Class ProcessRegistryPropertySourceApplicationContextInitializer

java.lang.Object

io.fabric8.process.spring.boot.registry.ProcessRegistryPropertySourceApplicationContextInitializer

All Implemented Interfaces:

org.springframework.context.ApplicationContextInitializer, org.springframework.core.Ordered

public class ProcessRegistryPropertySourceApplicationContextInitializer
extends Object
implements org.springframework.context.ApplicationContextInitializer, org.springframework.core.Ordered

ApplicationContextInitializer registering ProcessRegistryPropertySource.

After you add process-spring-boot-registry jar to the classpath of your application, ProcessRegistry will be used to resolve Spring properties.

   @Value("service.invoicing.url")
   String host;
 

ProcessRegistry will be attempted to be read before regular Spring property sources (for example before the application.properties file). If the desired value will not be found in the process registry, Spring will fallback to the other property sources.

By default the following process registries are aggregated by the Spring Boot container:

ZooKeeperProcessRegistry (if curator-framework is present in the classpath) ClassPathProcessRegistry InMemoryProcessRegistry

The above basically means that Spring Boot container attempts to read properties from the Fabric8 ZooKeeper registry, then from the system properties and finally from the files located in the classpath.
