求助:一对一外键与主键双向关联问题，谢谢大家

[65426]

在论坛曾有人发过相同的问题，他没有把解决问题的方法贴出来：http://community.csdn.net/Expert/topic/4441/4441578.xml?temp=.163067

我也有一个双向关联的一对一的问题，我的运行环境:JDK1.4.0,oracle9i,TOMCAT5.5,Hibernate3.1.be
由于代码太长，我中间删除了一点
LMCustomer.java:
public class LMCustomer implements Serializable {

private static final long serialVersionUID = 1L;

/** identifier field */
private Integer customerId;

/** persistent field */
private String name;

/** nullable persistent field */
private com.rfcyber.licensemanager.domain.LMGeneral lmGeneral;
}
LMCustomer.hbm.xml:
<class

<param name="sequence">lm_customer_seq</param>
</generator>

测试：
public void testsaveLmCustomer(){

try{
customer.setName("stephen lei");
customer.setAddress1("sz city1");
customer.setAddress2("sz city2");
customer.setEmail("[e-mail]");
customer.setCdSerialNo("pac0001");

//option general
general.setName("sabrina wang");
general.setIssuerDate(new Date());
general.setStartDate(new Date());
general.setProductType("A");
general.setMac("MAC");

general.setLmCustomer(customer);

customer.setLmGeneral(general);
customerDAO.saveLMCustomer(customer);

}catch(Exception ex){
ex.printStackTrace();
}

}
=========================================================================================
问题:现在插入时只能插入一张表：LM_CUMSTOMER,而LM_GENERAL 表不能插入，后台打印是：
Hibernate: select lm_customer_seq.nextval from dual
Hibernate: insert into LM_CUSTOMER (NAME, CD_SERIAL_NO, EMAIL, ADDRESS1, ADDRESS2, CITY, STATE, ZIPCODE, CUSTOMER_ID) values (?, ?, ?, ?, ?, ?, ?, ?, ?)
怎么才能两张表同时插入？谢谢各位大侠帮忙!!!

各位大哥，大姐，怎么没人拔刀相助呢?

[yingtju]

LMCustomer.hbm.xml:
<one-to-one cascade="all" ...>

下面的General的映射也没定义cascade
考虑一下都写上把

问题解决了，把constrained="true"去掉就行。，谢谢yingtju(蚂蚁)
