Spring创建IOC容器的方式解析
1、直接得到IOC容器对象
ApplicationContextapplicationContext=newClassPathXmlApplicationContext("applicationContext.xml");
封装起来:
publicclassApplicationContextUtil{ privatestaticApplicationContextapplicationContext=null; publicApplicationContextUtil(){ //无参构造器,可以不用写 } static{ applicationContext=newClassPathXmlApplicationContext("applicationContext.xml"); } publicApplicationContextgetApplicationContext(){ returnapplicationContext; }
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
Resourceresource=newClassPathResource("applicationContext.xml"); BeanFactoryfactory=newXmlBeanFactory(resource);
封装起来:
publicclassApplicationContextFactoryUtil{ privatestaticBeanFactorybeanFactory=null; publicApplicationContextFactoryUtil(){ } static{ Resourceresource=newClassPathResource("applicationContext.xml"); beanFactory=newXmlBeanFactory(resource); } publicBeanFactorygetBeanFactory(){ returnbeanFactory; } }
使用时,直接用类名.方法调用即可:ApplicationContextFactoryUti.getBeanFactory();
