Here an Example

public class MyFancyBean implements ApplicationContextAware {

  private ApplicationContext applicationContext;

  void setApplicationContext(ApplicationContext applicationContext) {
    this.applicationContext = applicationContext;
  }

  public void businessMethod() {
    //use applicationContext somehow
  }

}

However you rarely need to access ApplicationContext directly. Typically you start it once and let beans populate themselves automatically.

Here you go:

ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");

Note that you don't have to mention files already included in applicationContext.xml. Now you can simply fetch one bean by name or type:

ctx.getBean("someName")

Note that there are tons of ways to start Spring - using ContextLoaderListener, @Configuration class, etc.
