        ServletContextHandler context = new ServletContextHandler();
        context.setContextPath("/");
        context.addServlet(LoginServlet.class, "/LoginServlet");
        
        HandlerCollection handlers = new HandlerCollection();
        handlers.setHandlers(new Handler[] { context, new DefaultHandler() });
        server.setHandler(handlers);
        
        server.start();
        server.join();

LoginServlet.java

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@WebServlet("/LoginServlet")
public class LoginServlet extends HttpServlet {
	private static final long serialVersionUID = 1L;
       
    public LoginServlet() {
        super();
    }
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		response.setContentType("text/json;charset=utf-8");
		response.setCharacterEncoding("utf-8");
		response.getWriter().write("{result:\"返回数据成功！\"}");
	}
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
	}

}
