在javaConfig中使用@Qualifier + @Bean（autowire = Autowire.BY_TYPE）

Question

I have an Employee bean having Address type of dependency. I'm trying to configure autowiring in javaConfig. But getting NoQualifyingBeanException .
Although I'm using @Qualifier() annotation as follow :

@Configuration
public class MyConfig {

    @Bean(name="addr1")
    public Address address() {      
        return new Address("Hello","hi",112233);
    }

    @Bean(name="address")
    public Address addressAgain() {
        return new Address("See You","Bi",114422);
    }

    @Bean(name="emp",autowire=Autowire.BY_TYPE)
    @Qualifier("addr1")
    public Employee employee() {

        Employee e = new Employee();
        e.setName("Raghu");
        e.setEmpID(111);
        //e.setAddress(address());

        return e;
    }

}

Answer 1

Specifying a different name attribute in each @Bean method is not enough.
You should consider marking one of the beans as @Primary :

@Primary
@Bean(name = "address")
public Address addressAgain() {
    return new Address("See You");
}

And leave the other(s) without :

@Bean(name="addr1")
public Address address() {      
    return new Address("Hello","hi", 112233);
}

Note that you don't need to add the @Qualifier("addr1") annotation in the employee() method to be able to autowire the addr1 bean.
Spring already knows the Address bean instance you refer to as you set the dependency from a @Bean method : address() .

So it is enough :

@Bean(name = "emp", autowire = Autowire.BY_TYPE)
public Employee employee() {
    Employee e = new Employee();
    e.setName("Raghu");
    e.setAddress(address());
    return e;
}
