I have added @JsonInclude(Include.NON_NULL) annotation on Response class.
@JsonInclude(Include.NON_NULL)
public class Response {
@JsonProperty
private String message;
// getter-setters
}
If the value is null the property does not include in JSON
But still I am getting this property as a NULL.
{
"message": null
}
What can be the reason ? Am I missing anything ?

I tried
@JsonSerialize(include = Inclusion.NON_NULL)
intead of
@JsonInclude(Include.NON_NULL)
and it worked as expected.
This is the correct way of using it. This I valid from jdk 8 +.
@JsonInclude(JsonInclude.Include.NON_EMPTY)
more information is available in : json-include-non-empty
This has been deprecated:
@JsonSerialize(include = JsonSerialize.Inclusion.NON_NULL)
Use instead:
@JsonInclude(Include.NON_NULL)
I am using Java Spring & in that, I am implementing like :
Class Level:
import com.fasterxml.jackson.annotation.JsonInclude;
@JsonInclude(JsonInclude.Include.NON_NULL)
public class Student {
String name;
//getter-setter
}
You can also implement it on elements level of class :
Elements Level:
import com.fasterxml.jackson.annotation.JsonInclude;
@JsonInclude(JsonInclude.Include.NON_NULL)
public class Student {
String name;
@JsonInclude(JsonInclude.Include.NON_NULL)
String address;
//getter-setter
}
I encountered the same issue Solved by using
@JsonInclude(value = Include.NON_EMPTY, content = Include.NON_NULL)
