What is the use of @JsonRawValue annotation using Jackson API in Java?
The @JsonRawValue annotation can be used for both methods and fields to serialize field or property as declared. For instance, if we have a String field in our Java class, the JSON value is enclosed within quotes (“ "). But when we annotate the field with @JsonRawValue annotation, Jackson library omits the quotes.
Syntax
@Target(value={ANNOTATION_TYPE,METHOD,FIELD})
@Retention(value=RUNTIME)
public @interface JsonRawValueIn the below example, the empAddress field is a JSON string. This JSON string serialized as a part of the final JSON string of Employee object.
Example
import com.fasterxml.jackson.annotation.JsonRawValue;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.core.JsonProcessingException;
public class JsonRawValueAnnotationTest {
public static void main(String args[]) throws JsonProcessingException {
ObjectMapper mapper = new ObjectMapper();
String jsonString = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(new Employee());
System.out.println(jsonString);
}
}
// Employee class
class Employee {
public int empId = 115;
public String empName = "Sai Chaitanya";
@JsonRawValue
public String empAddress = "{\"doorNumber\": 1118, \"street\": \"IDPL Colony\", " + "\"city\": \"Hyderabad\"}";
}Output
{
"empId" : 115,
"empName" : "Sai Chaitanya",
"empAddress" : {"doorNumber": 1118, "street": "IDPL Colony", "city": "Hyderabad"}
}
