How to control serialization through @JSON annotation using flexjson in Java?
The @JSON annotation is used by JSONSerializer class to exclude or include a field during the serialization process. We can use the serialize() method of JSONSerializer class to perform a shallow serialization of the target instance.
Syntax
@Retention(value=RUNTIME)
@Target(value={FIELD,TYPE,METHOD})
public @interface JSONExample
import flexjson.JSONSerializer;
import flexjson.JSON;
public class JSONAnnotationTest {
public static void main(String[] args) {
JSONSerializer serializer = new JSONSerializer().prettyPrint(true);
Employee emp = new Employee("Raja", "Ramesh", 30, "Hyderabad");
String jsonStr = serializer.serialize(emp);
System.out.println(jsonStr);
}
}
// Employee class
class Employee {
private String firstName, lastName, address;
private int age;
public Employee(String firstName, String lastName, int age, String address) {
super();
this.firstName = firstName;
this.lastName = lastName;
this.age = age;
this.address = address;
}
public String getFirstName() {
return firstName;
}
@JSON(include=false)
public String getLastName() {
return lastName;
}
public int getAge() {
return age;
}
@JSON(include=false)
public String getAddress() {
return address;
}
}Output
{
"age": 30,
"class": "Employee",
"firstName": "Raja"
}
