Class NCSpringModelFactory

  • All Implemented Interfaces:
    NCModelFactory
    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 = [
             "org.apache.nlpcraft.examples.names.NamesModel"
         ]
         modelFactory = {
             type = "org.apache.nlpcraft.model.factories.spring.NCSpringModelFactory"
             properties = {
                 javaConfig = "org.apache.nlpcraft.examples.names.NamesConfig"
             }
         }
         lifecycle = [
         ]
         resultMaxSizeBytes = 1048576
     }
     nlpEngine = "opennlp"
  }
