Class Config

  • public abstract class Config
extends java.lang.Object
    A injectable singleton config that has default implementation based on FileSystem json files. It can be extended to other sources (database, distributed cache etc.) by providing another jar in the classpath to replace the default implementation. Config files are loaded in the following sequence: 1. resource/config folder for the default 2. externalized directory specified by light-4j-config-dir In docker, the config files should be in volume and any update will be picked up the next day morning.
