servlet POST 接受数据中文乱码

[ccnce]

网上很多方案是：
response.setCharacterEncoding("utf-8");
response.setContentType("text/html;charset=utf-8");

但是浏览出来还是乱码


POST代码

public void doPost(HttpServletRequest request, HttpServletResponse response)
      throws ServletException, IOException
	{
		  response.setCharacterEncoding("utf-8"); 
		  response.setContentType("text/html;charset=utf-8");
		  String names=request.getParameter("dddd");
		  //String str = new String(names.getBytes("ISO-8859-1"),"utf-8");
		  PrintWriter out = response.getWriter(); 
		  out.println("<h1>" + names + "</h1>");
	}

我测试过，只能用String str = new String(names.getBytes("ISO-8859-1"),"utf-8");这样才能正常。为什么？
response.setCharacterEncoding("utf-8");
response.setContentType("text/html;charset=utf-8");
为什么无效？
提交页面也是设置了utf-8的,

你提交是post乱码吧？用request.setCharacterEncoding("UTF-8");

这样就OK了

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

解决了
