Spring Integration Rabbitmq消息处于就绪状态

Question

我与rabbitmq的春季集成出现了问题。 消息被发送到队列，但最终处于就绪状态，并且消息未被确认，但使用者没有得到它们。

Thx xml配置如下所示：

在服务器上重新启动时，第一个被拾取，但是在下一个调用中，消息堆积在队列中。 您知道为什么会发生这种情况吗？

谢谢丹尼尔

编辑：

消费者代码：

public class JsonEnrichmentService implements EnrichmentService {

@Resource
private UserQueryService userQueryService;

@Resource
private SecurityContextService securityContextService;

@Override
public void processMessage(POJO record) {
    System.out.println(record);
}

这将调用具有事务注释的新服务。

以我的经验，这通常是由于侦听器线程被“卡在”用户代码中的某个地方引起的。 进行线程转储以查看侦听器线程在做什么。
