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.
