利用Hibernate的逆向工程生成：
?
?Customer.java
?
?
OrderAction.java
?
测试test.java
package com.hibernate.annotation.test;public class Test {public static void main(String args[]) {Customer customer = new Customer();customer.setName("baidu6");CustomerAction ca = new CustomerAction();/** * * 添加对象 * */ca.addCustomer(customer);OrderAction oa = new OrderAction();Order order = new Order();order.setOrdernumber("6zz");order.setCustomer(customer);oa.addorder(order);}}?
