java web 自定义错误页面 完整jsp错误页面代码（同时写错误日志） error.jsp

web.xml的配置很简单啦，网上搜一下就一大堆了。

<error-page>
        <error-code>500</error-code>
        <location>/error.jsp</location>
 </error-page>

这里分享一下自己刚完成的自定义错误页面error.jsp，高度可用~~~欢迎提出问题指正~~

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@page isErrorPage="true" %>
<%@page import="java.text.SimpleDateFormat"%>
<%@ page import="java.io.*"%>
<%
    response.setStatus(HttpServletResponse.SC_OK);
%>
