    • IGNORE_BACKGROUNDPREINITIALIZER_PROPERTY_NAME

      public static final String IGNORE_BACKGROUNDPREINITIALIZER_PROPERTY_NAME
      System property that instructs Spring Boot how to run pre initialization. When the property is set to true, no pre-initialization happens and each item is initialized in the foreground as it needs to. When the property is false (default), pre initialization runs in a separate thread in the background.
