transactionManager
A transaction manager is a software component that is responsible for ensuring that database transactions are executed reliably and consistently. It acts as a coordinator between the application and the database, providing a unified interface for managing transactions. The transaction manager is responsible for ensuring that all transactions are atomic, consistent, isolated, and durable. It also provides features such as transaction logging, recovery, and concurrency control to ensure that data is not lost or corrupted during the transaction process. Transaction managers are commonly used in enterprise applications to ensure data consistency across multiple systems and databases.

TransactionManager是Java事务API的核心接口,它定义了事务管理器的基本行为和操作。TransactionManager是JTA API的一部分,用于管理分布式事务。它允许应用程序将多个事务性资源组合在一起成为一个全局事务,并提供了将所有事务性资源提交或回滚的机制。
以下是TransactionManager的一些基本操作方法[^1][^2]:
```java
/**
* 开始事务
* @throws SystemException
*/
void begin() throws SystemException;
/**
* 提交事务
* @throws HeuristicMixedException
* @throws HeuristicRollbackException
* @throws IllegalStateException
* @throws RollbackException
* @throws SecurityException
* @throws SystemException
*/
void commit() throws HeuristicMixedException, HeuristicRollbackException, IllegalStateException, RollbackException, SecurityException, SystemException;
/**
* 回滚事务
* @throws IllegalStateException
* @throws SecurityException
* @throws SystemException
*/
void rollback() throws IllegalStateException, SecurityException, SystemException;
/**
* 获取当前事务
* @return Transaction
* @throws SystemException
*/
Transaction getTransaction() throws SystemException;
```
以上是TransactionManager的基本操作方法,通过这些方法,我们可以在多个资源之间创建分布式事务,并对其进行管理和控制。
