在 Spring 事务中注册一个 TransactionSynchronization 对象。注册的对象将在事务提交或回滚时被调用。

//事务提交后发消息
TransactionSynchronizationManager.registerSynchronization(new TransactionSynchronizationAdapter() {
    @Override
    public void afterCommit() {
        TeacherStatusChangeDTO teacherStatusChangeDTO = TeacherStatusChangeDTO.builder()
                .teacherChangeStatus(TeacherChangeStatusEnum.ADD.name())
                .teacherMsgDTOList(Lists.newArrayList(teacherMsgDTO))
                .build();
        teacherPublish.publishMessage(teacherStatusChangeDTO);
    }
});
