Application insights Spring boot starter showing circular reference error?

[ken-hum]

Hi all, I am trying to use application insights spring booter as part of my spring application. I believe to have correctly created the Application Insight resource in Azure Portal. Also the instrumentation key is properly put in the application.properties.

Spring Version: :: Spring Boot :: (v1.5.10.RELEASE)
Java = open JDK 1.8

Upon boot, i get this? Any hints?

2018-06-20T12:54:00.845,ERROR,org.springframework.boot.SpringApplication-771,main,"Application startup failed"

@ken-hum I tried to reproduce this issue on the plain springboot app with springboot 1.5.10 and jdk8 and I was not able to find this when I did mvn clean package.
Is it possible for you to upload a sample / trimmed down version of your app for further diagnosis?

[pietrobr]

I get the same error following the tutorial here: https://docs.microsoft.com/en-us/java/azure/spring-framework/configure-spring-boot-java-applicationinsights?view=azure-java-stable

[ken-hum]

i'm trimming down my app for you dhaval24, will attach shortly

[dhaval24]

@pietrobr and @ken-hum I am still not able to reproduce this . This time I exactly followed tutorial which I published word by word with SpringBoot 1.5.10 version and JDK 1.8. My application successfully starts and I am also able to see all the telemetry on the portal. I am attaching the sample app which I created here. You can try it out by inserting your instrumentation key and hit mvn clean package
and mvn spring-boot:run

[dhaval24]

demo.zip

Here is the sample app I had tried to reproduce the issue mentioned (exactly following the tutorial)

[pietrobr]

@dhaval24 Thanks very much. Your sample works. The difference with my original one is that I started with Spring version 2, but after installing with option mvn clean install -DskipTests, I was able to make it work also with version 2 of Spring. Thanks!!

[dhaval24]

@pietrobr no worries. Glad it helped

[dhaval24]

@ken-hum did you had a chance to take a look at the demo I uploaded? Please let me know if it solves your issue and we can then close this thread.

[ken-hum]

Hi dhaval24, the demo you've sent is a webapp. I am getting the error on a core-app.
We just got out from call with Rahul Gupta and Chandresh Govani (from Microsoft) talking about this issue. I will update you with a trimmed app very soon.

[dhaval24]

@ken-hum makes sense. Is your application a spring-boot rest service instead? Sorry, I am a bit confused when you say it's a core app.

And I configured logback-spring.xml to be

<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
        <pattern>
            %d{yyyy/MM/dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n

</appender>

<appender name="aiAppender"
          class="com.microsoft.applicationinsights.logback.ApplicationInsightsAppender">
</appender>

<springProfile name="dev">
    <root level="info">
        <appender-ref ref="STDOUT"/>
        <appender-ref ref="aiAppender"/>
    </root>
</springProfile>

<springProfile name="prod">
    <root level="ERROR">
        <appender-ref ref="aiAppender"/>
    </root>
</springProfile>

It shows the circular bean error.

Could you help to see what might be the issue?

[dhaval24]

@zhouchong90 are you getting the exact same issue as @ken-hum ? I am trying to reproduce the issue on my end and am still not successful. I have also configured logback in my sample project which I have uploaded in the thread and I can see all the traces coming to AI portal. My application also boots up as normal.

However one change : Instead of using <version>[2.0,)</version> in my pom.xml I have specified the exact version number of logback - <version>2.1.1</version> to avoid any sort of classpath hell. Could you please try this and let me know. If that doesn't work out I would suggest uploading a trim down version of your application to debug further.

[dhaval24]

@ken-hum thank you very much for providing the trimmed down version of the app. I will take a look soon.

[zhouchong90]

@dhaval24 Somehow changing the version made it work! And when I change it back to [2.0,), it still works correctly. I don't understand why, but thanks!

[dhaval24]

@ken-hum I have deleted your post. Please ensure that it doesn't contain any sensitive information. and by the way yes it seems that there is some circular dependency. I will debug it as soon as I get some time. It seems like this appears only when the application is not a web app.

[ken-hum]

Hi Dhaval, any updates?? thanks

[dhaval24]

@ken-hum I haven't got a chance to dig deep for the exact root cause of this issue. As soon as I have a chance to determine the root cause I will update the thread.

[dhaval24]

@ken-hum I have created a PR to fix this. It should be fixed in our next release. Thanks

[ken-hum]

Hi Dhaval24, i tried the fix from branch. The spring service is now able to start.

However, it fails right away with another error:

[dhaval24]

@ken-hum I haven't seen this before. Seems like you are having some trouble reaching the end point of AI. are you running your service under some sort of proxy? Do you face the issue in the same service that you had uploaded ?

[ken-hum]

yes. The same TrimmedStart.jar

[dhaval24]

Would you mind re-uploading it here? Apologies for any inconvenience . please remove the iKey before uploading.

[ken-hum]

In fact. I think we're good. The app actually does nothing beside startup. and then it shut down right away. So it is the expected behavior. So all is good and thanks for the fix

[dhaval24]

@ken-hum no worries. I will close this issue once we release officially. If you fine using the snapshot build from the branch please keep using it until we officially release the fix.

[dhaval24]

@ken-hum could you test in your real application if the fix works for you there and let us know?

[ken-hum]

Sure. I tried the snapshot in my app and it works OOB(out of box). At least for vital signs... Once I start testing it further such as telemetry and all and if i find any other issues, I will open another issue ticket. Thanks
