问题
I noticed a different behavior of the property spring.cloud.bootstrap.location since Spring Boot 2.x
Behavior in Spring Boot 1.x:
- Build in bootstrap.properties file inside the JAR is regarded
- Specified bootstrap.properties file is regarded
Behavior in Spring Boot 2.x:
- Build in bootstrap.properties file inside the JAR is not regarded
- Specified bootstrap.properties file is regarded
Reason is that since Spring Boot 2 the behavior of the spring.config.location configuration has been fixed and the property spring.cloud.bootstrap.location works now also as desired.
See https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.0-Migration-Guide#configuration-location
I restored the origin behavior by adding the default search locations to the property in addition spring.cloud.bootstrap.location=classpath:/,classpath:/config/,file:./,file:./config/,file:/my/special/search/location
Should there be introduced also a new property spring.cloud.bootstrap.additional-location like the spring.config.additional-location?
Hint: This is how the BootstrapApplicationListener currently works:
