数据库连接将打开，直到http请求未完成

Question

我有使用JPA和Hibernate作为ORM的spring-boot应用程序。我正在使用Hikaricp进行连接池。因此，我有一个api，可以从数据库中获取一些记录，并应用一些业务逻辑并将结果返回给客户端。由于业务逻辑需要完成繁重的任务（调用另一个api）。

我期望数据库连接应该返回到池中，因为成功获取了记录，并且与该连接无关，但是连接仍处于打开状态（HikariCP导致连接泄漏（leakDetectionThreshold = 5000））

Hikari配置。

hikari: idleTimeout: 10000 connectionTimeout: 60000 maximumPoolSize: 10 minimumIdle: 2 poolName: gor-srms leakDetectionThreshold: 5000

数据库配置类

@配置 @EnableTransactionManagement @EnableJpaRepositories（entityManagerFactoryRef =“ srmsEntityManagerFactory”，transactionManagerRef =“ srmsTransactionManager”，basePackages = {“ com.gor.platform.srms.service.dao”}）

public class SrmsDatabaseConfig {
@Autowired
private Environment environment;

@Autowired
JpaVendorAdapter jpaVendorAdapter;

@Bean(name = "srmsDataSource")
public DataSource dataSource() {
    final HikariDataSource dataSource = new HikariDataSource();
    dataSource.setDriverClassName(environment.getProperty("srms.db.driver"));
    dataSource.setJdbcUrl(environment.getProperty("srms.db.url"));
    dataSource.setUsername(environment.getProperty("srms.db.username"));
    dataSource.setPassword(environment.getProperty("srms.db.password"));
    dataSource.setIdleTimeout(Long.valueOf(environment.getProperty("hikari.idleTimeout")));
    dataSource.setConnectionTimeout(Long.valueOf(environment.getProperty("hikari.connectionTimeout")));
    dataSource.setMaximumPoolSize(Integer.parseInt(environment.getProperty("hikari.maximumPoolSize")));
    dataSource.setPoolName(environment.getProperty("hikari.poolName"));
    dataSource.setMinimumIdle(Integer.parseInt(environment.getProperty("hikari.minimumIdle")));
    dataSource.setLeakDetectionThreshold(Long.valueOf(environment.getProperty("hikari.leakDetectionThreshold")));

    return dataSource;
}

@Bean(name = "srmsEntityManagerFactory")
public EntityManagerFactory entityManagerFactory() {
    final LocalContainerEntityManagerFactoryBean lef = new LocalContainerEntityManagerFactoryBean();
    lef.setDataSource(dataSource());
    lef.setJpaVendorAdapter(jpaVendorAdapter);
    lef.setPackagesToScan(environment.getProperty("srms.entitymanager.packagesToScan"));
    lef.setPersistenceUnitName(environment.getProperty("srms.hibernate.unit_name"));
    lef.afterPropertiesSet();
    return lef.getObject();
}

@Bean(name = "srmsTransactionManager")
public PlatformTransactionManager transactionManager() {
    return new JpaTransactionManager(entityManagerFactory());
}

@Bean(name = "srmsEntityManager")
public EntityManager entityManager() {
    return entityManagerFactory().createEntityManager();
}

}

存储库类

public interface ServiceRequestDao extends Dao<MServiceRequest, Long> {
@Query(value = "Native query.....", nativeQuery = true)
Long getParentId(@Param("childId") Long childId);

}
