Java代码

1. //@Test//xml
2. public void AutoWireTestXML() {
3. ApplicationContext context = new ClassPathXmlApplicationContext("testAutoWire.xml");
4. People people = (People) context.getBean("people");
5. IdCard idCard = people.getIdCard();
6. // autowire="byName" 当people bean上没有加这个标签时，打印值为null，加后则打印出了对象
7. System.out.println(idCard);
8. }

	//@Test//xml
	public void AutoWireTestXML() {
		ApplicationContext context =  new ClassPathXmlApplicationContext("testAutoWire.xml");
		People people = (People) context.getBean("people");
		IdCard idCard = people.getIdCard();
		// autowire="byName" 当people bean上没有加这个标签时，打印值为null，加后则打印出了对象
		System.out.println(idCard);
