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);
