Only the code will not lie, how to view its default configuration for each frame through the spring boot source

I found a lot of development for the source to see a kind of fear, in fact, most of the excellent source writing is quite intuitive, a lot of times, you search for some of the things are not necessarily true, but the source is certainly not fake, after all, no matter how you think, it is there, what it means is what meaning, Do not change with human subjectivity.

For example, the default configuration for the open source framework for spring boot is under this package, and you want to know what the default configuration of the framework you are using in spring boot can be found directly under this package, which is more intuitive and clear than what you're searching for, after all, what you're searching for may not be consistent with your version.

Org.springframework.boot.autoconfigure
To give you a little trick, spring Boot has a strict naming convention, and its default configuration class is basically the end of properties
As an example:

Jacksonproperties (Jackson is the Spring boot default JSON serialization tool)
