没有从spring控制器和jquery .post（）方法中获取正确的json

I am new at spring framework. I am sending request through the $.post() method from view page and my controller receives data from my DAO class. But I am not getting the full data. I am posting my source code

我是Spring框架的新手。我通过视图页面中的$ .post（）方法发送请求，我的控制器从我的DAO类接收数据。但我没有得到完整的数据。我发布了我的源代码

$.post("/diusoftware/showAppraisalFormatWithDetails"+"/41",{id:41},function(data){
            alert(JSON.stringify(data));
        }, "json");

I found output when System.out from controller

我从控制器发现了System.out的输出

AppraisalFormatMaster [id=41, formatName=Template for IT Department, formVersionNo=1, markVersionNo=1, createdBy=0, appraisalFormatDetailList=[AppraisalFormatDetail [id=19, appraisalHeads=1, appraisor=1,2], AppraisalFormatDetail [id=20, appraisalHeads=2, appraisor=1,2], AppraisalFormatDetail [id=21, appraisalHeads=3, appraisor=1,2], AppraisalFormatDetail [id=22, appraisalHeads=4, appraisor=3,4]]]

But I found the output in $.post() method

但我在$ .post（）方法中找到了输出

[{"id":41,"formatName":"Template for IT Department","formVersionNo":"1","markVersionNo":1,"createdBy":0}]

You don't have any of the detail records on the Javascript side because you have @JsonIgnore on the collection inside your AppraisalFormatMaster class.

您在Javascript端没有任何详细记录，因为您在AppraisalFormatMaster类的集合中有@JsonIgnore。
