生活随笔收集整理的這篇文章主要介紹了 struts2访问jsp页面404 小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.

問題描述

在搭建struts2環(huán)境的時候，拷貝了web.xml，拷貝了struts.xml，拷貝了jar包。運(yùn)行，正常，訪問jsp頁面，報(bào)404錯誤。

web.xml

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://xmlns.jcp.org/xml/ns/javaee"xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"id="WebApp_ID" version="3.1"><display-name>hellostruts2</display-name><filter><filter-name>struts</filter-name><filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class></filter><filter-mapping><filter-name>struts</filter-name><url-pattern>/*</url-pattern></filter-mapping></web-app>

struts.xml

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN""http://struts.apache.org/dtds/struts-2.0.dtd"> <struts><package name="xxxx" extends="struts-default"><action name="hello" class="com.zengmg.strtus.HelloAction" method="execute"><result name="success">/success.jsp</result></action></package></struts>

訪問：

http://localhost:8080/strutsfiledemo/success.jsp。報(bào) 404！

原因：

因?yàn)閟truts.xml配置了的action沒有java類與其對應(yīng)，所以報(bào)錯。但是我沒把控制臺的信息拉到上面看，導(dǎo)致沒看到信息。
