我使用jQuery DataTables并收到此警告消息:
DataTables警告:table = userTable - 无效的JSON响应
servlet从MySQL中获取用户,我希望在jQuery Datatable中显示,但是Ajax无法解析JSON或者在servlet中生成错误的JSON？

List<UserDTO> users = this.service.getAllUser();
Gson gson = new Gson();
request.setAttribute("users", gson.toJson(users));
request.getRequestDispatcher("listAllUser.jsp").forward(request, response);
JSP:
