将嵌套的json数组转换为java数组

import com.fasterxml.jackson.databind.ObjectMapper;

public class JsonArrayConverter {
    public static void main(String[] args) {
        // 假设有一个嵌套的JSON数组的字符串
        String json = "[{\"name\":\"John\",\"age\":30},{\"name\":\"Jane\",\"age\":25}]";

        try {
            // 使用Jackson库解析JSON字符串为Java对象
            ObjectMapper objectMapper = new ObjectMapper();
            Object[] jsonArray = objectMapper.readValue(json, Object[].class);

            // 创建Java数组
            Person[] persons = new Person[jsonArray.length];

            // 遍历嵌套的JSON数组
            for (int i = 0; i < jsonArray.length; i++) {
                // 将每个元素转换为Person对象
                Person person = objectMapper.convertValue(jsonArray[i], Person.class);
                persons[i] = person;
            }

            // 打印转换后的Java数组
            for (Person person : persons) {
                System.out.println(person.getName() + " - " + person.getAge());
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    // 定义Person类，用于存储嵌套的JSON数组中的元素
    static class Person {
        private String name;
        private int age;

        // 省略构造函数、getter和setter方法

        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;
        }
    }
