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

1、首先配置web.xml  添加一下代码

 

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

 

 

2、error.jsp页面

<%@ 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);
%>

try {
//全部内容先写到内存,然后分别从两个输出流再输出到页面和文件
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
PrintStream printStream = new PrintStream(byteArrayOutputStream);

printStream.println();
printStream.println("用户信息");
printStream.println("账号:" + request.getSession().getAttribute("userName"));

}
printStream.println();
}

}
String timeStamp = new SimpleDateFormat("yyyyMMddhhmmssS").format(new Date());
FileOutputStream fileOutputStream = new FileOutputStream(new File(dir.getAbsolutePath() + File.separatorChar + "error-" + timeStamp + ".txt"));
new PrintStream(fileOutputStream).print(byteArrayOutputStream); //写到文件

} catch (Exception ex) {
ex.printStackTrace();
}
