在Spring Boot中使用数据库事务

一：在springboot启动类中添加注释 ：@EnableTransactionManagement  

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

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

}

 

二：在相应地方加上注解：@Transactional 即可

@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;
    }
}
