// 设置响应编码
resp.setCharacterEncoding("UTF-8");
resp.setContentType("text/html;charset=utf-8");

package com.example.demo.learn.servlet;

import org.apache.commons.lang3.time.DateFormatUtils;

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 java.io.IOException;
import java.io.PrintWriter;
import java.util.Date;

@WebServlet("/HelloServlet")
public class HelloServlet extends HttpServlet {

    @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 {
        // 设置响应编码
        resp.setCharacterEncoding("UTF-8");
        resp.setContentType("text/html;charset=utf-8");

        String code = req.getParameter("code");
        code = "您请求的数据: " + code + ", 当前时间: " + DateFormatUtils.format(new Date(), "yyyy-MM-dd HH:mm:ss");

        PrintWriter out = resp.getWriter();
        out.write(code);
        out.close();
    }
}
