【JSP开发】response输出中文和数据的问题

package cn.edu.Response;


import java.io.IOException;
import java.io.OutputStream; 
import java.io.PrintWriter;
import java.io.UnsupportedEncodingException;


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


//servlet中用OutputStream输出中文和数据的问题
public class ResponseDemo1 extends HttpServlet {




	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		
		test2(response);
	}


	private void test1(HttpServletResponse response) throws IOException,
			UnsupportedEncodingException {
		//程序以什么码表输出了，程序就一定要控制浏览器以什么码表打开
		//text/html;如果写成text/html,的话浏览器会提示下载
		response.setHeader("Content-type", "text/html;charset=UTF-8");
        String data="中国";
        
        ServletOutputStream out =response.getOutputStream(); 
        //浏览器默认的字节编码是gb2312
        out.write(data.getBytes("UTF-8"));
	}
	
	private void test2(HttpServletResponse response) throws IOException,
	UnsupportedEncodingException {
	String data="中国";
	
	OutputStream out =response.getOutputStream(); 
	//用html技术中meta标签模拟了一个http响应头，来控制浏览器的行为
	out.write("<meta http-equiv='content-type'  content='text/html;charset=UTF-8'>".getBytes());
	out.write(data.getBytes("UTF-8"));
	
	out.write((1+"").getBytes());//这样写1才会出来
}




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


		doGet(request,response);
	}
