" value="com.ruicaiedu.ssm.entity"></property>    </bean>    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">        <property name="basePackage" value="com.ruicaiedu.ssm.mapper" /><!--             要打描的接口类所在的包 -->        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />    </bean>

• 2.2.编写专门处理事务的配置文件spring-transaction.xml

    <bean name="transactionManager"        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">        <property name="dataSource" ref="dataSource"></property>    </bean>    <tx:annotation-driven transaction-manager="transactionManager" />

• 2.3.编写专门处理mvc的配置文件sring-mvc.xml

 <mvc:annotation-driven />    <bean        class="org.springframework.web.servlet.view.InternalResourceViewResolver">        <property name="prefix" value="/" />        <property name="suffix" value=".jsp" />    </bean>

然后主配置文件导入其它三个配置文件

 <import resource="/WEB-INF/spring-db.xml" />   <import resource="/WEB-INF/spring-transaction.xml" />  <import resource="/WEB-INF/spring-mvc.xml" />

• 3.在web.xml文件中引入spring-config.xml主配置文件
  
  • 3.1引入spring-config

<context-param>        <param-name>contextConfigLocation</param-name>        <param-value>/WEB-INF/spring-config.xml</param-value>    </context-param>    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>

• 3.2让springmvc来管理整个web控制层

  <servlet>        <servlet-name>Dispatcher</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>        <init-param>            <param-name>contextConfigLocation</param-name>            <param-value>/WEB-INF/spring-config.xml</param-value>        </init-param>    </servlet>    <servlet-mapping>        <servlet-name>Dispatcher</servlet-name>        <url-pattern>*.do</url-pattern>    </servlet-mapping>

• 4..开始编写代码
