Regarding Chin Huang's answer above...

Your example won't actually work, or at least isn't working for me locally. That's because you're initializing the SampleService object using @Autowired, but you specify AutowireCapableBeanFactory.AUTOWIRE_NO on the properties. Instead set it to AutowireCapableBeanFactory.AUTOWIRE_BY_TYPE or AutowireCapableBeanFactory.AUTOWIRE_BY_NAME.

Also, this is odd, so I may be doing something wrong. But it seems that with AutowireCapableBeanFactory.AUTOWIRE_BY_TYPE, I have to have a setProp() with @Autowired for it to work. So instead of this:

public class Main {
    @Autowired
    private SampleService sampleService;

    public static void main(String[] args) {
        Main main = new Main();
        ApplicationContextLoader loader = new ApplicationContextLoader();
        loader.load(main, "applicationContext.xml");
        main.sampleService.getHelloWorld();
    } 
}

I have to do this:

public class Main {
    private SampleService sampleService;

    public static void main(String[] args) {
        Main main = new Main();
        ApplicationContextLoader loader = new ApplicationContextLoader();
        loader.load(main, "applicationContext.xml");
        main.sampleService.getHelloWorld();
    } 

    @Autowired
    public void setSampleService(SampleService sampleService) {
        this.sampleService = sampleService;
    }
}

If I have, as in Chin's original example, private data with @Autowired, the DI fails. I'm using 3.1.1.RELEASE and I think some of the auto-wiring stuff has changed in 3.1.x, so it may be due to that. But I'm curious as to why this wouldn't work, since that's consistent with earlier releases of Spring.
