我是Hibernate中的新手,在尝试将Friend_Job对象保存到数据库时出现异常。休眠: - 无法执行JDBC批量更新
我从数据库中获取Friend和Job对象并创建新的Frien_Job对象。
Test.java
SessionFactory sessionFectory = new Configuration().configure().buildSessionFactory();
Session session = sessionFectory.openSession();
Transaction transaction = session.beginTransaction();
Friend friend= (Friend) session.load(Friend.class, new Integer(1));
Job job = (Job) session.load(Job.class, new Integer(3));
Friend_Job friend_Job = new Friend_Job();
friend_Job.setFriend(friend);
friend_Job.setJob(job);
friend_Job.setCompanyName(job.getCompanyName());
session.save(friend_Job);
transaction.commit(); //Exception here
Friend_Job.hbm.xml
<hibernate-mapping>
<class name="hibernateTest.Friend_Job" table="FRIEND_JOB">
<id name="primaryKey" column="PRIMARY_KEY">
<generator class="increment"/>
</id>
<property name="companyName" type="string" column="COMPANY_NAME"/>
<property name="salary" column="SALARY"/>
<many-to-one name="friend" class="hibernateTest.Friend" cascade="none" column="FK_FRIEND_ID"/>
<many-to-one name="job" class="hibernateTest.Job" cascade="none" column="FK_JOB_ID"/>
</class>
</hibernate-mapping>
例外: -

所致:java.sql.BatchUpdateException:ORA-00932:不一致数据类型:预计BINARY获得NUMBER
Friend_Job.java
public class Friend_Job {
private int primaryKey;
private String companyName;
private int salary = 0;
private Friend friend;
private Job job;
否则是设置者和获取者。
请让我知道是否需要更多信息.... 在此先感谢。
其列的表'FRIEND_JOB'是二进制类型的空值 我克服产生的? – Firo 2012-02-24 08:48:40
@Firo: - 没有任何列类型的二进制文件,我不知道为什么这个异常抛出。 – 2012-02-29 04:42:42
