發佈請求不在我的servlet中工作，但得到請求確實

我已經創建了一個能夠響應get和post請求的servlet。問題是，當我使用表單發送帖子請求時，我無法回覆。這是代碼。發佈請求不在我的servlet中工作，但得到請求確實

XmlServlet.java：

package org.skiabox.myservlet; 

import javax.servlet.ServletException; 
import javax.servlet.http.HttpServlet; 
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 
import java.io.IOException; 
import java.io.PrintWriter; 


public class XmlServlet extends HttpServlet { 
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 
     response.setContentType("text/html"); 
     PrintWriter out = response.getWriter(); 
     String fullName = request.getParameter("fullName"); 
     String userName = request.getParameter("userName"); 
     out.println("Hello from POST method " + userName + "! We know your full name is " + fullName); 

     String prof = request.getParameter("prof"); 
     out.println("<br/>" + "You are a " + prof); 

    } 

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 
     response.setContentType("text/html"); 
     PrintWriter out = response.getWriter(); 

     String userName = request.getParameter("userName"); 
     out.println("Hello " + userName); 
    } 
}

SimpleForm.html：

<!DOCTYPE html> 
<html> 
<head> 
    <title></title> 
</head> 
<body> 
    <form method="post" action="/XmlServletPath"> 
     User Name:<input name="userName"/> 
     Full Name:<input name="fullName"/> 
     <br/> 
     <br/> 
     Profession: 
     <input type="radio" name="prof" value="Developer">Developer</input> 
     <input type="radio" name="prof" value="Architect">Architect</input> 
     <input type="submit"/> 
    </form> 
</body> 
</html>

Tomcat的設置：

頁輸入詳細信息網址：http://localhost:8080/SimpleServletProject/SimpleForm.html

結果頁面（完全是空的）網址按下提交後： http://localhost:8080/XmlServletPath

您的servlet正在收聽http://localhost:8080/SimpleServletProject/XmlServletPath，而不是http://localhost:8080/XmlServletPath。您的表單提交給錯誤的網址。

只需相應地修復表單操作URL即可。更換

<form method="post" action="/XmlServletPath">

通過

<form method="post" action="/SimpleServletProject/XmlServletPath">

，或者，如果提交表單的頁面是在同一個URL文件夾嗎

<form method="post" action="XmlServletPath">

，或者，如果你擔心上下文路徑的動態性

<form method="post" action="${pageContext.request.contextPath}/XmlServletPath">

這是我第一次嘗試b如果它失敗了。現在我再次嘗試它可以工作。也許我輸入了錯誤的東西。無論如何謝謝你的回答！ – skiabox 2013-03-20 18:44:44

不客氣。 – BalusC 2013-03-20 18:48:00

實際上，我正在學習本教程（https://www.youtube.com/watch?v=MnUJl3NYRRc&list=PLE0F6C1917A427E96），並且該人員通過使用簡單/ XmlServletPath作爲操作參數而不是完整路徑來管理相同的結果，但他使用另一個IDE（Eclipse）。 – skiabox 2013-03-20 18:48:30
