我正在尝试使用 Spring Integration 和 ActiveMQ 消息代理配置 JMS。我的出站 channel 应该由 JDBC 消息存储支持，以防止数据丢失，例如经纪人或我的应用程序离线。

到目前为止，我的配置似乎有效，但 JDBC 消息存储的行为并不像我预期的那样。如果我断开代理，发送到出站 channel 的消息将按预期保留，但在重新连接后它们保留在数据库中并且不会发送到队列。但是，我在重新连接后发送的更多消息到达队列，如果我重新启动我的应用程序，持久消息也会最终发送......

我正在使用 EcomxProducerGateway 发送消息。它将消息发送到 output_enricher_channel，后者将它们转发到 output_router，后者按负载类型将消息路由到正确的出站 channel 。

断开代理时，几秒钟后会记录几个异常。以下堆栈跟踪可能会有所帮助:

最佳答案

嗯，由于 usingIdCache="true"，这对回滚消息不起作用。消息返回到数据库，但它们不会被下一个 poll 拾取，因为它们的 id 在内存中 idCache 中。

我们提供此建议以处理已处理或回滚的消息:

<int:transaction-synchronization-factory id="syncFactory">
    <int:after-commit expression="@store.removeFromIdCache(headers.id.toString())" />
    <int:after-rollback expression="@store.removeFromIdCache(headers.id.toString())"/>
</int:transaction-synchronization-factory>

...

<int:poller id="defaultPoller" default="true" fixed-delay="500">
    <int:transactional propagation="REQUIRED" isolation="DEFAULT" 
                       synchronization-factory="syncFactory" 
                       transaction-manager="transactionManager"/>
</int:poller>

独立于 TX 结果的消息 id 从 idCache 中删除。在您的情况下，它将准备好再接受一次轮询。

在 Reference Manual 中查看更多信息. JdbcChannelMessageStore#setUsingIdCache 上的 JavaDocs 显示相同。

关于java - Spring 与 JMS + ActiveMQ 集成 : Messages remain in JDBC Message Store after reconnect，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/29913956/
