Want to hide some fields of an object that are being mapped to JSON by Jackson

Question

I have a User class that I want to map to JSON using Jackson.

public class User {
    private String name;
    private int age;
    prviate int securityCode;         


        

Answer 1

You have two options:

1. Jackson works on setters-getters of fields. So, you can just remove getter of field which you want to omit in JSON. ( If you don't need getter at other place.)

2. Or, you can use the @JsonIgnore annotation of Jackson on getter method of that field and you see there in no such key-value pair in resulted JSON.

   @JsonIgnore
   public int getSecurityCode(){
      return securityCode;
   }
