ObjectMapper not considering annotations

I have the below piece of code which would convert an annotated Java object into Json String.

try {
String jsonString = mapper.writeValueAsString(obj);
LOGGER.debug("logAsJson", jsonString);
} catch (Exception e) {
LOGGER.warn("logAsJson", "Exception in logging only. Nothing critical! ", e);
}


And my class would look something like this

public class Car {

@JsonProperty("capabilities")
private List<Capability> capability = new ArrayList<Capability>();

@JsonProperty("periodicity")
@NotNull
private Periodicity periodicity;

@JsonProperty("car_driver")
private List<carDriver> carDriver = new ArrayList<carDriver>();


}

Problem is that while creating the json string from the object, object mapper is not considering the annotations for field names.

Thanks in advance.

The json annotation and the object mapper may not be from the same library. Make sure you have imported the same library in both the files.

Example,

import com.fasterxml.jackson.annotation.JsonProperty;

import com.fasterxml.jackson.annotation.JsonProperty;

and

import com.fasterxml.jackson.databind.ObjectMapper;
