Another approach is to declare this class in web.xml or we can also use ServletContext's addListener method. As standard, we declare a Spring dispatcher servlet that handles all URLs coming to the application, and a Spring Web Context Loader Listener to loads Spring security configuration (in a Spring security configuration file named spring-security.xml file under /WEB-INF folder). The message listener container allows us to register MessageListeners without EJB container. Alternatively, Spring's org.springframework.web.filter.RequestContextFilterand Spring's org.springframework.web.servlet.DispatcherServlet also expose the same request context to the current thread.

For example, if spring-webmvc is on the classpath, this annotation flags the application as a web application and activates key behaviors, such as setting up a DispatcherServlet. can we do with ServletContextExample.java. To activate the entity listener, we have to add the @EntityListeners annotation to our entity post, as follow (or include the various callbacks within our entity, when the operations are simple): @Entity @EntityListeners(PostListener.class) @Data public class Post { ..} Test ServletContextListener allows you to initialise your application when it is deployed. In the example code written here we will demonstrate with an example of an ItemReadListener that is triggered when an item is read and an ItemWriteListener that is invoked when an item is written out.
