I am trying to use Spring for the first time in an application. The general issue that comes up repeatedly is how to debug Spring. The framework is configuration heavy so traditional code debugging seems fruitless. I have no real idea how to go about troubleshooting short of turning on the debugging level logs (which are lacking) and scanning through.
Are there any general tips or tools to assist Spring debugging?

A breakpoint is a signal that tells the debugger to temporarily suspend execution of your program at a certain point in the code. To define a breakpoint in your source code, right-click in the left margin in the Java editor and select Toggle Breakpoint. Alternatively, you can double-click on this position.
The add-on also provides a Spring Boot Run/Debug Configuration that allows us to customize the debug of a single Spring Boot application. This customized view is available from all the same places as the standard Java Application configuration.

If you're using Eclipse, then get hold of the Spring IDE (available from the Eclipse Marketplace within the Help menu of Eclipse). This will provide code-completion, bean visualisation, and hot-linking to your config files.
