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();
