//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);
	}
