$.ajax({

url:"url",

data:{Value:value},

dataType:"text",

success:function(data){}

})

 

JsonArray rejs = JsonArray.fromObject();

request.setCharacterEncoding("utf-8"); //这里不设置编码会有乱码

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

response.setHeader("Cache-Control", "no-cache");

PrintWriter out = response.getWriter();

out.print(rejs.toString());

out.close();

 

试验可以成功！！
