First, the IoC Container context should be generated via the corresponding configuration:
For XML configuration based bean -- context = new ClassPathXmlApplicationContext("app-config.xml");
For Java configuration based bean -- context = new AnnotationConfigApplicationContext(BeanConfig.class);
For annotation based bean -- context = new FileSystemXmlApplicationContext("/path/app-config.xml");
Secondly, retrieve bean from the IoC Container via the context
Name_XML_Bean bean = context.getBean(Name_XML_Bean.class);

The life cycle (from instantiation to garbage collection) of Spring beans are controller by Spring IoC Container, but those beans are always standby and ready for use. There are two way to use Spring beans:
External Use -- Retrieve from the IoC Container by application
Internal Use -- Fulfill the dependency need for another bean from the IoC container.
