Difference bootstrap / application of
characteristic
Spring Cloud Spring Boot built on, there are two context Spring Boot, a bootstrap is, the other is a file application, bootstrap context of the application is the parent, i.e. bootstrap loading precedence applicaton. bootstrap mainly used from additional resources to load the configuration information, you can decrypt the property outside the local configuration file. Both share an environment context, it is the source of any external properties Spring application. Inside the priority attribute bootstrap loading, default they can not be covered with the same configuration locally.
In short, in contrast to the application configuration file,
- boostrap loaded by the parent ApplicationContext, loading priority than the applicaton
- boostrap inside can not be overwritten
