我使用jQuery DataTables并收到此警告消息：
[DataTables警告：table = userTable-无效的JSON响应
一个servlet从MySQL获取用户，我想在jQuery数据表中显示该用户，但是Ajax无法解析JSON或JSON在servlet中生成错误？
Servlet：
List<UserDTO> users = this.service.getAllUser();
Gson gson = new Gson();
request.setAttribute("users", gson.toJson(users));
request.getRequestDispatcher("listAllUser.jsp").forward(request, response);
JSP：
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

$(document).ready(function() {
$('#userTable').dataTable({

<body>
<table id="userTable" class="display">

由Servlet生成的JSON：
[
{
"id": 1,
"userName": "userName1",
"firstName": "firstName1",
"lastName": "lastName1",
"email": "[email protected]",
"phone": "36202080085",
"location": "location1",
"password": "password1",
"gender": "m",
"birthday": "1-02-2015"
}
]
"serverSide": true启用了服务器端处理模式，但是您的数据被格式化为客户端处理模式。删除"serverSide": true以使用客户端处理模式。您需要使用下面显示的dataSrc: ""灰以匹配JSON数据格式，有关更多信息，请参见dataSrc。
dataSrc"ajax" : {
"url" : "ListAllUserServlet",
"type" : "POST",
"dataSrc": ""
},
