ajax向後臺傳中文亂碼問題

1.把傳的值保存在encodeURI中，記得是雙encodeURI

url:'json/selectUser.action?param='+encodeURI(encodeURI("中文")),

2.在action中解碼

HttpServletRequest request = ServletActionContext.getRequest();
		
		String param = request.getParameter("param");
	    
		param = URLDecoder.decode(param,"UTF-8");

3.輸出param

System.out.println(param);
