@JsonRootName allows to have a root node specified over the JSON. We need to enable wrap root value as well.
Example @JsonRootName
import java.io.IOException; import com.fasterxml.jackson.annotation.JsonRootName; import com.fasterxml.jackson.databind.ObjectMapper; import com.fasterxml.jackson.databind.SerializationFeature; public class JacksonTester { public static void main(String args[]){ ObjectMapper mapper = new ObjectMapper(); try { Student student = new Student("Mark", 1); mapper.enable(SerializationFeature.WRAP_ROOT_VALUE); String jsonString = mapper .writerWithDefaultPrettyPrinter() .writeValueAsString(student); System.out.println(jsonString); } catch (IOException e) { e.printStackTrace(); } } } @JsonRootName(value = "student") class Student { private String name; private int rollNo; public Student(String name, int rollNo){ this.name = name; this.rollNo = rollNo; } public String getName(){ return name; } public int getRollNo(){ return rollNo; } }
Output
{ "student" : { "name" : "Mark", "rollNo" : 1 } }
