No action config found for the specified url

　　url路径下找不到action，原因是stuts-config.xml文件配置错误。

　　demo的项目文件如下：

org.apache.struts.chain.commands.InvalidPathException: No action config found for the specified url.

　　使用jsp文件夹中的login.jsp文件调用action：

<%@ page language="java" contentType="text/html"

    pageEncoding="GBK"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<title>用户登录</title>

</head>

<body>

    <!-- 标准登录框 -->

    <div id="Login_LoginForm">

        <div>账号登录</div>

        <form method="post" action="loginng.do">

                账号：<input name="username" type="text">

                密码：<input name="password" type="password">

                <a target="_blank" href="register.jsp">免费注册</a>

                <input type="submit" value="登录">

                <input type="reset" value="重新输入">

        </form>

    </div>

</body>

</html>

　　web.xml配置文件如下:

<?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>StrutsSample</display-name>

  <servlet>

      <servlet-name>action</servlet-name>

      <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>

      <init-param>

          <param-name>config</param-name>

          <param-value>/WEB-INF/struts-config.xml</param-value>

      </init-param>

      <load-on-startup>1</load-on-startup>

  </servlet>

  <servlet-mapping>

      <servlet-name>action</servlet-name>

      <url-pattern>*.do</url-pattern>

  </servlet-mapping>

  <welcome-file-list>

    <welcome-file>index.html</welcome-file>

    <welcome-file>index.htm</welcome-file>

    <welcome-file>index.jsp</welcome-file>

    <welcome-file>default.html</welcome-file>

    <welcome-file>default.htm</welcome-file>

    <welcome-file>default.jsp</welcome-file>

  </welcome-file-list>

</web-app>

　　struts-config.xml配置文件如下：

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE struts-config PUBLIC

          "-//Apache Software Foundation//DTD Struts Configuration 1.3//EN"

          "http://struts.apache.org/dtds/struts-config_1_3.dtd">

<struts-config>

    <form-beans>

        <form-bean name="loginForm"

            type="org.sunnywen.struts.LoginActionForm">

        </form-bean>

    </form-beans>

    <action-mappings>

        <action path="/loginng"

            name="loginForm"

            type="org.sunnywen.struts.LoginAction">

            <forward name="loginSuccess" path="/index.jsp"></forward>

        </action>

    </action-mappings>

</struts-config>

　　LoginActionForm是继承ActionForm的类，LoginAction是继承Action的类，此时运行将会出现错误：org.apache.struts.chain.commands.InvalidPathException: No action config found for the specified url.

　　原因是JSP文件是在jsp文件夹中，action="loginng.do"会自动去寻找同一文件夹下（即jsp文件夹）的loginng.do，而在struts-config.xml中配置的action的path是配置在根目录下，所以应当如下进行配置：

<action-mappings>

        <action path="/jsp/loginng"

            name="loginForm"

            type="org.sunnywen.struts.LoginAction">

            <forward name="loginSuccess" path="/index.jsp"></forward>

        </action>

    </action-mappings>
