java - @Autowired is not working with beans defined in application context file -

i defined bean in spring context file 'applicationcontext.xml' below :

<bean id="daobean" class="org.mockito.mockito" factory-method="mock">         <constructor-arg value="com.xxx.daoimpl" /> </bean>  

in service class (serviceimpl), using bean below:

 @component("serviceimpl")  public class serviceimpl{         // other code here          @autowired         private transient daoimpl daobean;          // other code here     } 

my service class being accessed junit test class.

@runwith(springjunit4classrunner.class) @contextconfiguration(locations = { "/applicationcontext.xml" })  public class junittest{     // other code here      @autowired     private transient serviceimpl serviceimpl;      // test cases here } 

when execute test case, gives error saying:

error creating bean name 'serviceimpl': injection of autowired dependencies failed; nested exception org.springframework.beans.factory.beancreationexception: not autowire field: private transient com.xxx.daoimpl

when remove @autowired service class , use @resource(name = "daobean") test case works fine.

public class serviceimpl{             // other code here              @resource(name = "daobean")             private transient daoimpl daobean;              // other code here         } 

my question why @autowired not working in case? need configure thing else @autowired, can work properly. don't want change service layer classes replace @autowired @resource.

mockito.mock() has generic return type t erased @ runtime, spring cannot infer type of created mock registered object in spring context. that's why @autowired doesn't work (as tries dependency type).

check out this answer solution problem.
