For example, my Spring boot Java API was returning: 

{
    "contact": "John Smith",
    "badgeNumber": "12345",
    "inProcess": true
}

Then I added SpringFox dependencies for Swagger and now all my API is returning: 

{
    "contact": "John Smith",
    "badgeNumber": "12345",
    "supervisor": null,
    "inProcess": true,
    "employeeReference": null,
    "vacationDates": null
}

Everything in swagger is working smoothly, but I don't want these null fields to return. They should be excluded from the response by default. Any ideas?

  • @Asanka I have tried this and it does not work. – doct03 Sep 27 '18 at 18:31
  • @Asanka I have figured it out. That answer was partially correct for my use case. I had to include the @JsonInclude(JsonInclude.Include.NON_NULL) annotation at the class level, not at the ObjectMapper. – doct03 Sep 27 '18 at 18:51
