[rules-users] Problem Itegrating Spring 3.2 with Drools 6.0.0

[milen igrachev]

   Hello,
   
   I experience a problem autowiring my KieSession object into my Controller field in Spring.
   
   
   I read the Spring integration configuration part of Drools documentation and edited my Spring
   
   
   configuration as adviced. However on deploying I receive one and the same well know exception:
   
   
   

    
    "org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.kie.api.runtime.KieSession] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true), @org.kie.api.cdi.KSession(name=, value=ksession-rules)}"
    
   
   
   

   
   
   My application's web.xml defines my spring configuration entries as follows:
   

    
       
    
    
         mvc-dispatcher  
    
   
   
       ...... 
   
   
      
   
   
    
       
    
    
         mvc-dispatcher  
    
    
         /  
    
    
       
    
    
       
    
    
         contextConfigLocation  
    
    
          
    
    
        /WEB-INF/beans.xml, 
    
    
        /WEB-INF/security.xml, 
    
    
        /WEB-INF/entityManager.xml 
    
    
          
    
    
       
    
   
   
   

   
   
   As guided by Drools documentation I entered the following Drools configuration in my spring configuration (I try to put the bean both in mvc-dispatcher-servlet.xml configuration and in beans.xml the result is the same).
   
   
    
       
    
    
       
    
    
     
 
     
    
    
     
 
     
    
    
     
 
     
    
    
     
 
     
    
    
       
    
    
       
    
    
       
    
   
   
   I have this package

    "com.my.sample.drools.rulespackage"
 with
a simple and tested rule in it.
   
   
   

   
   
   In my Controller class I am trying to autowire the KieSession bean to a field as follows:
   

    
     @Controller 
    
    
     @RequestMapping(value = "/") 
    
    
     public class BaseController extends AbstractController { 
    
    
     
 
    
    
        private static final Logger log = Logger.getLogger(BaseController.class); 
    
    
     
 
    
    
        @Autowired 
    
    
        @KSession("ksession-rules") 
    
    
        KieSession mySession; 
    
   
   
       ............. 
   
   
    } 
   
   
   I tryed with @Inject instead of spring's @Autowire, the result is the same.
   
   
   

   
   
   I am using the following Drools dependencies with their versions:
   
drools-core - 6.0.0.FINAL; drools-compiler - 6.0.0.FINAL; kie-spring - 6.0.0.FINAL; (I am trying to keep it simple as my first integration try.)
   
   
   The spring version that I am using is 3.2.4.RELEASE.
   
   
   

   
   
   I debugged

    KModuleBeanFactoryPostProcessor
 and I can clearly see that an object tree with
KieModuleModelImpl,
KieBaseModelImpl,
KieSessionModelImpl,
   
   
   with the corresponding details that I entered in the configuration above (packages, name, type, etc.) is created!. However it seems that a KieSession bean is not registered
spring's container. 
   
   

   
   
   What I do wrong? Can anyone please help?
   

   
Thanks in advance!
   
Best Regards,
   
   
   Milen
