我一直在使用入站通道适配器代码工作完美，但它抛出这个特殊的例外，这我不能够解决Spring集成

我使用了一个一行映射配置的输出来实现一个轮询存储结果集的bean的对象形式。

这只是一个调试消息，而我们遍历服务来找到匹配的方法。这是良性的，没有什么可担心的。

我只是在这个问题上遇到了麻烦，而我的Spring集成项目造成了mqtt连接问题。 stacktrace有点吓人:)（特别是在我的情况下，因为我的项目在一段时间后简单地停止处理消息）。我认为这与栈跟踪有关，但显然不是。根据文档，Assert通常用于“在运行时及早明确地识别程序员错误”。看起来这只是一个内部调试消息没有？这里的堆栈跟踪真的很需要吗？ – ddewaele 2014-07-16 12:57:07

我同意这有点可怕，我已经打开了一个[JIRA问题]（https://jira.spring.io/browse/INT-3474），我们将尝试解决它。关于MQTT，我们注意到Paho客户端在连接关闭期间无限期地被阻塞。随后，我们切换（在主服务器上）使用异步客户端，以便我们始终能够执行任何操作。不知道这是否与你的问题有关，但我想我会提到它。 – 2014-07-16 13:22:54

Thx很多！现在我已经把所有的东西都放在调试模式中，看看是否有一些亮光。问题发生时将尝试进行一些线程转储。 （我想我应该看到线程转储中的阻塞问题？） – ddewaele 2014-07-16 13:35:22

您的服务激活处理程序方法“getMessageProcessStatus”无法处理接收到的输入数据类型。按照预期使用适当的数据类型。

它找不到匹配的方法，它是您在服务激活器中提供的方法名称。
