proxycustomerdaoimpl.java

说明DAO是如何使用的。带源码说明。

import java.io.*;

public class ProxyCustomerDAOImpl implements CustomerDAOIntf {

	public int getCustomerID() throws Exception {
		
		int value = ((CustomerDAOIntf)CustomerConcreteFactory.getCustomerDAOIntf("CustomerDAOImpl")).getCustomerID();
		
		System.out.println("OK, value = " + value);
		
		return value;
		
	}
	
}
