我收到错误

HTTP 状态 404 - /WebServlet3.0/

类型状态报告

消息 /WebServlet3.0/

描述 请求的资源不可用。

Apache Tomcat/7.0.42

这是我的 ServletAsync.java 文件，它位于 src -> com.example.servlet 下

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 ServletAsync
 */

@WebServlet("/ServletAsync")
public class ServletAsync extends HttpServlet {
    private static final long serialVersionUID = 1L;

    /**
     * @see HttpServlet#HttpServlet()
     */
    public ServletAsync() {
        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
    }

}

这是我的 web.xml 文件：

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

</web-app>

这是我的 index.html 文件：

<!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">

</head>
<body>
    <form name="input" action="ServletAsync" method="get">
        Write a text : <input type="text" name="input"> <input
            type="submit" value="Submit">
    </form>
</body>
</html>

问题得到解决。我的项目名称是 webservlet3.0，当我将项目名称更改为 webservlet 时，我的项目开始运行。
