A Spring Cloud Configuration Property for discovering your configuration properties.
Add the Spring Cloud starter to your project:
<dependency>
<groupId>io.jmnarloch</groupId>
<artifactId>discovery-client-property-spring-cloud-starter</artifactId>
<version>1.0.0</version>
</dependency>Registers a custom PropertySource that allows to resolve a SpEL like expressions for ${discoveryClient.} prefix.
The underlying implementation will delegate to the registered DiscoveryClient instance allowing to resolve the
properties based on discovery registry.
Example:
spring:
data:
elasticsearch:
clusterNodes: ${discoveryClient.url(http://elasticsearch/)}Currently supported operations:
- service - returns a single service url
- url - expands the url replacing the host name and port with discovered service values, any additional information passed as the argument like the user login, path and query params will remain intact.
Notices that the property will be resolve only once during the application startup.
Currently this extension is most useful with Consul which allows you to register any arbitrary service.
