Java com.fasterxml.jackson.core.JsonParseException:意外字符（'；='；（代码61））

我正在使用ParamQuery供应商的网格组件。 我的spring控制器使用Jackson库将JSON数据转换为DepartmentHeadDTO（Pojo类）

当我使用AJAX发出这样的请求时，它会被执行

请求：

 dataModel: {
                location: "remote",
                sorting: "local",
                dataType: "JSON",
                url: "/ExpenseManagement/departmentHead", 
                method: "POST",
                beforeSend: function(xhr) {                 
                       xhr.setRequestHeader("Accept", "application/json");
                       xhr.setRequestHeader("Content-Type", "application/json");
                   },
                error: function () {
                    //$gridMain.pqGrid( 'rowInvalidate', { rowData: rowData });
                },

                postData: JSON.stringify(jsonToBeSend),
                //url = "/pro/orderdetails.php?orderId=" + orderID //for PHP
            },
            colModel: [
                { title: "BranchName", width: 80, dataIndx: "departmentId" }

            ],

JSON数据：

var jsonToBeSend=new Object();
      jsonToBeSend["branchId"] = "1";

弹簧控制器：

    @RequestMapping(value="/departmentHead",method=RequestMethod.POST)
public @ResponseBody List<DepartmentHeadDTO> getDepartmentHead(@RequestBody DepartmentHeadDTO receivedDepartmentHeadDTO){
    List<DepartmentHeadDTO> departmentHeadDTOList = null;
    LoginUserDetails user = (LoginUserDetails)SecurityContextHolder.getContext().getAuthentication().getPrincipal();
    if(Validation.validateForNullObject(user.getLoginDTO().getEmployeeDTO())){

         departmentHeadDTOList = deptHeadSerrvice.findDepartmentHeadUnderCompany(receivedDepartmentHeadDTO);
    }

    return departmentHeadDTOList;
}

错误：

请帮我摆脱它。谢谢。

如果您提供一个发布到服务器的json示例，会有所帮助。www.paramquery.com/demohey，您是如何解决这个问题的？在android中解析Response时遇到几乎相同的问题如果您包含一个发布到服务器上的json示例，将提供帮助。www.paramquery.com/demohey，您是如何解决此问题的？在android中解析响应时遇到几乎相同的问题
