servlet-3.0 - WebServlet urlPatterns 给出 404 错误

Question

我试图使用 servlet Annotation 。

这是我的 servlet，如下所示，上下文名称是Teste 我的项目中没有任何 web.xml。

package com;
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;
import javax.servlet.http.HttpSession;
@WebServlet(name = "Mine", urlPatterns = { "/Mine" })
public class Mine extends HttpServlet {
    private static final long serialVersionUID = 1L;
    public Mine() {
        super();
        System.out.println("I am Called");
    }

    protected void doGet(HttpServletRequest request,
            HttpServletResponse response) throws ServletException, IOException {
        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
        HttpSession session = request.getSession(true);
        String str = (String) session.getAttribute("salary");
        out.println("str is" + str);
    }
}

尝试在浏览器中访问时出现错误 404

请让我知道我在哪里做错了。
