Hi all, suppose I have a json like this , when I am send request to the server, where I am using RestTemplate generate to do this. When I send success request I am getting sucess response like this.

{
    "code": 0,
    "message": "Successfully processed",
 "result": {
        "ContractRs": {
            "Contract": {
                "OrderDprt": "",
                "ClientType": "",
                "ClientCategory": "",

 }
}

but When I send failed request, I am getting response like this:

{
"code": -2000,
"message": "Policy Error"
}

What annotation do I am using to do this soliton in spring boot project using Jackson library?

What I have tried:

I think @JsonIgnoreProperties to solve this problem, but I do not know how to do this?
