jpa 报错:No EntityManager with actual transaction available for current thread

No EntityManager with actual transaction available for current thread - cannot reliably process 'remove' call

背景:

使用jpa编写删除方法时出现报错

代码：

int deleteUserByUserName(String username);

报错：

报错原因：

JPA接口deleteUserByUserName(String username)没有使用事务管理

解决办法：

在deleteUserByUserName(String username)接口上使用注解@Modifying和@Transactional

    @Modifying@Transactionalint deleteUserByUserName(String username);
