我該如何擺脫：HTTP狀態405 - 此方法不支持HTTP方法GET？

Question

在過去的幾個小時裏，我一直在關注這個問題。這是我第一次嘗試編寫Web應用程序並將其部署到apache tomcat Web容器。我遵循here的簡單教程，然後得到這個錯誤。嘗試了一些解決方案，如其他帖子中關於同一問題的內容，但目前爲止似乎沒有任何解決方案。我正在分別粘貼和web.xml，website.xml和我的代碼文件的片段。請看看我是否做錯了什麼。提前致謝。

web.xml中：

<?xml version="1.0"?> 
<web-app 
    xmlns="http://java.sun.com/xml/ns/j2ee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
     http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" 
    version="2.4"> 
    <servlet> 
     <servlet-name>home</servlet-name> 
     <servlet-class>website.web.TestServlet</servlet-class> 
    </servlet> 
    <servlet-mapping> 
     <servlet-name>home</servlet-name> 
     <url-pattern>/home</url-pattern> 
    </servlet-mapping> 
</web-app> 

website.xml：

<Context path="/website" docBase="C:\Users\Priyankar\workspace\website\web" /> 

HomeServlet.java

package website.web; 

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

public class HomeServlet extends HttpServlet { 

    @Override 
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) 
       throws ServletException, IOException { 
        PrintWriter writer = resp.getWriter(); 
        writer.println("<h1>Hello, World!</h1>"); 
       }   
} 

下面是什麼我看到localhost_access_log：

0:0:0:0:0:0:0:1 - admin [21/Jun/2013:13:25:40 -0500] "POST /manager/html/deploy?org.apache.catalina.filters.CSRF_NONCE=435C56002971030D163AA1C798F91722 HTTP/1.1" 200 14076 
0:0:0:0:0:0:0:1 - - [21/Jun/2013:13:28:50 -0500] "GET /website/home HTTP/1.1" 405 1065 

manager_log：

Jun 21, 2013 1:25:40 PM org.apache.catalina.core.ApplicationContext log 
INFO: HTMLManager: init: Associated with Deployer 'Catalina:type=Deployer,host=localhost'

Jun 21, 2013 1:25:40 PM org.apache.catalina.core.ApplicationContext log 
INFO: HTMLManager: list: Listing contexts for virtual host 'localhost' 

其餘的看似平常的我，除非你想看看在任何特定的日誌文件。

錯誤消息：

下面是從Package Explorer中的項目樹的屏幕截圖：

Answer 1

在你的屏幕截圖中的代碼是一個名爲website.web.TestServlet一個Java類但您的web.xml和代碼發佈說website.web.HomeServlet。

Answer 2

你給的類名是TestServlet，你的web.xml是HomeServlet。所以當你點擊URL時，找不到任何名爲HomeServlet的東西。

稍微偏離主題，但相關：你會部署過程本身，如果你有

<load-on-startup>0</load-on-startup> 

標籤抓住了這個。

這基本上在部署期間加載Servlet，如果它沒有找到任何它會拋出。如果你不給這個標籤，服務器只要感覺就加載。
