@Autowired - No qualifying bean of type found for dependency
You should autowire interface AbstractManager instead of class MailManager. If you have different implemetations of AbstractManager you can write @Component("mailService") and then @Autowired @Qualifier("mailService") combination to autowire specific class.
This is due to the fact that Spring creates and uses proxy objects based on the interfaces.
I had this happen because my tests were not in the same package as my components. (I had renamed my component package, but not my test package.) And I was using @ComponentScan in my test @Configuration class, so my tests weren't finding the components on which they relied.
So, double check that if you get this error.
The thing is that both the application context and the web application context are registered in the WebApplicationContext during server startup. When you run the test you must explicitly tell which contexts to load.
Try this:
@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations = {"classpath:/beans.xml", "/mvc-dispatcher-servlet.xml"})
