autowiring ServiceListFactoryBean

[paul.mckenzie]

Hi

I have a ServiceListFactoryBean which creates a list of service implementations:

<bean id="services"
      class="org.springframework.beans...ServiceListFactoryBean"
      p:serviceType="ServiceInterface"/>

I can access the services using the applicationContext without a problem:

final List services = ctx.getBean("services", List.class));

I can also use trad constructor-arg injection successfully:

<bean id="aClass" class="AClass">
    <constructor-arg ref="services"/>
</bean>

But if I try to autowire the dependency

@Autowired @Qualifier("services") private List services;

Then I get a BeanCreationException caused by

FatalBeanException: No element type declared for collection [java.util.List]

I am using Spring 3.0.

Try using generics to indicate what type exactly you want injected into your list:

@Autowired @Qualifier("services") private List<ServiceInterface> services;

I tried that and I got

Caused by: org.springframework.beans.factory.NoSuchBeanDefini tionException: No matching bean of type [...ServiceInterface] found for dependency [collection of ...ServiceInterface]: expected at least 1 bean which qualifies as autowire candidate for this dependency.
