Java 在Spring集成中处理异常时遇到问题

java error-handling rabbitmq spring-integration

Java 在Spring集成中处理异常时遇到问题,java,error-handling,rabbitmq,spring-integration,Java,Error Handling,Rabbitmq,Spring Integration,我是spring集成新手，对如何将错误消息发送到指定的错误队列感到困惑。我希望错误消息是原始消息上的一个标头，并以单独的队列结束。我了解到这可以通过头enricher实现，我尝试实现它，但错误队列中没有显示任何内容 另外，我是否需要一个单独的异常处理类，以便将错误消息发送到错误队列，或者我是否可以在转换方法中抛出异常 以下是我的xml配置： <beans xmlns="http://www.springframework.org/schema/beans" xmlns:int="ht

我是spring集成新手，对如何将错误消息发送到指定的错误队列感到困惑。我希望错误消息是原始消息上的一个标头，并以单独的队列结束。我了解到这可以通过头enricher实现，我尝试实现它，但错误队列中没有显示任何内容

另外，我是否需要一个单独的异常处理类，以便将错误消息发送到错误队列，或者我是否可以在转换方法中抛出异常

以下是我的xml配置：

QualityScorer类（由transformer调用）：

总之，程序应该从队列接收预加载的消息，对其进行转换并将其发送到第二个队列，如果预加载的消息中提供了源，则程序会成功地执行此操作。我正在尝试处理错误，并使其作为消息头发送到错误队列。这个问题让我沮丧了一段时间，所以非常感谢您的帮助
