Searching the internet for a lot of articles about spring boot using the devtools issue, it is said that the problem of unsuccessful is mainly the following two points:

1. Tick the Build Project automatically option in Settings->build,execution,deployment->compiler:

2, press ctrl+shift+alt+/, combination key, select 1. Registry, check compiler.automake.allow.when.app.running

Then, I try to will need to heat the package path, forcibly use additional-paths: configuration, found in the change, idea has re-release action, I thought I can, happy too early, the new code is still not updated, it seems that this speculative approach or not.

Finally, I finally found the problem, which is not mentioned on the Internet, every time I start the project, are using Gradle->tasks->application->bootrun

The problem arises here, if you use the project's startup configuration directly, such as:

The Gebb has come into effect. Ha

Guessing should be the result of Gradle startup and the project's own startup configuration!
