java - Cannot use Components/Service/Repository in Controller class -
i have configurated dao layer(i've created test check it), , integrate project spring mvc.
i've added configuration:
@configuration @enablewebmvc @componentscan(basepackages = "com.szymon.controller") public class webmvcconfig { @bean public viewresolver viewresolver() { internalresourceviewresolver viewresolver = new internalresourceviewresolver(); viewresolver.setviewclass(jstlview.class); viewresolver.setprefix("/web-inf/views/"); viewresolver.setsuffix(".jsp"); return viewresolver; } } public class webinitializer implements webapplicationinitializer { public void onstartup(servletcontext container) throws servletexception { annotationconfigwebapplicationcontext ctx = new annotationconfigwebapplicationcontext(); ctx.register(webmvcconfig.class); ctx.setservletcontext(container); servletregistration.dynamic servlet = container.addservlet("dispatcher", new dispatcherservlet(ctx)); servlet.setloadonstartup(1); servlet.addmapping("/"); } } and controller looks like:
@controller public class helloworldcontroller { @autowired private meetingrepository meetingrepository; @requestmapping("/hello") public string helloworld(model model) { model.addattribute("message", "message"); model.addattribute("meeting", meetingrepository.findone(1l)); return "helloworld"; } @requestmapping("/hel") public string hel(model model) { model.addattribute("message", "message"); return "helloworld2"; } }
after commenting meetingrepository field , helloworld() method servlet works fine. if not commented doesn't working:

org.apache.tomcat.util.threads.taskthread$wrappingrunnable.run(taskthread.java:61) java.lang.thread.run(thread.java:745) it looks, spring not making beans when using spring mvc. how should configure application working properly?
edit meetingrepository class:
public interface meetingrepository extends jparepository<meeting, long> { } @configuration @enablejparepositories(basepackages = "com.szymon.repository") @enabletransactionmanagement public class dataaccessconfig { @bean public localentitymanagerfactorybean entitymanagerfactory() { localentitymanagerfactorybean localentitymanagerfactorybean = new localentitymanagerfactorybean(); localentitymanagerfactorybean.setpersistenceunitname("postgres"); return localentitymanagerfactorybean; } @bean public jpatransactionmanager transactionmanager(entitymanagerfactory entitymanagerfactory) { jpatransactionmanager jpatransactionmanager = new jpatransactionmanager(); jpatransactionmanager.setentitymanagerfactory(entitymanagerfactory); return jpatransactionmanager; } } it's working well, because i've tested it:
@runwith(springjunit4classrunner.class) @contextconfiguration(classes = dataaccessconfig.class) public class meetingrepositorytest { @autowired private meetingrepository meetingrepository; @test public void test() { meeting meeting = new meeting(); meeting.setaddeddate(new date()); meeting.setmeetingdate(new date(system.currenttimemillis() + 604800000)); meeting.setnotes("moje pierwsze spotkanie."); meeting.setplace("pokoj 200"); meetingrepository.save(meeting); assert.asserttrue(true); } }
try placing @enabletransactionmanagement , @enablejparepositories(basepackages=...) on webmvcconfig.java class , place @repository on meetingrepository class.
although dataaccessconfig class marked @configuration not being referenced in webinitializer class. webinitializer class referencing webmvcconfig , considered.
if want can specify dataaccessconfig along webmvcconfig using ctx.register(webmvcconfig.class, dataaccessconfig.class);. should work well.
