customerconcretefactory.java

说明DAO是如何使用的。带源码说明。

public class CustomerConcreteFactory {

	public static CustomerDAOIntf getCustomerDAOIntf(String className) throws Exception {
		
		Class cls = null;
		
		try {
		
			cls = Thread.currentThread().getContextClassLoader().loadClass(className);
		
		}
		catch(Exception err) {
			
			System.out.println(err);
			
		}
		
		return (CustomerDAOIntf)cls.newInstance();
		
	}
	
}
