解决No EntityManager with actual transaction available for current thread

问题描述：

在使用JPA执行删除操作时报错：

No EntityManager with actual transaction available for current thread - cannot reliably process 'remove' call; nested exception is javax.persistence.TransactionRequiredException: No EntityManager with actual transaction available for current thread - cannot reliably process 'remove' call

解决方法：

在对应的@Service或接口上添加@Transactional即可。
