Flexjson est une bibliothèque légère pour la sérialisation et la désérialisation des objets Java > et du format JSON. Nous pouvons sérialiser la liste d'objets en utilisant la méthode serialize() de la classe JSONSerializer. Cette méthode peut effectuer une shallowsérialisation sur l'instance cible. Nous devons passer une liste d'objets de type list en paramètre à la méthode serialize().
public String serialize(Object target)
import flexjson.JSONSerializer; import java.util.*; public class JsonSerializeListTest { public static void main(String[] args) { JSONSerializer serializer = new JSONSerializer().prettyPrint(true); // pretty print JSON Student s1 = new Student("Raja", "Ramesh", 28, "Hyderabad"); Student s2 = new Student("Suresh", "Kumar", 30, "Chennai"); Student s3 = new Student("Surya", "Krishna", 35, "Pune"); List<Student> students = Arrays.asList(s1, s2, s3); String jsonStr = serializer.serialize(students); System.out.println(jsonStr); } } // Student class<strong> </strong>class Student { private String firstName; private String lastName; private int age; private String address; public Student() {} public Student(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; } public String getLastName() { return lastName; } public int getAge() { return age; } public String getAddress() { return address; } public String toString() { return "Student[ " + "firstName = " + firstName + ", lastName = " + lastName + ", age = " + age + ", address = " + address + " ]"; } }
[ { "address": "Hyderabad", "age": 28, "class": "Student", "firstName": "Raja", "lastName": "Ramesh" }, { "address": "Chennai", "age": 30, "class": "Student", "firstName": "Suresh", "lastName": "Kumar" }, { "address": "Pune", "age": 35, "class": "Student", "firstName": "Surya", "lastName": "Krishna" } ]
