为什么即使抛出异常数据也没有从数据库回滚我设置了rollbackFor = Exception.class，当第二次访问被放入数据库时它仍然没有回滚数据 .
@EnableTransactionManagement
@Service
public class VisitService {
private final static Logger logger = LoggerFactory.getLogger(VisitService.class);
private final VisitRepository visitRepository;
public VisitService(VisitRepository visitRepository) {
this.visitRepository = visitRepository;
}
public List<Visit> findAllByDate(LocalDateTime date){
return visitRepository.findAllByDate(date);
}
@Transactional(isolation = Isolation.READ_COMMITTED, rollbackFor = RuntimeException.class, propagation = Propagation.REQUIRED)
public Visit save(@Valid Visit visit) {
logger.info("Inside visitService");
visit.setPayed(false);
if (visit.getPrice().intValue() > 1000)
visit.setDiscount(new BigDecimal(0.05));
else visit.setDiscount(new BigDecimal(0.00));
visitRepository.save(visit);
if(findAllByDate(visit.getDate()).size()>1)
throw new RuntimeException();
return null;
}
}
尝试配置到事务
@Configuration
@ConditionalOnClass({PlatformTransactionManager.class})
@AutoConfigureAfter({JtaAutoConfiguration.class, HibernateJpaAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class, Neo4jDataAutoConfiguration.class})
@EnableConfigurationProperties({TransactionProperties.class})
public class TransactionAutoConfiguration {
}

有一个带有默认注释的visitRepository
VisitRepository：
public interface VisitRepository extends Repository<Visit, Integer> {
Visit save(Visit visit) throws DataAccessException;
List<Visit> findByPetId(Integer petId);
Visit findById(Integer visitId);
@Transactional(readOnly = true)
List<Visit> findAllByDate(LocalDateTime date);
Visit findByDate(LocalDateTime date);
}
