The registerShutdownHook in spring

If you are using Spring IoC in non web application and want to gracefully downdown all resources we use registerShutdownHook(). This method calls the relevant destroy methods. In order to register a shutdown hook, you have to call the the registerShutdownHook() method which found in the AbstractApplicationContext class.

AppMain.java

package com.roseindia.common;

import org.springframework.context.support.AbstractApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class AppMain {
	public static void main(String[] args) {
		AbstractApplicationContext context = new ClassPathXmlApplicationContext(
				new String[] { "context.xml" });
		System.out.println("Add a shutdown hook for the above context");
		context.registerShutdownHook();
	}
}

context.xml


<beans xmlns="http://www.springframework.org/schema/beans"

  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  xsi:schemaLocation="http://www.springframework.org/schema/beans
