Enable Java EE Annotations, Java 9 onwards

• Java EE or Java, enterprise Edition is not available by default since Java 9.
• To access Java EE we need to include following library in Java 9
• javax.annotation-api
• Since @ Postconstruct and @Predestroy annotation Are parts of Java EE. We need to use following tag in our beans xml To enable all Java EE beans.
• <context:annotation-config />
• However, we may not require to enable all Java EE annotations in some cases Which is also a good programming practice.In such cases To enable only a single bean and it’s corresponding annotation we must declare that class as a bean Explicit in our xml file.
• For example to Enable @postconstruct and @predestroy annotations, we must Declare following bean explicitly
• <bean class="org.springframework.context.annotation.CommonAnnotationBeanPostProcessor"/>
