Class我的代码正在到达@Autowired
private ApplicationContext applicationContext;
private JpaTransactionManager userTransactionManager;
private EntityTransaction userTx;
userTransactionManager = (JpaTransactionManager) applicationContext.getBean("provTransactionManager");
userTx = provTransactionManager.getEntityManagerFactory().createEntityManager().getTransaction();
userTx.begin();
boolean isUpdateSuccess = updateViaUserRepository(...);
if(!isUpdateSuccess) {
userTx.rollback();
} else {
userTx.commit();
}
，但是实际的数据库没有回滚。我的userTx.rollback();或persisence配置中是否有任何错误。
编辑：我所有的表的引擎都为applicationContext
答案 0 :(得分：0)
首先要寻找的是：您使用的表类型是什么？
例如，对于MySQL， MyISAM表不支持事务，这意味着您必须使用其他表类型（例如InnoDB）。
