stucts2中错误找不到文件路径

可能性：

structs.xml 文件（文件名一个字母都不能出错）应该放在 src文件夹下面。具体配置如下：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN""http://struts.apache.org/dtds/struts-2.3.dtd"><!-- START SNIPPET: xworkSample -->
<struts><!-- extends必须写，直接或者间接继承struts-default name自定义 --><package name="struts" extends="struts-default"><!-- name是请求名称，不要写/;class对应action完全限定名=包名+类名   method: 指定处理类所触发的方法 --><action name="test" class="com.wang.struts2.Test"><!-- result是结果集  name和对应action中的方法的返回值匹配，默认是success --><result name="success">/MyJsp.jsp</result></action></package>
</struts>

配置中的extends="struts-default" 必须写不能错（当然也可以间接继承）

web.xml(在WEB-INF文件夹下) <filter-name>struts2</filter-name> 这个不能写错切记勿写成structs2

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"><filter><filter-name>struts2</filter-name><filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class></filter><filter-mapping><filter-name>struts2</filter-name><url-pattern>*.action</url-pattern></filter-mapping><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list>
</web-app>

处理类（此处不多说）

package com.wang.struts2;import com.opensymphony.xwork2.Action;public class Test {public String execute(){System.out.println("hello Test");return Action.SUCCESS;}
}
