我正在读取activemq并为从activemq获取的值运行存储过程。
由于我将以常规速率运行大容量，因此我们包括Threading用于从activemq读取消息并运行存储过程。
执行此操作后，我发现JOOQ没有使用任何连接池，并且正在按顺序运行所有SQL操作。

这并不是一个与jOOQ相关的问题，而是一个与BoneCP及其默认配置相关的问题。您没有指定您希望在池中建立多少连接，因此默认值将适用 - 这可能不够。
BoneCP文档对其默认值并不具有超级特定性，但您可以轻松地从com.jolbox.bonecp.BoneCPConfig对其进行反向工程。相关属性是：
/** Min number of connections per partition. */
private int minConnectionsPerPartition = 1;
/** Max number of connections per partition. */
private int maxConnectionsPerPartition = 2;
/** Number of partitions. */
private int partitionCount = 1;
因此，默认情况下，您的连接池最多有2个连接。不太令人印象深刻。
