一对一保存失败

Question

登陆用户信息:
users.hbm.xml
[code="xml"]
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

    <property name="username" type="java.lang.String">
        <column name="username" length="20" />
    </property>
    <property name="password" type="java.lang.String">
        <column name="password" length="20" />
    </property>
    <property name="sort" type="java.lang.String">
        <column name="sort" length="10" />
    </property>

</class>

[/code]

用户详细信息:
userinfos.hbm.xml
[code="xml"]<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

users





























[/code]

他们是一对一的关系

测试类:
public class Test {

/**
 * @param args
 */
public static void main(String[] args) {
    // TODO Auto-generated method stub
    Users u=new Users();
    Userinfos userinfos=new Userinfos();
    ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
    u.setUsername("hisen");
    u.setPassword("123456");
    u.setSort("用户");
    userinfos.setCardno("333");
    userinfos.setUsers(u);
    u.setUserinfos(userinfos);


    IUserDao userDao=(IUserDao)ctx.getBean("userDao");
    userDao.saveUser(u);


}

保存的时候出现错误:

不知道哪里配置错了

Answer 1

sessionFactory

估计你的spring接管hibernate的地方配置不对吧
