我正在使用带有Spring Boot 1.4.4.RELEASE和spring-cloud-dependencies的AMQP支持的通道。直到Brixton.SR6，一切正常。我在项目中唯一改变的是Brixton.SR6到Brixton.SR7（注意我也尝试了所有Camden版本，我遇到了同样的问题）我开始得到：

我的有效负载是一个可序列化的对象并且启用了调试（在两种情况下，即Brixton.SR6和Brixton.SR7，我可以看到：
o.s.messaging.MessageHeaders : Ignoring non-serializable message headers: [currentSpan, X-Current-Span]
有没有人遇到类似的问题，并找到了升级到Brixton.SR7或Camden的方法。
我尝试发送给Action.FieldBackup的消息如下所示：
o.s.i.amqp.channel.PollableAmqpChannel : preSend on channel 'Action.FieldBackup', message: GenericMessage [payload=uk.gov.ons.ctp.response.action.message.instruction.ActionInstruction@2868ea3c, headers={amqp_receivedDeliveryMode=PERSISTENT, amqp_receivedExchange=action-outbound-exchange, amqp_deliveryTag=394, X-Message-Sent=true, amqp_redelivered=true, messageSent=true, spanTraceId=15090187c236028f, spanId=8eff5c3a7c511e5b, amqp_receivedRoutingKey=Action.Field.binding, X-B3-SpanId=8eff5c3a7c511e5b, currentSpan=[Trace: 15090187c236028f, Span: 8eff5c3a7c511e5b, Parent: 15090187c236028f, exportable:false], X-B3-Sampled=0, X-B3-TraceId=15090187c236028f, id=8e4b81b8-17d0-1d15-d961-fe2b4d0e9cf5, amqp_consumerTag=amq.ctag-EXgeAZXQ5fGy8fUdHPdapQ, X-Current-Span=[Trace: 15090187c236028f, Span: 8eff5c3a7c511e5b, Parent: 15090187c236028f, exportable:false], spanSampled=0, contentType=text/xml, timestamp=1487262992385}]
在异常抛出ListenerExecutionFailedException之前，我可以看到： o.s.messaging.MessageHeaders：忽略不可序列化的消息头：[currentSpan，X-Current-Span]
我的xml配置如下：
<bean id="actionInstructionListenerContainer" class="org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer">
<property name="connectionFactory" ref="connectionFactory" />
<property name="queueNames" value="Action.Field" />
<property name="concurrentConsumers" value="${messaging.consumingThreads}" />
<property name="prefetchCount" value="${messaging.prefetchCount}" />
<property name="txSize" value="${messaging.txSize}" />
<property name="channelTransacted" value="true" />
<property name="transactionManager" ref="transactionManager" />
</bean>
<!-- Xml msg is taken off the queue Action.Field and put on the channel actionInstructionXml -->
<int:channel id="actionInstructionXml" />
<bean id="simpleMessageConverter" class="org.springframework.amqp.support.converter.SimpleMessageConverter" />
<int-amqp:inbound-channel-adapter id="actionInstructionInboundAmqp" listener-container="actionInstructionListenerContainer"
message-converter="simpleMessageConverter" channel="actionInstructionXml" />
<!-- Xml validated against the inbound schema -->
<int:channel id="actionInstructionInvalidXml" />
<int-amqp:outbound-channel-adapter id="invalidActionInstructionOutboundAmqp" channel="actionInstructionInvalidXml" exchange-name="action-invalid-exchange" routing-key="Action.ActionInstruction.binding" />
<!-- Option to be used in Debug/Test: throw-exception-on-rejection="true" -->
<int-xml:validating-filter id="actionInstructionValidator" input-channel="actionInstructionXml"
output-channel="actionInstructionXmlValid" schema-location="classpath:xsd/actionInstruction.xsd" discard-channel="actionInstructionInvalidXml"/>
<!-- The now validated xml is transformed into the jaxb generated object model -->
<!-- To mark the channel as "pollable", set the "message-driven" property to "false" -->
<int-amqp:channel id="Action.FieldBackup" message-driven="false" connection-factory="connectionFactory"
channel-transacted="true" transaction-manager="transactionManager" tx-size="${messaging.txSize}"
concurrent-consumers="${messaging.consumingThreads}" prefetch-count="${messaging.prefetchCount}" />
<int-xml:unmarshalling-transformer
input-channel="actionInstructionXmlValid" output-channel="Action.FieldBackup"
unmarshaller="actionInstructionMarshaller" />
答案 0 :(得分：1)
我们正在https://github.com/spring-cloud/spring-cloud-sleuth/issues/523的修复工作。虽然实际上已经在https://jira.spring.io/browse/SPR-15262中完成了。
解决方法如下：
public class ImmutableMessageInterceptor extends ChannelInterceptorAdapter {
@Override
public Message<?> preSend(Message<?> message, MessageChannel channel) {
MessageHeaderAccessor headers = MessageHeaderAccessor.getMutableAccessor(message);
return new GenericMessage<Object>(message.getPayload(), headers.toMessageHeaders());
}
}
您必须申请加入Action.FieldBackup AMQP支持的频道。按摩将从可变挂钩的左侧免费。
