In this chapter we learned how to:

• Add Spring Boot Developer Tools (DevTools) to our project.

• Automatically restart the application while making live changes to the code.

• Flip certain properties to stop caching when used in developer mode.

• Peek at Boot’s built-in support for LiveReload.

• Configure stack traces that would cross thread boundaries.

• Use Reactor’s logging operators to log both information and Reactive Streams signals.

• Hook up BlockHound, Reactor’s tool for spying blocking calls, even in the JDK.
