如何使用 Java 中的 flexjson 从 Reader Stream 反序列化 Java 对象?
javajsonobject oriented programmingprogramming
Flexjson 是一个轻量级 库，用于将 Java 对象序列化和反序列化为 JSON 格式。我们可以使用 JSONDeserializer 类的 deserialize() 方法从 Reader 流反序列化 Java 对象，它使用 Reader 类的实例作为 JSON 输入。
语法
public T deserialize(Reader input)
示例
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 +
" ]";
}
}
输出
Student[ firstName = Adithya, lastName = Sai, age = 25, address = Hyderabad ]
