What are the pros and cons of using @Autowired in a class that will be wired up by Spring?
I probably just don't understand it, but to me it almost seems like an anti-pattern - your classes start to become aware that they are tied to a DI framework, rather than just being POJOs. Maybe I'm a glutton for punishment, but I like having t...
hi everyone,
i am using spring from scala and i am facing a problem when trying to inject a service with a trait/superclass.
This is my code:

var myService:MyService = null

def setMyService(ms:MyService) = myService = ms
}
@RunWith(classOf[SpringJUnit4ClassRunner])

Hi,
is there a way to use dependency injection to inject all available implementations of a specific interface in spring?
This is kind of the same thing as asked here for .NET.
Though my aim is to use @Autowired for this:
public class Foo{
@Autowired
private IDataCollector[] collectors;
}
Is this supported, would this require h...

Hi,
We're currently adding some new features to an old webapp which was using only JSP without any framework for the front. We have added Spring recently, and we would like to autowire our beans in our modified JSP, while not rewriting everything to use SpringMVC, Struts2 or Tapestry5.
We're using autowiring by type, so it leads to get...
I have an Enum containing three different Status types. These statuses should be displayed in an email sent to users, and the strings containing the statuses to be displayed are stored in messages.properties (read using an implementation of Spring class org.springframework.context.MessageSource). This works well in a normal Spring contro...

I have this Spring config:

The class TheClass implements TheInterface. Then I have this (hypothetical) Java code:

The autowiring of TheInterface works but the autowiring of TheClass fails. Spring gives me a NoSuchBeanDefinitionException fo...

although in my @Webservice class
I extend SpringBeanAutowiringSupport, autowiring simply does not work for Spring 2.5,
tomcat6.
nothing is injected.
I tested those beans autowiring in main method, using classpathcontext, everything is injected fine.
But not for jax-ws endpoint.
do you have ideas?

I am using Java-based Spring configuration in my project, specifying bean construction in @Bean-annotated methods in @Configuration. Recently, Recently, I've started to think that maybe it would've been better to use @Autowired to remove all non-important beans from @Configuration, leaving only small "root" set of them (key services and ...
Is it correct that I can put context:annotation-config in my XML config and it will automatically inject the bean class without needing any annotations?
So instead of using these annotation types:
public class Mailman

private String name;

private Parcel Parcel;
public Mailman(String name)
{
