Welcome to the website of Davis Fiore

It's possible to intercept creation and distruction of a bean by implementing two interfaces:

	public class Employee implements InitializingBean, DisposableBean {

		@Override
		public void destroy() throws Exception {
			// Something goes here
		}

		@Override
		public void afterPropertiesSet() throws Exception {
			// Something goes here
		}
	}

However to intercept the distruction, you also need to set an hook by calling registerShutdownHook() after the creation of the application context:

	AbstractApplicationContext ctx = new ClassPathXmlApplicationContext("spring.xml");
	ctx.registerShutdownHook();
	Employee employee = (Employee)ctx.getBean("employee");

There is also a way to set the callbacks in your xml configuration:

	<bean id="employee" class="org.davis.Employee" init-method="doCreationOps" destroy-method="doDistructionOps">
	</bean>

You can also add the two methods to all the beans in that way:

	<beans default-init-method="doCreationOps" default-destroy-method="doDistructionOps">
