我已经设置了一个ExpressionEvaluatingRequestHandlerAdvice＆＃34;转发＆＃34;成功（对日志）或失败（返回消息库）的有效负载。 虽然我的服务运行正常一段时间并正确轮询配置的jdbc通道消息存储，但在处理1000条消息后会抛出以下异常。

看起来有一些已经由Sftp处理程序处理完的消息ID的缓存。我是否正确处理了Integration Config的弹簧整合流程？
答案 0 :(得分：0)
你的问题在这里：
messageStore.setUsingIdCache(true);
请参阅其JavaDocs：
* <p>Consider using this property when polling the database transactionally
* using multiple parallel threads, meaning when the configured poller is configured
* using a task executor.</p>
* <p>The issue is that the {@link #pollMessageFromGroup(Object)} looks for the
* oldest entry for a giving channel (groupKey) and region ({@link #setRegion(String)}).
* If you do that with multiple threads and you are using transactions, other
* threads may be waiting for that same locked row.</p>
* <p>If using the provided {@link OracleChannelMessageStoreQueryProvider}, don't set {@link #usingIdCache}
* to true, as the Oracle query will ignore locked rows.</p>
1000限制了此查询的气泡：
public String getPriorityPollFromGroupExcludeIdsQuery() {
return "SELECT %PREFIX%CHANNEL_MESSAGE.MESSAGE_ID, %PREFIX%CHANNEL_MESSAGE.MESSAGE_BYTES from %PREFIX%CHANNEL_MESSAGE " +
"where %PREFIX%CHANNEL_MESSAGE.GROUP_KEY = :group_key and %PREFIX%CHANNEL_MESSAGE.REGION = :region " +
"and %PREFIX%CHANNEL_MESSAGE.MESSAGE_ID not in (:message_ids) " +
"order by MESSAGE_PRIORITY DESC NULLS LAST, CREATED_DATE, MESSAGE_SEQUENCE FOR UPDATE SKIP LOCKED";
}
注意not in (:message_ids)。这就是Oracle通过1000：http://dbaparadise.com/2016/07/limitations-of-the-in-clause-in-oracle-ora-01795/
