There are two ways to handle error pages in Tomcat.<\/p>\n

    \n
  1. Setting error pages using web.xml: In the web.xml file, you can configure global error pages as well as error pages corresponding to specific error codes. For example:<\/li>\n<\/ol>\n
    <error-page<\/span>><\/span>\r\n    <error-code<\/span>><\/span>404<\/error-code<\/span>><\/span>\r\n    <location<\/span>><\/span>\/error\/404.html<\/location<\/span>><\/span>\r\n<\/error-page<\/span>><\/span>\r\n<error-page<\/span>><\/span>\r\n    <error-code<\/span>><\/span>500<\/error-code<\/span>><\/span>\r\n    <location<\/span>><\/span>\/error\/500.html<\/location<\/span>><\/span>\r\n<\/error-page<\/span>><\/span>\r\n<\/code><\/pre>\n
      \n
    1. Using Servlet to handle error pages: You can customize a Servlet to handle error pages by implementing the javax.servlet.ErrorPage interface, to handle various error page scenarios. For example:<\/li>\n<\/ol>\n
      @WebServlet(\"\/errorHandler\")<\/span>\r\npublic<\/span> class<\/span> ErrorHandlerServlet<\/span> extends<\/span> HttpServlet<\/span> implements<\/span> ErrorPage<\/span> {\r\n\r\n    @Override<\/span>\r\n    public<\/span> void<\/span> handleErrorPage<\/span>(HttpServletRequest request, HttpServletResponse response)<\/span> {\r\n        \/\/ \u5904\u7406\u9519\u8bef\u9875\u9762\u903b\u8f91<\/span>\r\n        response.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);\r\n        response.setContentType(\"text\/html\"<\/span>);\r\n        PrintWriter<\/span> out<\/span> =<\/span> response.getWriter();\r\n        out.println(\"<html><body>\"<\/span>);\r\n        out.println(\"<h1>Internal Server Error<\/h1>\"<\/span>);\r\n        out.println(\"<p>Sorry, something went wrong.<\/p>\"<\/span>);\r\n        out.println(\"<\/body><\/html>\"<\/span>);\r\n    }\r\n}\r\n<\/code><\/pre>\n
      It is important to note that the above methods all require configuring the mapping relationship of the Servlet in web.xml or implementing the javax.servlet.ServletContainerInitializer interface, as well as handling error page logic in the Servlet.<\/p>\n","protected":false},"excerpt":{"rendered":"
