Spring getBean with type validation
Not really but there is a runtime workaround that at least removes the need for an @SuppressWarnings. You can make your class abstract and let Spring instrument your code:
public abstract class Test { Set<String> getMyBean();}and then inject a lookup method in your XML config:
<bean class="Test"> <lookup-method name="myBean" bean="myBean" /></bean>It's not really statically checked but it fails-fast at runtime and you keep the ugly casting out of your code.
maybe this can be usefull to you:
Set<String> setBean= null;Map<String, Set> beans = applicationContext.getBeansOfType(Set.class);for (Map.Entry<String, Set> bean: beans.entrySet()) { ParameterizedType thisType = (ParameterizedType) bean.getClass().getGenericSuperclass(); Class<?> parametrizedClass= thisType.getActualTypeArguments()[0]; if (parametrizedClass.isAssignableFrom(String)) { setBean= (Set<String>) bean; }}
