{
  "in": [
    {
      "name": "John",
      "age": 25
    },
    {
      "name": "Jane",
      "age": 30
    }
  ]
}

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

    // 省略构造方法、getter和setter
}

import com.fasterxml.jackson.databind.ObjectMapper;

public class JsonToPojoConverter {
    public static Person[] convertJsonToPojoArray(String json) throws IOException {
        ObjectMapper objectMapper = new ObjectMapper();
        JsonNode rootNode = objectMapper.readTree(json);
        JsonNode inNode = rootNode.get("in");
        return objectMapper.convertValue(inNode, Person[].class);
    }
}

String json = "{\"in\":[{\"name\":\"John\",\"age\":25},{\"name\":\"Jane\",\"age\":30}]}";
Person[] persons = JsonToPojoConverter.convertJsonToPojoArray(json);
