    <!--第一步，扫描service-->
        <context:component-scan base-package="com.zmh.ssm.service.impl"></context:component-scan>
        <!--第二步，加载jdbc.properties-->
        <context:property-placeholder location="classpath:jdbc.properties"></context:property-placeholder>
        <!--第三步，创建dbcp数据源连接池-->
        <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">

            <!--指定数据源-->
            <property name="dataSource" ref="dataSource"></property>
            <!--加载mybatis的映射文件  在value中可以使用*号通配符-->
            <property name="mapperLocations" value="classpath:mapper/*.xml"></property>
        </bean>
        <!--第五步，在spring的工厂中生成dao接口的实现类对象-->
        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
            <!--指定要扫描哪个包下面所有的dao接口-->
            <property name="basePackage" value="com.zmh.ssm.dao"></property>
        </bean>
        <!--第六步，创建spring的事物管理器-->
        <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
            <property name="dataSource" ref="dataSource"></property>
        </bean>
        <!--第七步，声明以注解的方式配置声明式事物-->
        <tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven>
</beans>

2、spring-mvc主配置文件

 <?xml version="1.0" encoding="UTF-8"?>

     <!--扫描控制器包-->
     <context:component-scan base-package="com.zmh.ssm.controller"></context:component-scan>
         <!--声明以注解的方式配置spring mvc 相当于配置类
             RequestMappingHandlerMapping   处理器映射器
             RequestMappingHandlerAdapter   处理器适配器
         -->
         <mvc:annotation-driven></mvc:annotation-driven>
         <!--配置spring mvc默认的jsp视图解析器-->
         <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
             <!--配置返回视图的前缀-->
             <property name="prefix" value="/WEB-INF/jsp/"></property>
             <!--配置返回视图的后缀-->
             <property name="suffix" value=".jsp"></property>
         </bean>
 </beans>

3、web.xml配置文件

     <context-param>
         <param-name>contextConfigLocation</param-name>

         <servlet-name>spring-mvc</servlet-name>
         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
         <!--指定spring mvc的主配置文件的位置和名称-->
         <init-param>
             <param-name>contextConfigLocation</param-name>
             <param-value>classpath:spring-mvc.xml</param-value>

     </filter>
     <filter-mapping>
         <filter-name>characterEncodingFilter</filter-name>
         <url-pattern>/*</url-pattern>
     </filter-mapping>
 </web-app>
