Question

我创建了一个简单的流，它公开了一个链接到REST服务的HTTP端点。 REST服务返回一个String，然后使用请求 - 响应模式将其置于JMS队列中。这个想法是放在队列中的字符串将由某个消费者使用，并且将使用Reply-To地址创建响应。所以基本上这就是同步JMS。

流程按预期工作，除非使用基本身份验证保护HTTP端点。在这种情况下，响应是：

java.io.NotSerializableException: com.sun.jersey.spi.container.ContainerResponse (org.apache.commons.lang.SerializationException). Message payload is of type: MuleResponseWriter$1

并且队列中没有消息。删除基本身份验证会导致不会抛出异常。此外，删除JMS出站端点会导致回显String，这使我相信问题出在JMS端点上。我怀疑问题出在JMS端点的响应上，因为将流中的组件设置为单向可以消除问题。我认为问题可能是端点在没有身份验证凭据的情况下向HTTP端点发送一些响应，因此失败，但我不确定如何处理此问题。

以下是我创建的流程：

有什么想法吗？

Answer 1

原来问题是jersey_response属性无法序列化，需要删除。因此，无论有效负载是什么，只要此属性在消息中，消息就无法传递给JMS出站组件。更多信息可在以下网址找到：

Answer 2

异常的原因是因为任何jersey组件都会返回一个com.sun.jersey.spi.container.ContainerResponse，在将其传播到下一个消息处理器之前需要进行转换，如here所述
