@Autowired - No qualifying bean of type found for dependency

Question

I\'ve started my project by creating entities, services and JUnit tests for services using Spring and Hibernate. All of this works great. Then I\'ve added spring-mvc to make

Answer 1

Can you try annotating only your concrete implementation with @Component? Maybe the following answer could help. It is kind of a similar problem. I usually put Spring annotations in the implementation classes.

Answer 2

My guess is that here

<context:component-scan base-package="pl.com.radzikowski.webmail" use-default-filters="false">
    <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
</context:component-scan>

all annotations are first disabled by use-default-filters="false" and then only @Controller annotation enabled. Thus, your @Component annotation is not enabled.

Answer 3

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.

Answer 4

I was facing the same issue while auto-wiring the class from one of my jar file. I fixed the issue by using @Lazy annotation:

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Lazy;

    @Autowired
    @Lazy
    private IGalaxyCommand iGalaxyCommand;

Answer 5

Correct way shall be to autowire AbstractManager, as Max suggested, but this should work fine as well.

@Autowired
@Qualifier(value="mailService")
public MailManager mailManager;

and

@Component("mailService")
@Transactional
public class MailManager extends AbstractManager {
}

Answer 6

The solution that worked for me was to add all the relevant classes to the @ContextConfiguration annotation for the testing class.

The class to test, MyClass.java, had two autowired components: AutowireA and AutowireB. Here is my fix.

@ContextConfiguration(classes = {MyClass.class, AutowireA.class, AutowireB.class})
public class MyClassTest {
...
}
