用spring boot在mongodb中“更新复杂文档”的正确方法是什么？

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>

@Document(collection = "your_collection_name")
public class YourEntity {
    @Id
    private String id;
    private String field1;
    private String field2;
    // 其他字段...
    
    // 省略构造方法、getter和setter
}

@Repository
public interface YourRepository extends MongoRepository<YourEntity, String> {
    @Query("{'id': ?0}")
    YourEntity updateComplexDocument(String id, Update update);
}

@Autowired
private YourRepository yourRepository;

public void updateDocument(String id, String newFieldValue) {
    Update update = new Update();
    update.set("field1", newFieldValue);
    // 设置其他需要更新的字段...
    
    YourEntity updatedEntity = yourRepository.updateComplexDocument(id, update);
    // 处理更新后的实体对象...
}
