ext乱码解决

1.把相关的java ,jsp,js 文件编码方式都改成utf-8

2.

response.setContentType("text/json;charset=utf-8");
   response.setHeader("text/json", message);
     response.setHeader("Cache-Control", "no-cache");

3.使用如下代码对你的request,response进行测试，看看到底是什么编码

System.out.println(response.getCharacterEncoding()+"###");

System.out.println(request.getCharacterEncoding()+"####");

如果输出都为utf-8就解决了。

一个完整的处理方法如下：

private void print(JSONObject message) {
   HttpServletResponse response = ServletActionContext.getResponse();
   HttpServletRequest request = ServletActionContext.getRequest();
response.setHeader("X-JSON", message.toString());
   response.setCharacterEncoding("UTF-8");
   response.setHeader("Cache-Control", "no-cache");
   PrintWriter print = null;
   try {
    print = response.getWriter();
   } catch (IOException e) {
    e.printStackTrace();
   }
   print.print(message.toString());
   print.flush();
}
