SpringBoot中在Controller中使用事务

@Autowired
private PlatformTransactionManager txManager;




DefaultTransactionDefinition def = new DefaultTransactionDefinition();
def.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED);
TransactionStatus status = txManager.getTransaction(def);
        try {

        } catch (Exception ex) {
            txManager.rollback(status);
        }
        txManager.commit(status);

        return ResponseUtil.ok(group);
