Class PreferenceContext

  • All Implemented Interfaces:
    org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.config.BeanFactoryPostProcessor, org.springframework.core.Ordered, org.springframework.core.PriorityOrdered
    public class PreferenceContext
extends org.springframework.beans.factory.config.PropertyPlaceholderConfigurer
    Central configuration for OMERO properties from (in order):
    • Any injected Properties instances
    • Java System.getProperties()
    • Any configured property files
    As of OMERO 4.2, server configurations are not stored in Java's Preferences API but in an IceGrid xml file under etc/grid of the server installation. The properties are set in the config file on node startup, for example in var/master/servers/Blitz-0/config/config. When the Java process starts, ome.services.blitz.Entry places the values in {#link System.getProperties().
    Since:
    3.0-Beta3
