How to get spring application context object reference?


This page gives an example to get spring application context object with in non spring managed classes as well. It is not possible to have all classes as spring managed classes, in such classes you need to get spring application context object. This can be achieved by using ApplicationContextAware interface. Here are the steps to achieve application context object:

Create a new class and implement ApplicationContextAware method and its unimplemented method as shown below:

package com.java2novice.spring;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

public class ApplicationContextProvider implements ApplicationContextAware{

	private static ApplicationContext context;
	
	public ApplicationContext getApplicationContext() {
        return context;
    }
	
	@Override
	public void setApplicationContext(ApplicationContext ac)
			throws BeansException {
		context = ac;
	}
}

Declate above bean in your applicationContext.xml file as shown below:

<bean id="applicationContextProvder" 
						class="com.java2novice.spring.ApplicationContextProvider"/>

And finally here is the code to access application context and getting bean reference:

ApplicationContextProvider appContext = new ApplicationContextProvider();
TestBean tb = appContext.getApplicationContext().getBean("testBean", TestBean.class);

Exception Vs Error
An error is an irrecoverable condition occurring at runtime like out of memory error. These kind of jvm errors cannot be handled at runtime. Exceptions are because of condition failures, which can be handled easily at runtime.
Famous Quotations
Millions long for immortality who do not know what to do with themselves on a rainy Sunday afternoon.
