Json – Jackson JSON Ignore Properties Dynamically

jacksonjson

I have the following classes –

Employee

public class Employee {

    private String firstName ;
    private String lastName ;
    private String emailAddress ; 
    private String ssn ;
}

Payroll

public class Payroll {

    // different payroll related fields

    private Employee emp ;

}

HR

public class HR {

    // different HR related fields

    private Employee emp ;

}

Now when I serialize my Payroll class, I don't want to serialize my ssn field from Employee class.

Where as when I serialize my HR class, I don't want to serialize my emailAddress field from Employee class.

How I can dynamically exclude fields from serializing by using Jackson JSON API?

This seems like a prime candidate for applying JacksonJsonViews.

public class Employee {

    private String firstName;
    private String lastName;
    @JsonView(Views.Payroll.class) private String emailAddress; 
    @JsonView(Views.HR.class) private String ssn;
}

public class Payroll {
    // snip

    @JsonView(Views.Payroll.class)
    private Employee emp;
}

public class HR {
    // snip

    @JsonView(Views.HR.class)
    private Employee emp;
}
