@JsonProperty(access = Access.READ_ONLY) - unexpected behaviour

Hey,

I was hoping to make use of @JsonProperty(access = Access.READ_ONLY), but failed.

Assume this class:

public class TestPojo
{
    private String firstName;

    private String lastName;

    @JsonProperty(access = Access.READ_ONLY)
    public String getFullName()
    {
        return firstName + " " + lastName;
    }

    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;
    }
}

I couldn’t find a way to stop the deserializer from attempting to deserialize the field “fullName”. The only thing that helps is to create a setter and annotate it with @JsonIgnore. However, that setter does not make sense and I don’t want to have it. Is this a bug in behaviour or am I missing something? Thanks

Hi,

is there some easy workaround, until this is fixed? I mean instead of implementing a noop setter method?

The annotation @JsonIgnoreProperties sounds like it could help here. But it also has no effect, if I add it to a getter, regardless which values I choose for allowGetters or allowSetters.

Update: It seems that I found a solution by adding

@JsonIgnoreProperties(value="some_field", allowGetters = true, allowSetters = false)

to the class. So this could be a solution, if we don’t need the @JsonIgnoreProperties annotation on class level for other purposes.

Also: my earlier explanation was exactly backwards. Javadocs state it correctly (if not well): READ_ONLY refers to POJO being handled in read-only way, and WRITE_ONLY opposite. So Java-centric, not JSON-centric.

I really should have named values differently (GETTER_ONLY, SETTER_ONLY, perhaps).
