我收到错误

HTTP 状态 404 -/WebServlet3.0/

<小时/>

输入状态报告

消息/WebServlet3.0/

描述请求的资源不可用。

<小时/>

Apache Tomcat/7.0.42

这是我的 ServletAsync.java 文件,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:

</web-app>

这是我的index.html 文件:

<body>
<form name="input" action="ServletAsync" method="get">
Write a text : <input type="text" name="input"> <input

您能解决我的问题吗?为什么我会收到此错误以及如何解决它?我只想显示网页。

最佳答案

问题已解决。我的项目名称是webservlet3.0,当我将项目名称更改为webservlet时,我的项目就开始运行了。
