《Spring MVC异常友好展示》

Springmvc.xml

配置springmvc.xml，出现exception返回的界面和对应code返回的界面。

不知道为啥httpcode不起作用，网上也没查到相关资料，于是httpcode对应的异常只能用web.xml实现。

    
    <bean id="exceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
         
        <property name="defaultErrorView" value="errorpages/500"/>
        <property name="defaultStatusCode" value="500"/>
        <property name="exceptionAttribute" value="ex"/>
        <property name="warnLogCategory" value="WARN"/>
        
        <property name="exceptionMappings">
           <props>
              
              <prop key="java.lang.RunTimeException">errorpages/500prop> 
              <prop key="java.sql.SQLException">errorpages/500prop>
              <prop key="org.springframework.web.multipart.MaxUploadSizeExceededException">errorpages/upLoadFileErrorprop>  
           props>
        property>
        
        <property name="statusCodes">
           <props>
                 
                 <prop key="errorpages/404">404prop>
                 <prop key="errorpages/404">400prop>
           props>
        property>
    bean>

/errorpages/404.jsp

显示一段时间后自动返回.
