How to map different name to json property based on rest method per @JsonView in spring boot?

I have 2 set of rest APIs implemented using Spring boot using same Java POJO class. I have to return different fields and with different name for few fields, based on API. Presently I am using @JsonView for one set of API. But I also need to give different name for that @JsonView. Ex: Field 'host' needs to be named as 'ip' for a @JsonView, where as 'host' for other API. I am not sure how to map different property names as per @JsonView.

I checked some results like using MixIns. But not sure how to do in Spring Boot Rest APIs, especially at method level.

public class Con {

@JsonView(View.ConInfo.class)
private String host;

private String name;

}

Controller Method:

@JsonView(View.ConInfo.class)
@GetMapping
public Con getConInfo()  {}

@GetMapping("/raw")
public Con getCon()  {}

Expected: {"ip":"10xxx"} for getConInfo API

{"host":"10xxx", "name":"con1"} for getCon API.

Actual: Getting {"host":"10xxx"} for getConInfo API

Surely there's a way to achieve what you want (see details below). But I encourage you to avoid it.

As you have different payloads, you should have different classes for representing each payload.

If you still want to follow your original path, you could define two views:

public interface Views {

    interface Summary { }

    interface Details { }
}

And then annotate your payload as follows:

@Data
public class Payload {

    @JsonIgnore
    private String host;

    @JsonView(Views.Details.class)
    private String name;

    @JsonView(Views.Summary.class)
    public String getIp() {
        return host;
    }

    @JsonView(Views.Details.class)
    public String getHost() {
        return host;
    }
}

Now consider the following method, annotated with @JsonView(Views.Summary.class)

@JsonView(Views.Summary.class)
@GetMapping(path = "/summary", produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Payload> getSummary() {

    Payload payload = new Payload();
    payload.setHost("0.0.0.0");
    payload.setName("example");

    return ResponseEntity.ok(payload);
}

It will produce:

{
  "ip": "0.0.0.0"
}

Now consider the following methid annotated with @JsonView(Views.Details.class):

@JsonView(Views.Details.class)
@GetMapping(path = "/details", produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Payload> getDetails() {

    Payload payload = new Payload();
    payload.setHost("0.0.0.0");
    payload.setName("example");

    return ResponseEntity.ok(payload);
}

It will produce:

{
  "host": "0.0.0.0",
  "name": "example"
}
