设置常用错误页面自定义显示

web.xml根结点下增加

 1     <error-page>
 2         <error-code>400</error-code>
 3         <location>/WEB-INF/jsp/error/400.jsp</location>
 4     </error-page>
 5     <error-page>
 6         <error-code>404</error-code>
 7         <location>/WEB-INF/jsp/error/404.jsp</location>
 8     </error-page>
 9     <error-page>
10         <error-code>406</error-code>
11         <location>/WEB-INF/jsp/error/406.jsp</location>
12     </error-page>
13 
14     <error-page>
15         <exception-type>java.lang.Throwable</exception-type>
16         <location>/WEB-INF/jsp/error/500.jsp</location>
17     </error-page>

编写相应的错误文件（以500.jsp错误为例）

 1 <!-- 
 2 isErrorPage="true"必须设置，不然无法获取异常信息；
 3  -->
 4 <%@ page language="java" contentType="text/html; charset=UTF-8"
 5     isErrorPage="true" pageEncoding="UTF-8"%>
 6 <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
 7 <%
 8     response.setStatus(HttpServletResponse.SC_OK); //这句也一定要写,不然IE不会跳转到该页面
 9     String path = request.getContextPath();
10 %>
