spring.xml

<!-- 加载属性配置文件 -->

    <!-- 开启注解扫描 -->
    <context:component-scan base-package="com.xms"/>
    
    <!-- 开启RequestMapping注解扫描 -->
    <mvc:annotation-driven/>
    
    <!-- 定义视图解析器ViewResolver -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/"/>
        <property name="suffix" value=".jsp"/>

    <!-- 定义MapperScannerrConfigurer扫描组件 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer" >

        <property name="basePackage" value="com.xms.dao" ></property>
        <!-- 手动指定SqlSessionFactory对象 -->  <!-- sqlSessionFactory属性可以不用指定，它会以Autowired方式自动注入 -->

        <!-- 推荐使用注解方法 -->
      <property name="annotationClass" value="com.xms.common.MyAnnontation" ></property> 
    
    <!-- 接口方法 -->
    <!--    <property name="markerInterface" value="com.xms.common.Myinterface" />   -->    
    </bean>

@context:compontent:表示可以在类中使用注解的方式，等价于原有的XML配置中的<bean>定义
