Bagaimana untuk menyahsiri objek Java dari aliran Pembaca di Java menggunakan flexjson?

Flexjson ialah ringan perpustakaan untuk mensiri format Java dan mensiri objek kepada format JSON. Kita boleh menyahsiri objek Java daripada strim Pembaca menggunakan kaedah deserialize() bagi kelas JSONDeserializer , yang menggunakan instance bagi Reader #🎜 # kelas Sebagai input JSON.

Tatabahasa

public T deserialize(Reader input)

Contoh

import java.io.*;
import flexjson.JSONDeserializer;
public class JSONDeserializeReaderTest {
   public static void main(String[] args) {
      JSONDeserializer<Student> deserializer = new JSONDeserializer<Student>();
      String jsonStr =
                       "{" +
                        "\"firstName\": \"Adithya\"," +
                        "\"lastName\": \"Sai\"," +
                        "\"age\": 25," +
                        "\"address\": \"Hyderabad\"" +
                        "\"class\": \"Student\"" +
                       "}";
      Student student = deserializer.deserialize(new StringReader(jsonStr));
      System.out.println(student);
   }
}
// Student class
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 void setFirstName(String firstName) {
      this.firstName = firstName;
   }
   public String getLastName() {
      return lastName;
   }
   public void setLastName(String lastName) {
      this.lastName = lastName;
   }
   public int getAge() {
      return age;
   }
   public void setAge(int age) {
      this.age = age;
   }
   public String getAddress() {
      return address;
   }
   public void setAddress(String address) {
      this.address = address;
   }
   public String toString() {
      return "Student[ " +
      "firstName = " + firstName +
      ", lastName = " + lastName +
      ", age = " + age +
      ", address = " + address +
      " ]";
   }
}

Output

Student[ firstName = Adithya, lastName = Sai, age = 25, address = Hyderabad ]
