Spring MVC异常友好展示

官网

https://docs.spring.io/spring/docs/4.3.25.RELEASE/spring-framework-reference/htmlsingle/

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。

    <!-- 异常友好展示 -->
    <bean id="exceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
        <!-- 默认配置,没有配置的异常或者httpcode返回500,指定异常为ex,前端可以用${ex.message}显示异常信息--> 
        <property name="defaultErrorView" value="errorpages/500"/>
        <property name="defaultStatusCode" value="500"/>
        <property name="exceptionAttribute" value="ex"/>
        <property name="warnLogCategory" value="WARN"/>
        <!-- Exception对应的jsp -->
        <property name="exceptionMappings">
           <props>
              <!-- java.lang.RunTimeException异常返回errorpages/500.jsp页面,其他同理 -->
              <prop key="java.lang.RunTimeException">errorpages/500</prop> 
              <prop key="java.sql.SQLException">errorpages/500</prop>
              <prop key="org.springframework.web.multipart.MaxUploadSizeExceededException">errorpages/upLoadFileError</prop>  
           </props>
        </property>
        <!-- code对应的jsp -->
        <property name="statusCodes">
           <props>
                 <!-- 404对应errorpages/404.jsp -->
                 <prop key="errorpages/404">404</prop>
                 <prop key="errorpages/404">400</prop>
           </props>
        </property>
    </bean>

/errorpages/404.jsp

显示一段时间后自动返回.
