Class NCSpringModelFactory

  • All Implemented Interfaces:

    public class NCSpringModelFactory
    extends Object
    implements NCModelFactory
    Factory that delegates construction of NCModels to the Spring Framework.

    This factory requires one of the following configuration properties:

    • "javaConfig" - name a class that is annotated with the Spring's Configuration annotation
    • "xmlConfig" - path to an XML files with Spring bean definitions
    Spring factory have to be specified in probe configuration. Here's a probe.conf from Names example using Spring-based factory:
     nlpcraft {
         probe {
             id = "names"
             token = "3141592653589793"
             upLink = "localhost:8201"   # Server to probe data pipe.
             downLink = "localhost:8202" # Probe to server data pipe.
             jarsFolder = null
             models = [
             modelFactory = {
                 type = "org.apache.nlpcraft.model.factories.spring.NCSpringModelFactory"
                 properties = {
                     javaConfig = "org.apache.nlpcraft.examples.names.NamesConfig"
             lifecycle = [
             resultMaxSizeBytes = 1048576
         nlpEngine = "opennlp"

    Lines 10-15 specify data model factory and its configuration properties.
