Usage

From source file:org.os890.ds.addon.spring.impl.CdiAwareBeanFactoryPostProcessor.java

private BeanDefinition createSpringBeanDefinition(Bean<?> cdiBean) throws Exception {

    if (beanType instanceof Class) { //to support producers
        beanDefinition.setBeanClass((Class) beanType);
    } else { //fallback since spring doesn't support multiple types
        beanDefinition.setBeanClass(cdiBean.getBeanClass());
