java - Spring 3.x - Bean named 'zoneManagerDelegate' must be of type [com.ms.adsp.delegate.sapi.ZoneManagerDelegate], but was actually of type [$Proxy20] -


i have huge complex spring project. when added new class:

@service("zonemanagerdelegate")   @cached(keygeneratorclass=serviceglobalkeygenerator.class,datawrapperclass=servicedelegatedatawrapper.class, tags = {"service", "sapi"})   public class zonemanagerdelegate extends sapidelegate<zonemanagerws> {      public zonemanagerdelegate(){         super(zonemanagerws.class);     }      @cached     public object[] getzones(salesusercontext usercontext) throws salesapiexception {         return getws().getzones(usercontext);     } }

and run project, encountered error output:

usage looks this:

@component   public class objectfinderextfactory {      @resource(name="zonemanagerdelegate")     private zonemanagerdelegate zonemanagerdelegate;  ...

}

when remove @cached annotation in zonemanagerdelegate - it's working fine. other delegates extends sapidelegate - work fine too.

additional information:

public abstract class sapidelegate<t> implements applicationlistener<environmentreloaded> {  private static final logger logger = logger.getlogger(sapidelegate.class);  private t wsinstance;  private final class<t> wsclass;  public sapidelegate(class<t> wsclass){     this.wsclass = wsclass; }  @override public synchronized void onapplicationevent(environmentreloaded appreloaded) {     wsinstance = null;     logger.debug("sales api client invalidated: " + wsclass.getname()); }  /**  * returns webservice client object  */ protected synchronized  t getws() {     try {         if (wsinstance == null) {             wsinstance = clientfactory.createclient(wsclass, "adsalespro");             logger.debug("sales api client created: " + wsclass.getname());         }         return (t) wsinstance;     } catch (exception e) {         throw new sapiexception(e);     } }

}

version:
spring 3.2.0
apache-tomcat-6.0.36

any ideas? thanks.

to me seems problem lays in not programming against interfaces.

try define interface this:

public interface zonemanagerdelegateinterface  {      public object[] getzones(salesusercontext usercontext) throws salesapiexception }

and implement zonemanagerdelegate.
use referring it's interface:

@component   public class objectfinderextfactory {      @resource(name="zonemanagerdelegate")     private zonemanagerdelegateinterface zonemanagerdelegate;  ...

update

another solution using cglib proxies instead of jdk dynamic proxies. can forced in spring configuration. note need cglib on classpath (not true since spring 3.2.0).

here interesting comparison of cglib proxies , jdk dynamic proxies
