為什么使用eclipse總是出現(xiàn)404
index里面
<%@ page language="java" contentType="text/html; charset=utf-8"
? ? pageEncoding="utf-8"%>
<!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">
<title>Insert title here</title>
</head>
<body>
<a href="Helloservlet">你好</a>
<form action="/Helloservlet" method="post">
<input type="submit" value="很好"/>
</form>
</body>
</html>
Helloservlet里面的代碼如下，沒有配置web.xml因為已經(jīng)有了注解
package servlet;
import java.io.IOException;
import java.io.PrintWriter;
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 Helloservlet
?*/
@WebServlet("/Helloservlet")
public class Helloservlet extends HttpServlet {
private static final long serialVersionUID = 1L;
? ? /**
? ? ?* Default constructor.?
? ? ?*/
? ? public Helloservlet() {
? ? ? ? // 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
doPost(request, response);
response.getWriter().append("Served at: ").append(request.getContextPath());
System.out.println("很好");
PrintWriter out=response.getWriter();
response.setContentType("text/html;charset=utf-8");
out.println("<strong>xixi</strong>");
}
/**
* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
doGet(request, response);
System.out.println("很好");
PrintWriter out=response.getWriter();
response.setContentType("text/html;charset=utf-8");
out.println("<strong>xixi</strong>");
}
}
但是一直出現(xiàn)以下問題，已經(jīng)一個消失了都沒有解決成功，求大神來解答

我的是xml文件中<url-pattern>/Servlet/HelloServlet</url-pattern>的Servlet首字母是小寫，改成大寫就OK了

路徑出錯,其實你應該直接訪問頁面,而不是訪問servlet
