如何使用 Java 中的 flexjson 序列化对象数组?
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。我们还可以使用 JSONSerializer 类的 serialize() 方法序列化对象数组，这将对目标实例执行浅层序列化。
语法
public String serialize(Object target)
在下面的程序中，我们需要序列化对象数组。
示例
import flexjson.JSONSerializer;
public class JsonSerializeArrayTest {
public static void main(String[] args) {
JSONSerializer serializer = new JSONSerializer().prettyPrint(true);
Student stud1 = new Student("Adithya", "Sai", 28, "Hyderabad");
Student stud2 = new Student("Jai", "Dev", 30, "Chennai");
Student stud3 = new Student("Ravi", "Chandra", 35, "Pune");
Student[] students = {stud1, stud2, stud3};
String jsonStr = serializer.serialize(students);
System.out.println(jsonStr);
}
}
// Student classclass 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 +
" ]";
}
}
输出
[
{
"address": "Hyderabad",
"age": 28,
"class": "Student",
"firstName": "Adithya",
"lastName": "Sai"
},
{
"address": "Chennai",
"age": 30,
"class": "Student",
"firstName": "Jai",
"lastName": "Dev"
},
{
"address": "Pune",
"age": 35,
"class": "Student",
"firstName": "Ravi",
"lastName": "Chandra"
}
]
