Annotation Type ConfigMapping

@Documented
 @Target(value={FIELD,PARAMETER,TYPE})
 @Retention(value=RUNTIME)
 @Experimental(value="ConfigMapping API to group configuration properties")
public @interface ConfigMapping

This annotation may be placed in interfaces to group configuration properties with a common prefix.

Example

 @ConfigMapping(prefix = "server")
 public interface Server {
     public String host(); // maps the property name server.host
 
     public int port(); // maps to the property name server.port
 }
 

This annotation is also used in CDI aware environments to scan and register Config Mappings. Otherwise, Config Mapping interfaces require registration via SmallRyeConfigBuilder.withMapping(java.lang.Class, java.lang.String).
