我正在尝试使用ConnectionFirst alizationCallback配置UCP PoolDataSourceImpl。这是我的配置：

private static DataSource createDataSource(Properties properties) throws SQLException, UniversalConnectionPoolException {
    UniversalConnectionPoolManager ucpm        = UniversalConnectionPoolManagerImpl.getUniversalConnectionPoolManager();
    PoolDataSource                 pds         = PoolDataSourceFactory.getPoolDataSource();
    final String                   editionName = properties.getProperty("jdbc.editionName", "ora$base");

    pds.registerConnectionInitializationCallback(new oracle.ucp.jdbc.ConnectionInitializationCallback() {
        public void initialize(Connection connection) throws SQLException {
            LOG.debug("Attempting to set edition to: {}", editionName);
            try (Statement statement = connection.createStatement()) {
                statement.executeUpdate("ALTER SESSION SET EDITION = " + editionName);
            }
            LOG.debug("Edition set to: {}", editionName);
        }
    });

    pds.setConnectionFactoryClassName("oracle.jdbc.pool.OracleDataSource");
    pds.setUser(properties.getProperty("jdbc.username"));
    pds.setPassword(properties.getProperty("jdbc.password"));
    pds.setURL(properties.getProperty("jdbc.url"));
    pds.setConnectionPoolName("demo-pool");
    pds.setInitialPoolSize(3);
    pds.setMaxPoolSize(3);
    pds.setValidateConnectionOnBorrow(true);

    LOG.debug("Created DataSource Pool");
    ucpm.createConnectionPool((UniversalConnectionPoolAdapter)pds);
    ucpm.startConnectionPool("demo-pool");

    return pds;
}

然而，从未调用过初始化方法。我将java1.7.0_51与以下Oracle jar一起使用：

ojdbc6.jar-v12.1.0.1.0 ucp. jar-v12.1.0.0.0

我已经设法使这项工作通过删除调用"checksterConnectionFirst alizationCallback"并将其替换为调用"regsterConnectionLabelingCallback"，但从我的理解，这将执行ALTER SESSION每次从池请求连接，而不是当它实际创建时。

如果您能提供帮助，让ConnectionCentalizationCallback工作，我们将不胜感激。
