Hibernate 使用SimpleAsyncTaskExecutor时数据库连接泄漏

我有一个带有JpaPagingItemReader的Spring批处理应用程序，它使用SimpleAsyncTaskExecutor。 我使用AbstractRoutingDataSource可以使用2个数据源

我的数据源配置来自指南

public DataSource dataSource() {
    final Map<Object, Object> targetDataSources = new HashMap<>();

    final DataSource readDataSource = buildDataSource(READ_HIKARI_POOL, readProperties);
    final DataSource writeDataSource = buildDataSource(WRITE_HIKARI_POOL, writeProperties);

    targetDataSources.put(RoutingDataSource.READ, readDataSource);
    targetDataSources.put(RoutingDataSource.WRITE, writeDataSource);

    return new RoutingDataSource(targetDataSources, readDataSource);
  }

  private DataSource buildDataSource(final String poolName,
                                     final AuroraProperties auroraProperties) {
    final HikariConfig hikariConfig = new HikariConfig();

    hikariConfig.setPoolName(poolName);
    hikariConfig.setJdbcUrl(auroraProperties.getUrl());
    hikariConfig.setUsername(auroraProperties.getUsername());
    hikariConfig.setPassword(auroraProperties.getPassword());
    hikariConfig.setDriverClassName(auroraProperties.getDriver());
    hikariConfig.setLeakDetectionThreshold(LEAK_DETECTION_THRESHOLD_MS);
    hikariConfig.setMaximumPoolSize(MAX_POOL_SIZE);

    return new HikariDataSource(hikariConfig);
  }

及

Jpa分页项目读取器的代码为默认值。 一切正常，但我有一个连接泄漏。 每次作业后，我都有一个连接在Jpa PagingItemReader上泄漏

final List<Model> queryResult = query.getResultList();

final List queryResult=query.getResultList（）；

来自泄漏连接的stacktrace是
