I have a source A, a wrapper API B and a destination C.
I have to call wrapper API B from destination C. I have no access to source A.

source A produces following json output:

{
"id" : 1,
"created_on" : "27July"
}

In wrapper API B, I am consuming the above JSON output using following POJO:

class B
{
Long id;
String created_on;
}

Wrapper API is able to get the value of created_on from source A. When I call A from B, I get this ouptut:

{
"id" : 1,
"created_on" : "27July"
}

But in destination C, i have the following POJO:

class C
{ 
Long id
String createdOn 
}

When I call Wrapper API B from C, i am not able to get the field ‘createdOn’.
When I call B from C, i get only this:

{
          "id" : 1
}

The mapping between created_on and createdOn is not happening.
Basically, i want to return ‘createdOn’ from Wrapper API B instead of ‘created_on’.
Currently, wrapper B is sending ‘created_on’ , but i want it to return ‘createdOn’.
How do I do it? I have tried @JSONProperty but it is not working

>Solution :

public class C { 
    Long id
    @JsonProperty("created_on")
    String createdOn 
}

It’s should works.
