我越来越无法获取JDBC连接异常

标签： spring hibernate kotlin spring-data-jpa

我正在运行带有休眠和spring-data的spring-boot应用程序。我有以下方法：

@Service
class SomeService(private val repository : SomeRepository){

  fun someEndPoint(request: Request, Id: Long): UUID? {

      return try {

          val enNumber = repository.callEncrypt(request.accountNumber)

          val entity = SomeEntity().apply{
            this.id = Id
            this.enNumber = enNumber
          }

          repository.save(entity)


      } catch (e: Exception) {
          LOGGER.error("someEndPoint",e)
          throw e
      }
  }

}

当我第四次运行此方法时，出现“无法获取JDBC连接”异常。我怀疑当我调用存储过程“ callEncrypt”时，休眠不会在作业完成后释放连接，因为如果我删除该行，则应用程序运行正常，由于休眠正在处理事务，因此无法手动关闭连接（而且没有理由这样做），所以我已经坚持了一段时间，而且我不知道会发生什么。

奇怪的是，当我使用sp_who过程在sql服务器中寻找活动连接时，没有活动连接，而我现在唯一的解决方案是重新启动应用程序。如果我重新启动应用程序，一切将再次正常运行，直到我再次第四次运行此功能为止，因此很明显，休眠状态永远不会释放连接。

这是完整的堆栈跟踪：

这是与数据源相关的数据源配置：

database-name: *******
persistence-name:**********
driver-class-name: com.microsoft.sqlserver.jdbc.SQLServerDriver
max-connection-pool-size: 5
dialect: org.hibernate.dialect.SQLServer2012Dialect
show-sql: true
connection-pool-name: ************
user-name: *********
password: *******
port: ****
server: **************

这是存储库的代码：

@Repository
interface SomeRepository : CrudRepository<SomeEntity, Int> {

  fun save(someEntity: SomeEntity): SomeEntity

  @Procedure("spEncrypt")
  fun callEncrypt(bankAccountNumber: String?): Array<Byte>
}

这是实体的代码：

@Entity
@EntityListeners(AuditingEntityListener::class)
@Immutable
@NamedStoredProcedureQueries(
NamedStoredProcedureQuery(name = "SomeEntity.SpEncrypt",
        procedureName = "spEncrypt",
        parameters =[
            StoredProcedureParameter(mode = ParameterMode.IN, name = "accountNumber", type = String::class),
            StoredProcedureParameter(mode = ParameterMode.OUT, name = "enNumber", type = Byte::class)
        ]
))
class SomeEntity (){
 @Id
 @GeneratedValue(strategy = GenerationType.IDENTITY)
 @Column(name = "Id", insertable = true, updatable = false, nullable 
 =false)
 var servicingPaymentsAddOnetimeId: Long = 0L,
 @Column(name = "enNumber", insertable = true, updatable = false, 
 nullable = 
 false)
 var enNumber: Long = 0L
}

任何帮助将不胜感激。

尝试了几种方法一段时间后，我发现了两种方法可以使它起作用。

  1. 通过EntityManagerFactory创建一个新的EntityManager并使用EntityManager .close（）方法。

  2. 只需按照@Procedure annotation orphaning database connections (spring-data-jpa)中的建议使用@Transactional注释对存储库方法进行注释。我知道存储库不是放置@Transactional批注的最佳位置，但它的工作原理就像是魅力。

也许您可能希望将此帖子标记为重复，但是无论如何，我的第一个解决方案似乎也可以正常工作。

谢谢！

答案 1 :(得分：0)

@RubenFrancoD，我尝试了您的第二种方法，即@Transactional，它有效，但仅在一定程度上起作用，然后错误不断出现。

对我有用的东西

我的用例：
我正在运行与DB（Oracle 12c）的并行连接，以测试是否从序列中获得了不同的序列值。随着并行连接的增加，有时我会收到“ ORA-12519，TNS：找不到合适的服务处理程序”

经过数小时的故障排除，有效的方法：

 1. ALTER system SET SESSIONS=XXX SCOPE=SPFILE;

注意：逐步增加XXX（例如+200左右），因为如果将其增加到太高的值，您将无法启动Oracle实例，因为它无法支持！！
 2.提交;
 3.重新启动数据库。注意：不要忘记重新启动数据库，以使更改在SPFILE中生效。
 4.最后查询以查看我的更改，即limit_value：

select resource_name, current_utilization, max_utilization, limit_value
from v$resource_limit
where resource_name = 'processes';
