I get this Json response:
{

"student": {
   "firstName": "john",
   "lastName": "doe"
   "isActive": false
}

Now, I don’t want to include isActive from the response. I have this class ClassDto:

@JsonInclude(JsonInclude.Include.NON_NULL)
@JsonIgnoreProperties(value = { "student.isActive" })
public class ClassDto implements Serializable
{
     private StudentDto student;

     public StudentDto getStudent()
     {
         return student;
     }

     public void setStudent(StudentDto student)
     {
         this.student = student;
     }
}

Here is also my StudentDto class:

@JsonInclude(Include.NON_NULL)
public class StudentDto implements Serializable
{
    @JsonProperty("firstName")
    private String firstName;

    @JsonProperty("lastName")
    private String lastName;

    @JsonProperty("isActive")
    private boolean isActive;

    public String getFirstName()
    {
        return firstName;
    }

    public void setFirstName(String firstName)
    {
        this.firstName = firstName;
    }
    
    public String getLastName()
    {
        return lastName;
    }

    public void setLastName(String lastName)
    {
        this.lastName = lastName;
    }

    public boolean isActive()
    {
        return isActive;
    }

    public void setIsActive(boolean isActive)
    {
        this.isActive = isActive;
    }
    
}

I created a mapper class ClassMapper:

public class ClassMapper
{
    private final StudentVo studentVo

    public ClassMapper(StudentVo studentVo)
    {
        this.studentVo = studentVo;
    }

    public ClassDto mapToResource() throws VerifyException
    {
        final ClassDto classDto = new ClassDto();
        StudentDto studentDto = new StudentDto();
        
        extractStudent(studentDto, studentVo);
        classDto.setStudent(studentDto);

        return classDto;
    }

    private void extractStudent(StudentDto studentDto,
        StudentVo studentVo)
    {
        studentDto.setFirstName(studentVo.getFirstName());
        studentDto.setLastName(studentVo.getLastName());
    }
    
}

I am currently reusing an existing class StudentDto in my ClassDto since it has the fields that I need except that I don’t want ‘isActive’ field to show in the Json response. As you can see, I have added @JsonIgnoreProperties(value = { "student.isActive" }) in my ClassDto and unfortunately, this is not working. I tested adding the @JsonIgnore in StudentDto.isActive field and it works. However, since this class is being used by other classes, I don’t want to change the codes in this class. What is wrong with my code? How can I exclude the isActive field from my Json response?
