This article mainly explains "how to configure the java Spring Cloud Config environment library". The content of the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn how to configure the java Spring Cloud Config environment library.

The policy that manages this behavior is EnvironmentRepository, which serves the Environment object. This Environment is a shallow copy of the domain of Spring Environment (including propertySources as the primary function). The Environment resource is parameterized by three variables:

{application} is mapped to the client's "spring.application.name"

{profile} is mapped to "spring.profiles.active" (comma separated list) on the client; and

{label} this is a server-side feature that marks the "version" set of profiles.

The repository implementation usually behaves like a Spring Boot application loading configuration files from the "spring.config.name" equals the {application} parameter, and the "spring.profiles.active" equals the {profiles} parameter. The priority rules for profiles are the same as for regular startup applications: the active profile takes precedence over the default configuration, and if there are multiple profiles, the last one wins (for example, adding an entry to Map).

Example: the client application has this boot configuration:

Bootstrap.yml

Spring:&nBSP; application: name: foo profiles: active: dev,mysql

(typically using Spring Boot applications, these properties can also be set to environment variables or command-line arguments).

If the repository is file-based, the server creates an Environment from application.yml (shared among all clients) and foo.yml (with foo.yml first). If there are files in the YAML file that point to the Spring configuration file, then the priority of the application is higher (in the order of the configuration files listed), and if there are YAML (or properties) files specific to the profile, then these files also apply to the priority above the default value. The higher priority translates to the PropertySource listed before Environment. (these rules are the same as stand-alone Spring Boot applications.)

Thank you for reading, the above is the content of "how to configure the java Spring Cloud Config environment library". After the study of this article, I believe you have a deeper understanding of how to configure the java Spring Cloud Config environment library, and the specific use needs to be verified in practice.
