ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
封装起来:
1 public class ApplicationContextUtil { 2 private static ApplicationContext applicationContext = null; 3 public ApplicationContextUtil(){ 4 //无参构造器,可以不用写 5 } 6 7 static{ 8 applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml"); 9 } 10 11 public ApplicationContext getApplicationContext() { 12 return applicationContext; 13 }
使用时,直接用类名.方法调用即可:ApplicationContextUtil.ApplicationContextUtil();
1 Resource resource = new ClassPathResource("applicationContext.xml"); 2 BeanFactory factory = new XmlBeanFactory(resource);
封装起来:
1 public class ApplicationContextFactoryUtil { 2 private static BeanFactory beanFactory = null; 3 public ApplicationContextFactoryUtil(){ 4 5 } 6 7 static{ 8 Resource resource = new ClassPathResource("applicationContext.xml"); 9 beanFactory = new XmlBeanFactory(resource); 10 } 11 12 public BeanFactory getBeanFactory() { 13 return beanFactory; 14 } 15 }
使用时,直接用类名.方法调用即可:ApplicationContextFactoryUti.getBeanFactory();
