3. java实现：类名：TestServlet

 

package com.dahantc.test;

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 org.slf4j.Logger;
import org.slf4j.LoggerFactory;
@WebServlet("/TestServlet")
public class TestServlet extends HttpServlet {

	private static Logger logger = LoggerFactory.getLogger(TestServlet.class);
	private static final long serialVersionUID = -6795168385294556128L;

	@Override
	protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
		doPost(req, resp);
	}

	@Override
	protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
		logger.info("===============sss进入==============");
		PrintWriter _write = resp.getWriter();
		_write.print("22");
		_write.flush();
		_write.close();
		logger.info("========end=======");
	}

}
