【JSP开发】通过response的writer流输出数据的问题

package cn.edu.Response;

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;

//通过response的writer流输出数据的问题
public class ResponseDemo2 extends HttpServlet {

public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

text1(response);

}

private void text1(HttpServletResponse response) throws IOException {
//设置response使用的码表，以控制response以什么码表向浏览器写出数据
response.setCharacterEncoding("UTF-8");

//指定浏览器以什么码表打开浏览器发送的数据
//response.setHeader("content-type", "text/html;charset=UTF-8");
response.setContentType("text/html;charset=UTF-8");
//上面那句话间接的包含了setCharacterEncoding("UTF-8");
String data="中国";

PrintWriter out =response.getWriter();
//writer流只能写字符或者字符串（写字节流的东西不行）
out.write(data);
}

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request,response);
}

}
