Spring Boot and external configurations

Boot external config is what you are looking for.

Especially it mentions:

SpringApplication will load properties from application.properties files in the following locations and add them to the Spring Environment:

• A /config subdir of the current directory.
• The current directory
• A classpath /config package
• The classpath root

So I would say adding the config folder on classpath is good step. Them it should find application.properties and load it automatically.

For different config files I use:

@Configuration@EnableAutoConfiguration@PropertySource({                 "classpath:path/some.properties",                 "classpath:another/path/xmlProperties.xml"                })public class MyConfiguration {  // ...}

Edit:As Dave pointed out (Thank Dave!) there is either -cp or -jar, so you can't add it to classpath like that. But there are options. This should help you to solve the problem: Call "java -jar MyFile.jar" with additional classpath option.

Additionally @PropertySource doesn't require the resources to be classpath resources if I'm not mistaken.

It should also be mentioned that there is a spring.config.location parameter that allows one to specify a file system / classpath location for externalized configuration files. This is documented in the following section of the Spring Boot reference guide:
