How to get response as JSON with ResponseEntity in Java?

I am building an API and do a POST-request with the following method:

public ResponseEntity<ProjectRequest> createProject(ProjectRequest project) {
        ProjectResponse projectResponse = new ProjectResponse();
        PersonMember personMember = new PersonMember();

        String personResponse = restTemplate.postForObject(PERSON_URL, project.getPersonMember(), String.class);

        System.out.println(personResponse);
        return new ResponseEntity<ProjectRequest>(HttpStatus.CREATED);
    }

However, it is inconvenient to work with personResponse as a String, because I can not easily extract values from the response Such as personID, firstName and etc.

What is a good way to work with the key/value pairs when using responseEntity?

Whenever you pass a POJO to the ResponseEntity, Spring converts it to a Json. So try to create a POJO for your PersonResponse(If it isn't a POJO already) and pass the object directly to ResponseEntity. It should look like this:

class PersonResponse{
long id;
String name;
String description;

//Getters and setters for the fields.
}

This might help :

Spring: return @ResponseBody "ResponseEntity<List<JSONObject>>"

Using anotations ( @ResponseBody ResponseEntity ) and using a JSON as an object for your response might answer your question.

You should leave this work to Spring.

Create some kind of PersonDto

public class PersonDto {
    private String firstName;
    private String lastName;
    //etc.

    //getters and setters

}

And then map the response to this PersonDto as:

ResponseEntity<PresonDto> response = restTemplate
                    .postForEntity(PERSON_URL, project.getPersonMember(), PersonDto.class);
PersonDto presonDto = response.getBody();
