Question

我用struts框架编写了一个jsp页面。在运行时我遇到了404错误。

的Login.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
     <%@ taglib prefix="s" uri="/struts-tags"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<s:form action="login" method="post">  
<s:textfield name="id" label="Employee Id"></s:textfield>  
<s:textfield name="name" label="Employee Name"></s:textfield>
<s:submit value="submit"></s:submit>   
</s:form>
</body>
</html>

LoginAction.java

package Login;

public class LoginAction {
    private int id;  
    private String name;  

    public int getId() {  
        return id;  
    }  

    public String getName() {  
   return name;  
    }  

    public String execute(){  
        return "success"; 
}
}

struts.xml中：

<?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>
<constant name="struts.devMode" value="true" />
   <package name="Login" extends="struts-default" namespace="/" >
   <default-action-ref name="upload" />


      <action name="login"  class="Login.LoginAction" method="execute">  
<result name="success">products.jsp</result>  
</action>  


   </package>
</struts>

的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>Product</display-name>



   <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>/*</url-pattern>
   </filter-mapping>



     <welcome-file-list>
  <welcome-file>Login.jsp</welcome-file>
  </welcome-file-list>
   </web-app>

products.jsp：

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
    <%@ taglib prefix="s" uri="/struts-tags"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>product images</title>

</head>
<body>
<a href="productdetails.jsp"><img src="images/bp.jpg" class="tooltip" title="BP monitor" id="BP monitor"> </a>
<a href="productdetails.jsp"><img src="images/sethescope.jpg" class="tooltip" title="sethescope" id="sethescope"></a>


    </body>
</html>

项目浏览器：结果：

Answer 1

您的网址应为http://localhost:8080/webapp/products 您缺少webapp部分，这是您的war文件名。

Answer 2

拉吉，您需要在URL中使用正确的区分大小写的上下文路径（默认情况下为war文件名）。如果您的背景是＆＃39;产品＆＃39;尝试localhost：8080 /产品

同时在http://tomcat.apache.org/tomcat-6.0-doc/config/context.html#Introduction
