您可以通过注册自定义反序列化程序进行转换，如下所示：

public class PersonDeserializer extends JsonDeserializer<Person> {

    @Override
    public Person deserialize(JsonParser jp, DeserializationContext ctxt) throws IOException {
        ObjectCodec oc = jp.getCodec();
        JsonNode node = oc.readTree(jp);

        final Integer age = node.get("age").asInt();
        final String name = node.get("name").asText();
        final String hobbyListAsString = node.get("hobby_list").asText();

        ObjectMapper mapper = new ObjectMapper();
        // convert JSON array to List of objects
        List<Hobby> hobbyList = Arrays.asList(mapper.readValue(hobbyListAsString, Hobby[].class));

        Person person = new Person();
        person.setName(name);
        person.setAge(age);
        person.setHobbyList(hobbyList);

        return person;
    }
}

在根目录下的pojo中使用注解 @JsonDeserialize(using = PersonDeserializer.class) 以便可以注册上述反序列化程序。附上以下参考资料：

@JsonDeserialize(using = PersonDeserializer.class)
@Data
public class Person {
    @JsonProperty("name")
    private String name;

    @JsonProperty("age")
    private Integer age;

    @JsonProperty("hobby_list")
    private List<Hobby> hobbyList;
}

然后我能够将上面的列表字符串反序列化到对象

ObjectMapper mapper = new ObjectMapper();
Person person = mapper.readValue(content, Person.class);
System.out.println(person.getHobbyList());
