@JsonRawValue allows to serialize a text without escaping or without any decoration.
Example without @JsonRawValue
import java.io.IOException; import com.fasterxml.jackson.databind.ObjectMapper; public class JacksonTester { public static void main(String args[]){ ObjectMapper mapper = new ObjectMapper(); try { Student student = new Student("Mark", 1, "{"attr":false}"); String jsonString = mapper .writerWithDefaultPrettyPrinter() .writeValueAsString(student); System.out.println(jsonString); } catch (IOException e) { e.printStackTrace(); } } } class Student { private String name; private int rollNo; private String json; public Student(String name, int rollNo, String json){ this.name = name; this.rollNo = rollNo; this.json = json; } public String getName(){ return name; } public int getRollNo(){ return rollNo; } public String getJson(){ return json; } }
Output
{ "name" : "Mark", "rollNo" : 1, "json" : {"attr":false} }
Example with @JsonRawValue
import java.io.IOException; import com.fasterxml.jackson.databind.ObjectMapper; import com.fasterxml.jackson.annotation.JsonRawValue; public class JacksonTester { public static void main(String args[]){ ObjectMapper mapper = new ObjectMapper(); try { Student student = new Student("Mark", 1, "{"attr":false}"); String jsonString = mapper .writerWithDefaultPrettyPrinter() .writeValueAsString(student); System.out.println(jsonString); } catch (IOException e) { e.printStackTrace(); } } } class Student { private String name; private int rollNo; @JsonRawValue private String json; public Student(String name, int rollNo, String json) { this.name = name; this.rollNo = rollNo; this.json = json; } public String getName(){ return name; } public int getRollNo(){ return rollNo; } public String getJson(){ return json; } }
Output
{ "name" : "Mark", "rollNo" : 1, "json" : {"attr":false} }
