JsonIgnoreProperties not working

Question

I have the following simple class:

import org.codehaus.jackson.annotate.JsonIgnoreProperties;
@JsonIgnoreProperties({ \"thirdField\" })
public class Message          


        

Answer 1

You've mixed different versions of Jackson. Notice that you import JsonIgnoreProperties from org.codehaus.jackson.annotate (version 1.x) while you're using ObjectMapper from com.fasterxml.jackson.databind (version 2.x).

Answer 2

I found a Solution to this. Try to add

@JsonSerialize(include= JsonSerialize.Inclusion.NON_EMPTY)

About your class

@JsonSerialize(include= JsonSerialize.Inclusion.NON_EMPTY)
class ResponseModel {
 //your properties here
 @JsonIgnoreProperties("messageList","contactList","sender")
    var contactList= ArrayList<ContactModel>()
}

That will solve your issue buddy.

Answer 3

It didn't work for me any of the above answers, i found a workaround that I have reinitialized the object and values (copied the object).

Answer 4

Try using the last Jackson version (2.4):

import com.fasterxml.jackson.annotation.JsonIgnoreProperties
@JsonIgnoreProperties({"id"})

Here you can find an example where it's implement using version 2.4: http://www.ibm.com/developerworks/java/library/j-hangman-app/index.html
