要通过Json在java中列出的Json数组。

import com.fasterxml.jackson.databind.ObjectMapper;

public class JsonArrayExample {
    public static void main(String[] args) {
        // JSON数组字符串
        String jsonArrayStr = "[{\"name\":\"Alice\",\"age\":20},{\"name\":\"Bob\",\"age\":25}]";
        
        // 创建ObjectMapper对象
        ObjectMapper objectMapper = new ObjectMapper();
        
        try {
            // 将JSON数组字符串解析为Java对象数组
            Person[] persons = objectMapper.readValue(jsonArrayStr, Person[].class);
            
            // 遍历打印每个对象的属性
            for (Person person : persons) {
                System.out.println("Name: " + person.getName());
                System.out.println("Age: " + person.getAge());
                System.out.println("---------------");
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

class Person {
    private String name;
    private int age;
    
    // 省略构造方法和getter/setter方法
}

import javax.json.Json;
