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.
