在Spring Boot中使用数据库事务

@EnableDiscoveryClient
@SpringBootApplication
@EnableFeignClients
@EnableTransactionManagement
public class DeploymentServiceApplication {

public static void main(String[] args){
SpringApplication.run(DeploymentServiceApplication.class, args);
}

}

@Service
public class DemoServiceImpl implements DemoService {
@Autowired
PersonRepository personRepository;

@Transactional(rollbackFor = {IllegalArgumentException.class})
@Override
public Person savePersonWithRollBack(Person person) {
Person p = personRepository.save(person);
if (person.getName().equals("sang")) {
throw new IllegalArgumentException("sang 已存在，数据将回滚");
}
return p;
}

@Transactional(noRollbackFor = {IllegalArgumentException.class})
@Override
public Person savePersonWithoutRollBack(Person person) {
Person p = personRepository.save(person);
if (person.getName().equals("sang")) {
throw new IllegalArgumentException("sang已存在，但数据不会回滚");
}
return p;
}
}
