Simplify Java editing YML (YAML) format configuration file operation

In recent projects, you need to use Java to modify the configuration file of springboot, and you need to add or modify the value of a certain attribute. Snakeyaml was used to edit the multi-level structure.yamlWhen it comes to files, the operation is relatively complicated, so it has been simplified, without having to do special processing every time, and uses a processing method similar to properties files.
