Simple configuration of the Java Web Engineering error page

JSP page, itself the server will also translate the page into a servlet page, so the request for the page is likely to be wrong, there will be a page similar to the following

This is not friendly to the customer.

1. JSP page <%@ The ErrorPage attribute in the page%> directive

You can configure the ErrorPage property in the <%@ page%> directive in the JSP page, and when an error occurs accessing this page, it jumps to the configured friendly page

<%@ Page Language="Java"Import="java.util.*"pageencoding="UTF-8" errorpage="errorpage.jsp" %>

Jump to the error page ... It looks a lot better then.

2. Configure Web. xml

In the Java Web project, you can also configure a global error page configuration for the. XML configuration file, so that errors occur in the project and will jump to the appropriate page.

<!--Global error Handling page configuration -  <Error-page>        <!--when a server error occurs -      <Error-code>500</Error-code>      < Location>/errorpage.jsp</ Location>  </Error-page>  <Error-page>       <!--resources not found -      <Error-code>404</Error-code>      < Location>/404.html</ Location>  </Error-page>

When configured, the page is not found, or the resource access does not exist

Note:

　When the ErrorPage attribute is configured in the JSP, the page error ignores the <error-code>500</error-code> configuration (nearest principle) in Web. Xml. You can configure the special processing page on which a page error occurs based on this
