SpringMVC 【<mvc:annotation-driven />】 到底做了什么工作

一句 <mvc:annotation-driven />实际做了以下工作：（不包括添加自己定义的拦截器）

我们了解这些之后，对Spring3 MVC的控制力就更强大了，想改哪就改

<!-- 注解请求映射  -->
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">        
        <property name="interceptors">
            <list>  
                <ref bean="logNDCInteceptor"/>   <!-- 日志拦截器，这是你自定义的拦截器 -->
                <ref bean="myRequestHelperInteceptor"/>   <!-- RequestHelper拦截器，这是你自定义的拦截器--> 
                <ref bean="myPermissionsInteceptor"/>  <!-- 权限拦截器，这是你自定义的拦截器--> 
                <ref bean="myUserInfoInteceptor"/>  <!-- 用户信息拦截器，这是你自定义的拦截器--> 
            </list>        
        </property>        
</bean>      
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
        <property name="messageConverters">  
            <list>  
                <ref bean="byteArray_hmc" />  
                <ref bean="string_hmc" />  
                <ref bean="resource_hmc" />  
                <ref bean="source_hmc" />  
                <ref bean="xmlAwareForm_hmc" />  
                <ref bean="jaxb2RootElement_hmc" />  
                <ref bean="jackson_hmc" />  
            </list>  
        </property>  
</bean>
