如何使用jackson反序列化包含对象数组的JSON表示？

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.12.5</version>
</dependency>

{
  "name": "John",
  "age": 30,
  "hobbies": ["reading", "swimming", "coding"]
}

public class Person {
    private String name;
    private int age;
    private String[] hobbies;

    // 省略构造函数、getter和setter方法
}

ObjectMapper objectMapper = new ObjectMapper();
Person person = objectMapper.readValue(jsonString, Person.class);

{
  "name": "John",
  "age": 30,
  "friends": [
    {"name": "Alice", "age": 28},
    {"name": "Bob", "age": 32}
  ]
}

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

    // 省略构造函数、getter和setter方法
}

public class Person {
    private String name;
    private int age;
    private List<Friend> friends; // 或 Friend[] friends;

    // 省略构造函数、getter和setter方法
}
