  • All Implemented Interfaces:
    ConfigSource
    public class HoconMpConfigSource
extends Object
implements ConfigSource
    MicroProfile ConfigSource that can be used to add HOCON/JSON files from classpath or file system using the ConfigProviderResolver.getBuilder().

    The HOCON/JSON file is transformed to a flat map as follows:

    Object nodes

    Each node in the tree is dot separated. 

     server = {
   host = "localhost"
   port= 8080
 }
    Will be transformed to the following properties: 
     server.host=localhost
 server.port=8080
    List nodes (arrays)

    Each node will be indexed (0 based) 

     providers =
   [{abac = {enabled = true}}]
 names = [
   first
   second
   third
 ]
    Will be transformed to the following properties: 
     providers.0.abac.enabled=true
 names.0=first
 names.1=second
 names.2=third
