### Spring 管理事务的方式有几种？

- **编程式事务**：在代码中硬编码(不推荐使用) : 通过 `TransactionTemplate`或者 `TransactionManager` 手动管理事务，实际应用中很少使用，但是对于你理解 Spring 事务管理原理有帮助。
- **声明式事务**：在 XML 配置文件中配置或者直接基于注解（推荐使用） : 实际是通过 AOP 实现（基于`@Transactional` 的全注解方式使用最多）
- **编程式事务**：在代码中硬编码(在分布式系统中推荐使用) : 通过 `TransactionTemplate`或者 `TransactionManager` 手动管理事务，事务范围过大会出现事务未提交导致超时，因此事务要比锁的粒度更小。
- **声明式事务**：在 XML 配置文件中配置或者直接基于注解（单体应用或者简单业务系统推荐使用） : 实际是通过 AOP 实现（基于`@Transactional` 的全注解方式使用最多）
