fastjson 的 JSONArray 与 ArrayList 和 String 的相互转换

public class Person {
    private String name;
    private int age;

    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
}

Person person = new Person();
person.setName("a");
person.setAge(1);

Person person1 = new Person();
person1.setName("b");
person1.setAge(2);

List<Person> personList = new ArrayList<>();
personList.add(person);
personList.add(person1);

JSONArray jsonArray = JSONArray.parseArray(JSON.toJSONString(personList));

String str = jsonArray.toJSONString();

JSONArray jsonArray1 = JSONArray.parseArray(str);

List<Person> list = JSONObject.parseArray(jsonArray1.toJSONString(), Person.class);
