Hibernate工具：外键必须与引用的主键具有相同的列数

我正在尝试实现Hibernate工具（逆向工程）。这是工具生成的.hbm.xml。

这是我正在尝试应用查询（HQL）的代码：

public void getDetails() {

    try {

        Session session = sessionFactory.openSession();

        Transaction transaction = session.beginTransaction();

        String hql = "select c.msisdn, c.password FROM CrbtSubscriberMaster c where rownum<20";
        Query query = session.createQuery(hql);
        List<Object[]> itr = query.list();
        // System.out.println("[" + itr+ "]");
        session.getTransaction().commit();
        for (Object[] object : itr) {
            // CrbtSubMasterDemo pojo = (CrbtSubMasterDemo) iterator.next();
            System.out.println("["
                    + String.format("mobile:%s, password:%s", object[0],
                            object[1]) + "]");

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

}

这就是Excetion Stack：

我是Hibernate的新手请帮助我理解并解决问题。提前致谢。

更新：CRBT_SUBSCRIBER_MASTER的DB描述 

Name                       Null?    Type
----------------------------------------- ---------
MSISDN                   NOT NULL VARCHAR2(15)
STATUS                   NOT NULL VARCHAR2(3)
DATE_REGISTERED           NOT NULL DATE
PLAN_INDICATOR           NOT NULL NUMBER(3)
RBT_CODE                 NOT NULL NUMBER(10)
PASSWORD                 NOT NULL VARCHAR2(15)
TPIN                      NOT NULL VARCHAR2(4)
FREE_EVENTS_USED          NOT NULL NUMBER(2)
BLACK_LISTED              NOT NULL NUMBER(1)
LANGUAGE                  NOT NULL NUMBER(1)
DEFAULT_GROUP_SETTING     NOT NULL RAW(30)
DEFAULT_SINGLE_SETTING    NOT NULL RAW(30)
DATE_SETTING_VALIDITY     NOT NULL NUMBER(1)
IMSI                      NOT NULL VARCHAR2(20)
LAST_CHARGED                       DATE
IS_MONTHLY_CHARGEABLE              VARCHAR2(1)
CORP_ID                   NOT NULL NUMBER(5)

还有更多的colums。 根据我的知识，MSISDN是主键，但该工具似乎将Corp Id作为主键。

更新2：工具本身创建的Pojo类

2 个答案:

答案 0 :(得分：0)

该工具很可能有错误或缺少功能。它没有生成正确的数组索引列。

<index></index>

应该是这样的：

<index column="idx"></index>

索引是存储数组的表的主要kay的一部分。需要在数组中存储顺序。

答案 1 :(得分：0)

好吧，伙计们。这是我使用Eclipse Luna帮助下载的Hibernate工具中的一个错误。而Bug的错误名称是表名映射。即。

<class name="com.telemune.bean.CrbtSubscriberMaster" table="CRBTSUBSCRIBERMASTER">

其中表的真实名称是CRBT_SUBSCRIBER_MASTER。即映射应为：

<class name="com.telemune.bean.CrbtSubscriberMaster" table="CRBT_SUBSCRIBER_MASTER">

我刚尝试过，它解决了我的问题。如果有人有解释为什么会这样？请解释。 更新： 我在这里注意到的另一个重要事项是选择图像中显示的选项 使用Java 5语法 可能会有所帮助。
