hibernate - Seam - 通过 (Session)em.getDelegate() 获取连接；

Question

我使用 Seam 框架。

如果我这样做

Session sess = (Session)em.getDelegate();
Connection conn = sess.connection();

那么这是一个新的连接吗？我是否必须手动关闭连接？

我在 Weblogic 应用服务器的循环中对此进行了测试:

    Session sess = (Session)em.getDelegate();

    for (int i=1; i<=1000; i++) {
        Connection conn = sess.connection();
        // ... 
        //conn.close();
    }

而且我从来没有在控制台中看到 Weblogic 池限制资源不足并且也不会强制将非事件连接连接到池。

来自javadoc:

Get the JDBC connection of this Session. If the session is using aggressive collection release (as in a CMT environment), it is the application's responsibility to close the connection returned by this call. Otherwise, the application should not close the connection.
