I'm developing a back-end web application using Spring Boot with Java and I have the following problem: A REST service returns me the following JSON:
{
"cap":"98888"
}
This is my JAVA class which models the output based on the content:
@NoArgsConstructor
@Data
public class MyObject {
private String cap;
}
I would like to change the field name for MY service to return the following JSON:
{
"CAP":"98888"
}
In my JAVA code, I make the call via RestTemplate, like this:
return restTemplate.postForObject(uriBuilder.build().toUri(), new HttpEntity<>(request, headers), MyObject.class);
I've tried to use tons of stuff with Jackson, including @JsonProperty, like this:
@NoArgsConstructor
@Data
public class MyObject {
@JsonProperty("CAP")
private String cap;
}
But the result is this:
{
"CAP":null
}
As if it no longer matches the original name of the property. In practice I can only get an output with correct value but original field name (WHICH I DON'T WANT) or an output with the name of the field I want (i.e. CAP) but with a null value.
Which is the right way to rename properties with Spring annotations?
