The AI branch shows how to configure a Java Springboot application with Application Insights. Currently the sample is only configured to show requests\responses within the app - but, does not track HTTP requests\responses with dependencies.
The steps that need to be completed are described here: https://docs.microsoft.com/en-us/azure/application-insights/app-insights-java-agent. In particular, make sure that the agent jar and the AI-Agent.xml files are located next to one another. Also, when launching the app's jar, make sure that you include "-javaagent=".
This work cannot be completed right now because there is a bug that causes an exception to be thrown when attempting to start the app. When this issue is fixed, this sample needs to be updated accordingly to track dependencies: microsoft/ApplicationInsights-Java#506
