我有：

BoneCP CONNECTION_POOL = ...;
CONNECTION_POOL.getConfig().setJdbcUrl("jdbc:derby:database...;shutdown=true");
Connection connection = CONNECTION_POOL.getConnection();
connection.close();
CONNECTION_POOL.shutdown();

但是，这会导致以下异常：

3274 [com.google.common.base.internal.Finalizer] ERROR com.jolbox.bonecp.ConnectionPartition - Error while closing off internal db connection
java.sql.SQLException: Cannot close a connection while a transaction is still active.

我怎样才能避免这个异常。我已经尝试了所有我能想到的方法...

除非您运行的是 v0.8.1-beta2 或更高版本，否则请在配置中将“disableConnectionTracking”设置为 true。

请注意，在成功关闭后，您还应该期待 Derby 的 SQLException：http: //db.apache.org/derby/docs/dev/devguide/tdevdvlp40464.html
