Utility bean for getting Spring beans from static context.

ApplicationContextHolder.java

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

@Component
public class ApplicationContextHolder implements ApplicationContextAware {

    private static ApplicationContext applicationContext;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        synchronized (this) {
            if (ApplicationContextHolder.applicationContext == null) {
                ApplicationContextHolder.applicationContext = applicationContext;
            }
        }
    }

    public static <T> T getBean(Class<T> clazz) {
        return applicationContext.getBean(clazz);
    }

    public static <T> T getBean(String qualifier, Class<T> clazz) {
        return applicationContext.getBean(qualifier, clazz);
    }

}

This gist save my day! Thank you so much.

It's a good solution, the only problem is that sonar indicates an error because the static field is wrote from a instance method.

thanks

Thanks!
