Various properties can be specified inside your application.properties
file, inside your application.yml
file, or as command line switches. This appendix provides a list of common Spring Boot properties and references to the underlying classes that consume them.
Property contributions can come from additional jar files on your classpath, so you should not consider this an exhaustive list. Also, you can define your own properties. |
This sample file is meant as a guide only. Do not copy and paste the entire content into your application. Rather, pick only the properties that you need. |
