getBeansOfType() function not working?

[James]

Has anyone used XDAT.getContextService().getBeansOfType(MyBean.class) in XNAT 1.7?

I'm Autowiring a bean within a plugin class and trying to access that bean inside the XNAT application. 

Some Example code below.

I'm able to get a beanA by name and by type, but getting ALL beans of type MyBean does not work.

// Plugin Code //

@Component("beanA")

public class BeanA implements myBean{

  // some stuff

}

@Autowired

MyBean beanA;

// XNAT Application code //

public interface MyBean{

  // some stuff 

}

// This doesn't work, returns an empty Map.

XDAT.getContextService().getBeansOfType(MyBean.class);

// This works fine

XDAT.getContextService().getBean("beanA");

// This also works fine

XDAT.getContextService().getBean(MyBean.class);

It looks like the issue is that the application context that’s getting set for the context service is not the full application context? I’m not sure what’s going on there. That service has always been a bit hinky and is, in the bluntest terms, a complete and total hack to give non-Spring code access to objects in the Spring context. I’ll try to play with it some later and see if I can figure out what’s going on with it.

I am also not sure what is going on, but I wanted to chime in to say that I encountered a similar issue. I was trying to do XDAT.getContextService().getBeansOfType(OrmStrategy.class) to get a list of OrmStrategies for managing PACS. I was able to work around it well enough for what I was working on at the time, but I will want to have getBeansOfType working before I release a more general purpose DICOM query/retrieve plugin I am developing.

Thanks for letting us know that this is an issue others are having as well. Hopefully this is something that is easy for us to fix!

I looked into this a bit, and I learned that the difference between getBean and getBeansOfType is that the former also include beans in ancestor factories. The solution is to use BeanFactoryUtils’s beansOfTypeIncludingAncestors instead of getBeansOfType. I added this method to the ContextService (https://bitbucket.org/radiologics_kate/framework/commits/5ac7b961a9badb1c5b08e9e55733ef6d46959cb8), but I don't have permission to submit a PR.

We already have a (slightly different) fix for this bug in the code that will go out with our next release.
