Question

使用Eclipse的New-＆gt; Servlet向导，从而为我准备好自动生成的servlet和servlet-mapping条目。但是当我选择一个servlet的java文件并将其删除时，web.xml中的相应条目不会被删除。

我该怎么做？

Answer 1

我想象一下编辑web.xml文件并删除条目。根据设计，删除servlet时不会自动删除它们。

Answer 2

如何使用Annotations？您不必为此在web.xml中处理任何配置。

package com.inventwheel.servlet;

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

/**
 * Servlet implementation class DeleteMe
 */
@WebServlet(description = "DeleteMe Servlet", urlPatterns = { "/DeleteMe" })
public class DeleteMe extends HttpServlet {
    private static final long serialVersionUID = 1L;

    /**
     * @see HttpServlet#HttpServlet()
     */
    public DeleteMe() {
        super();
        // TODO Auto-generated constructor stub
    }

    /**
     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
    }

    /**
     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
    }

}

eclipse使用web.xml条目删除servlet
