JSP && Servlet | 错误统一处理
对404错误和500错误处理:
在WebContent文件下新建404.jsp 和 500.jsp 显示错误时弹出的信息
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>404</title> </head> <body> 找不到请求路径! </body> </html>
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>500</title> </head> <body> 内部错误! </body> </html>
在web.xml里配置路径:
<error-page> <error-code>500</error-code> <location>/500.jsp</location> </error-page> <error-page> <error-code>404</error-code> <location>/404.jsp</location> </error-page>
重新启动路径即可!
