4.測試類

public class Test {
	public static void main(String[] args) {
		
		String xmlPath="/spring/src/com/heima/spring/代理半自動/applicationContext.xml";
		ApplicationContext applicationContext = new ClassPahtXmlApplicationContext(xmlPath);
		
		AccountService accountService =(AccountService)applicationContext.getBean("proxyAccountService");
		accountService.transfer("zhangsan", "lisi", 200);
		
		
		
		
	}
