f the first context initialization didn't use ApplicationContextHelper, then you can't use it either.
The application context is being initialized somewhere else - this depends on how you are starting the application in the first place. You cannot start it twice and if the first context initialization didn't use ApplicationContextHelper, then you can't use it either.
Create a bean that is ApplicationContextAware and use that to push the context (not a specific bean) onto a static member. You can then retrieve it statically from the constraint implementation at runtime.
public class MyApplicationContextHelper implements ApplicationContextAware { private static ApplicationContext applicationContext; public void setApplicationContext(ApplicationContext arg0) throws BeansException { applicationContext = arg0; } public static ApplicationContext getApplicationContext() { return applicationContext; } public static Object getBean(String beanName) { if(beanName==null||beanName.trim().length()==0) { return null; } else{ return applicationContext.getBean(beanName); } } }
