Question

整个上午我都遇到了这个问题，我似乎无法理解为什么。

这是我的servlet。很简单：

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

    /**
     * @see HttpServlet#HttpServlet()
     */
    public hello() {
        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
        response.getWriter().write("test");
    }

    /**
     * @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);
    }

}

当我启动tomcat服务器并转到http://localhost:8080/testh/hello时，收到错误消息： HTTP状态404 - / testh / hello

为什么呢？服务器已启动，我在项目＆＃34; testh＆＃34;下运行了这个特定的servlet / hello。我不明白。请帮忙。

Answer 1

尝试拨打http://localhost:8080/hello

因为你所有的项目都在根

之下

/

然后你有映射/hello

此外，如果您确切需要http://localhost:8080/testh/hello，则应使用路径 / testh 部署应用，然后HTTP调用将路由到 / testh / hello ，因为您的servlet路径是 / hello +应用路径 / testh

404所请求的资源在非常简单的servlet上不可用
