将记录保存到数据库需要太长时间

Question

我正在尝试在Spring Boot项目中将记录保存到Oracle DB。我正在从其余服务中获取输入，运行逻辑并将结果保存到DB中。在搜索日志时，我看到一些记录在10到20毫秒内被保存，但是有些记录在千毫秒内保存。我怀疑数据源池化，但我不确定。这里有什么错误吗？

JPA配置

@Configuration
@PropertySource({"classpath:application.properties"})
@EnableJpaRepositories(
        basePackages = "com.ykb.frd.fraudbase.repository.hibernate.fraud",
        entityManagerFactoryRef = "fraudEntityManager",
        transactionManagerRef = "fraudTransactionManager")
public class FraudConfiguration {
    @Autowired
    private DataSourceProperties dataSourceProperties;

    @Autowired
    private Environment env;

    @Bean
    @Primary
    public LocalContainerEntityManagerFactoryBean fraudEntityManager() {
        LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
        em.setDataSource(fraudDataSource());
        em.setPackagesToScan("com.ykb.frd.fraudbase.entity.fraud");

        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        em.setJpaVendorAdapter(vendorAdapter);

        return em;
    }

    @Primary
    @Bean
    public DataSource fraudDataSource() {
        DataSourceBuilder factory = DataSourceBuilder
                .create(this.dataSourceProperties.getClassLoader())
                .driverClassName(env.getProperty("driver-class-name"))
                .url(env.getProperty("fraud.url"))
                .username(env.getProperty("fraud.username"))
                .password(env.getProperty("fraud.password"));
        return factory.build();
    }

    @Primary
    @Bean
    public PlatformTransactionManager fraudTransactionManager() {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(fraudEntityManager().getObject());
        return transactionManager;
    }
}

存储库

@Repository
public interface FraudRequestTransactionsRepository extends CrudRepository<FraudRequestTransactionsEntity, Long> {
}

保存到数据库

long start = System.currentTimeMillis();
        BaseService service = baseServices.length > 0 ? baseServices[0] : null;
        FraudRequestTransactionsEntity fraudRequestTransactionsEntity = new FraudRequestTransactionsEntity();
        fraudRequestTransactionsEntity.setLuc(0);
        fraudRequestTransactionsEntity.setTransactionId(fraudActionsRestRequest.getTransactionId());
        if (fraudActionsRestRequest.getSenderClientNo() != null)
            fraudRequestTransactionsEntity.setClientNo(Integer.parseInt(fraudActionsRestRequest.getSenderClientNo()));
        fraudRequestTransactionsEntity.setTransactionId(fraudActionsRestRequest.getTransactionId());
        fraudRequestTransactionsEntity.setUserId(fraudActionsRestRequest.getUserId());
        fraudRequestTransactionsEntity.setChannelName(fraudActionsRestRequest.getChannel());
        fraudRequestTransactionsEntity.setProcessCode(fraudActionsRestRequest.getProcessCode());
        fraudRequestTransactionsEntity.setProcessName(fraudActionsRestRequest.getProcessName());
        fraudRequestTransactionsEntity.setRequest(requestMessage);
        fraudRequestTransactionsEntity.setTransactionStatus("FINISHED");
        fraudRequestTransactionsEntity.setSessionId(fraudActionsRestRequest.getSessionId());
        Calendar date = Calendar.getInstance();
        fraudRequestTransactionsEntity.setTransactionDate(date.getTime());
        fraudRequestTransactionsEntity.setTransactionMillisecond(date.get(Calendar.MILLISECOND));
        fraudRequestTransactionsEntity.setAmount(fraudActionsRestRequest.getTlAmount());
        fraudRequestTransactionsEntity.setCurrency(fraudActionsRestRequest.getSenderCurrencyCode());
        fraudRequestTransactionsEntity.setDeviceId(fraudActionsRestRequest.getDeviceId());
        fraudRequestTransactionsEntity.setReceiverAccountNo(fraudActionsRestRequest.getReceiverAccountNo());
        fraudRequestTransactionsEntity.setTransactionType(fraudActionsRestRequest.getFraudTransactionsMapEntity().getTransactionType());
        fraudRequestTransactionsEntity.setSenderCardNo(fraudActionsRestRequest.getSenderCreditCardNumber());
        fraudRequestTransactionsEntity.setTransactionSequenceNo(Long.toString(fraudActionsRestRequest.getTransactionSequenceNo()));
        //TODO zeynep & berkin : bu alanları almamız gereken yerlere bakılacak
        /*fraudRequestTransactionsEntity.setSubScriberNo(fraudActionsRestRequest.get);
        if(fraudActionsRestRequest.getFraudTransactionsMapEntity().getTransactionType().equalsIgnoreCase(FalconUtil.RBTRAN)){

            fraudRequestTransactionsEntity.setReceiverCardNo(((RbtranServiceInputModel)service).);
            fraudRequestTransactionsEntity.setReceiverPhoneNo(((RbtranServiceInputModel)service).);
        }*/

        fraudRequestTransactionsRepository.save(fraudRequestTransactionsEntity);
        log.info("[{}] REQ DB Yazma Süresi {}", fraudActionsRestRequest.getTransactionId(), System.currentTimeMillis() - start);
