Spring boot 3 return 404 on azure app

Florent Bonamis 11 Reputation points


We are running a Hello World app on an Azure Linux app.
When we are using Spring boot 2.76, there is no problem. When we are upgrading the sprong boot version to 3.0.4 we are encountering a 404 error.
Is this related to that kind of issue?

    The solution is here.


    Solved by upgrading the ApplicationInsights Java Agent to 3.4.10

    My guess is the old agent is not compatible with jars compiled for Java 17.
