Question

i have a problem with spring 3 tests using junit 4.10 and mybatis. I'm not able to autowire service in the test class.
Here the exception i get

What's wrong? Am i loosing some configurations?
thanks in advance

Answer 1

solved ... the problem was i was trying to autowired a concrete bean without an interface
thanks all for replies :-)
andrea

Answer 2

Change the autowired code from
#Autowired
private MailReceiverAccountService mailReceiverAccountService;
to
#Autowired
private DaoService mailReceiverAccountService;
If you have multiple DaoService implementation classes, use #Qualifier with #Autowired to distinguish them.

Answer 3

In the context xml, you are not providing the base package for scanning the annotated components. Hence you service class is not scanned and autowired. Please add this entry into the context
<context:annotation-config />
<context:component-scan base-package="basepackage" />
