Config Feature
MicroProfile Config is a solution to externalise configuration from microservices. Each individual property can be injected directly
@Inject
@ConfigProperty(name = "java.runtime.version")
private String javaVersion;You can also set a default value for it, case the config does not match the property in the context it will use the default value
@Inject
@ConfigProperty(name = "defaultProperty", defaultValue = "ALOHA")
private String defaultProperty;The config object can also be injected. Then use the getValue() method to retrieve the individual property.
@Inject
private Config config;
@GET
@Path("javaVersion")
public String getJavaVersionPropertyFromSystemProperties() {
return config.getValue("java.runtime.version", String.class);
}
