Question

我们需要在基于Spring Integration的控制器模块中增加传入和传出JMS消息的可追溯性（添加trace-id和spell-id）。谁能帮助我使用可用于此目的的拦截器，该拦截器可以拦截进入JMS队列的所有请求以及将发送到队列的所有请求。

下面是代码段：

            <!-- Need to trace the message once we receive in incoming_queue -->
            <int-jms:message-driven-channel-adapter id="jmsIn" channel="channel_1" 
            destination-name="incoming_queue"></int-jms:message-driven-channel-adapter>   

            <!-- Need to trace the message before we send the message to outgoing_queue -->
            <int-jms:outbound-channel-adapter id="jmsOut" 
                    channel="channel_1" connection-factory="connectionFactory"
                    destination-name="outgoing_queue"/>

谢谢

在此JavaDoc的两边都有DefaultJmsHeaderMapper：

* This implementation copies JMS API headers (e.g. JMSReplyTo) to and from
 * Spring Integration Messages. Any user-defined properties will also be copied
 * from a JMS Message to a Spring Integration Message, and any other headers
 * on a Spring Integration Message (beyond the JMS API headers) will likewise
 * be copied to a JMS Message. Those other headers will be copied to the
 * general properties of a JMS Message whereas the JMS API headers are passed
 * to the appropriate setter methods (e.g. setJMSReplyTo).

因此，如果您的trace-id和spell-id处于兼容类型：

private static List<Class<?>> SUPPORTED_PROPERTY_TYPES = Arrays.asList(new Class<?>[] {
        Boolean.class, Byte.class, Double.class, Float.class, Integer.class, Long.class, Short.class, String.class });

您很好发送和接收这些标头。

如果您想记录日志头之类的东西，您肯定可以看看ChannelInterceptor实现，以便在向JMS发送/从JMS接收之前/之后记录这些头。
