Java Web中乱码问题

Posted 2020-08-09

response.setContentType("text/html;charset=UTF-8");

用于定义网络文件的类型和网页的编码，决定浏览器将以什么形式、什么编码读取这个文件

package cn.edu.aynu.rjxy.servlet;

import java.io.IOException;
import java.io.PrintWriter;

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

public class BServlet extends HttpServlet {

    /*
     * 乱码
     * */
    public void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        //设置编码为UTF-8格式
        response.setContentType("text/html;charset=UTF-8");
        //创建out对象
        PrintWriter out = response.getWriter();
        //输出语句
        out.println("今天是9月21号");
        //手动刷新
        out.flush();
        //关闭流
        out.close();
    }

}
