What is the difference between a application.properties file and a application.yml file?

The benefits of the Yml file, the natural tree structure, at a glance, is essentially the same as the properties.

Many of the official demos are configured with YML files.

Note the point:

1, the original key, such as Spring.jpa.properties.hibernate.dialect, press "." Split, all into a tree-like configuration

2,key after the colon, must follow a space

3, delete the original application.properties. Then be sure to execute the maven-x clean install
