1、直接得到 IOC 容器对象

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

封装起来：

public class ApplicationContextUtil { private static ApplicationContext applicationContext = null; public ApplicationContextUtil(){ //无参构造器，可以不用写 } static{ applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml"); } public ApplicationContext getApplicationContext() { return applicationContext; }

使用时，直接用类名.方法调用即可：ApplicationContextUtil.ApplicationContextUtil();

2、通过工厂类得到 IOC 容器创建的对象

Resource resource = new ClassPathResource("applicationContext.xml"); BeanFactory factory = new XmlBeanFactory(resource);

封装起来：

public class ApplicationContextFactoryUtil { private static BeanFactory beanFactory = null; public ApplicationContextFactoryUtil(){ } static{ Resource resource = new ClassPathResource("applicationContext.xml"); beanFactory = new XmlBeanFactory(resource); } public BeanFactory getBeanFactory() { return beanFactory; }}

使用时，直接用类名.方法调用即可：ApplicationContextFactoryUti.getBeanFactory();
