hibernate 自定义类型（地址）

自定义类型和动态组件都是在一张数据表（customer）里面操作的。

Customer.java:

//自定义值类型
	public AddressType1 getSaddress() {
	   return this.sAddress;
     }

    public void setSaddress(AddressType1 a) {
	   this.sAddress = a;
    }

Customer.hbm.xml:

<!--
  	 自定义类型，关于地址
  	-->
  	<property name="saddress"  type="basicCar.bean.AddressType1">
  	<column name="province"/>	
 	<column name="city"/>	
 	<column name="street"/>

  	</property>

 

Test.java:

void saveEntity() {

		//Customer ss = new Customer(300,"小白","北京");
		Customer ss = (Customer) session.load(Customer.class, new Long(300));
		ss.setSaddress(address);
		
		session.save(ss);
}

//测试自定义类型
