Logging - message life story

[kelumt]

Hi Guys.

i have a requirement in my Spring integration application to log all the events in a log.

For example.
message payload __________________
message entered to channel channel1.
message is entered to router router1.
message redirects to channel channel2 from router router1
---
---

i tried using <message-history/> with <logging-channel-adapter .../> but it provides only the information. can not customize to a proper logging story.

Do you guys have any idea about this?

thanks,
kelum

Hi

Your task can be solved with this one: Wire Tap

Take care,

For unit tests I have used <message-history/> and the following code to verify the route taken was correct and in order. Perhaps you can get the information in the same way I did and create your custom logging.

        MessageHistory mh = MessageHistory.read(message);
        assertThat(mh.size(), is(equalTo(13)));

        int index = 0;
        Properties props = TestUtils.locateComponentInHistory(mh, "ws-rawInboundChannel", index);
        assertThat(props, is(notNullValue()));

        props = TestUtils.locateComponentInHistory(mh, "enrichWithTransactionId", ++index);
        assertThat(props, is(notNullValue()));

Hi Wrangler,

really thanks for the help. i was able to use <message-history/> feature and create custom log using groovy as follows.

<int:service-activator id="logger" input-channel="errorChannel">
     <groovy:script>
	   headers.history.each { println it }
	   println '=' * 80
     </groovy:script>
</int:service-activator>

But i feel its not sufficient and i wanted to do some thing like you did in above code. So we have greater control over it. But i couldn't find a way of instantiating MessageHistory object as you did in your code. Can you please help me to find a way to instantiate MessageHistory object inside a POJO?

Thanks,

I went to a POJO which has a Message object as a parameter and instantiated the MessageHistory object:

        MessageHistory history = MessageHistory.read(mssage);
        for (int i = 0; i < history.size(); i++) {
            Properties properties = history.get(i);
            // could use properties.get("type") to filter what to log
            // could use properties.get("timestamp") to log dts
            logger.debug("history: " + properties.get("name"));
        }
