SSM整合

 1.spring的配置文件.
       <!-- 包扫描 -->
   <context:component-scan base-package="com.zhiyou.ykq"/>
   
   <!-- 引入属性文件. -->
   <context:property-placeholder location="classpath:db.properties"/>
   
   <!-- 定义数据源c3p0 -->
   <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
       <property name="user" value="${jdbc.username}"/>
       <property name="password" value="${jdbc.password}"/>
       <property name="jdbcUrl" value="${jdbc.url}"/>
       <property name="driverClass" value="${jdbc.driverClass}"/>
   </bean>
   
   <!-- 定义一个SessionFactory工程类的bean  把mybatis配置文件中内容 放该类中 -->
   <bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <!-- 为该包下的实体类起别名 -->
        <property name="typeAliasesPackage" value="com.zhiyou.ykq.bean"/>
        <!-- 加载mybatis的映射文件 -->
        <property name="mapperLocations" value="classpath:com/zhiyou/ykq/mapper/*.xml"/>
   </bean>
   
   <!-- 配置mybatis接口的实现类  usersDao=session.getMapper(UsersDao.class);//相当于你创建了一个Dao对象 -->
   <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
       <!-- basePackage:表示哪些包下的接口 要生产实现类 -->
       <property name="basePackage" value="com.zhiyou.ykq.dao"/>
       <property name="sqlSessionFactory" ref="sessionFactory"/>
   </bean>
    
   <!-- 事物管理 -->
   <bean id="tm" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
       <property name="dataSource" ref="dataSource"/>
   </bean>
   
   <!-- 方法的属性 -->
   <tx:advice transaction-manager="tm" id="advice">
       <tx:attributes>
          <tx:method name="query*" read-only="true"/>
          <tx:method name="find*" read-only="true"/>
          <tx:method name="get*" read-only="true"/>
          <tx:method name="select*" read-only="true"/>
          <tx:method name="*"/>
       </tx:attributes>
   </tx:advice>
   
   <!-- 切面的配置 -->
   <aop:config>
       <aop:pointcut expression="execution(* com.zhiyou.ykq.service.*.*(..))" id="pointcut"/>
       <aop:advisor advice-ref="advice" pointcut-ref="pointcut"/>
   </aop:config>
 
 
   2.springmvc的配置文件。
      <!-- 包扫描 -->
   <context:component-scan base-package="com.zhiyou.ykq.controller"/>
   
   <!-- 开启注解 -->
   <mvc:annotation-driven/>
   
   <!-- 静态资源 -->
   <mvc:default-servlet-handler/>
   
   
   <!-- 视图解析器 -->
   <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
       <property name="prefix" value="/"/>
       <property name="suffix" value=".jsp"/>
   </bean>
   
   3.web.xml文件.
   
   <!-- 加载springmvc的配置文件 -->
    <servlet>
        <servlet-name>springDispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>springDispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    

     <!-- 指定spring的配置文件的路径 -->
   <context-param>
       <param-name>contextConfigLocation</param-name>
       <param-value>classpath:applicationContext.xml</param-value>
   </context-param>
 
    <listener>
        <!-- 默认加载的配置文件为WEB-INF/applicationContext.xml -->
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
