Question

我在为Hibernate，Spring，Oracle数据库（本地创建）配置测试环境时遇到了一些问题。所有bean通常在启动时初始化，除了＆＃34; sessionFactory＆＃34;。这个例外让我感到困惑：

Caused by: org.hibernate.AnnotationException: Cannot find the expected secondary table: no MY_INFORMATION available for net.me.business.model.MyInformation

这是休眠/弹簧配置：

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"
p:dataSource-ref="dataSource" p:packagesToScan="net.me.business.model" p:hibernateProperties-ref="hibernateProperties" />

<util:properties id="hibernateProperties">
  <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
  <prop key="hibernate.show_sql">true</prop>
   <!--<prop key="hibernate.connection.url">jdbc:h2:mem:test;INIT=create schema if not exists myschema\;SET SCHEMA myschema\;MODE=Oracle;DB_CLOSE_DELAY=-1</prop>--> 
  <!--<prop key="hibernate.hbm2ddl.auto">update</prop>-->
</util:properties>

我不知道我在哪里错过了什么。

这是github repo。请看一下：

README.md中有一些注释

问题＃2

有没有办法动态地将相同的序列映射作为ID生成器添加到每个表中？无需在每个班级编写注释。序列名称模板将是[tablename] _SEQ。

Answer 1

我已经弄明白我在哪里做错了。这两个人不在一起：

@Table(name="ADDRESS")
public  class Address implements Serializable {


    @Column(name="MODIFIED_BY",table="ADDRESS",length=100)
    @Basic
    private String modifiedBy;


}

在课程开始时

@Table(name="ADDRESS")，在每个字段上@Column(...table="ADDRESS"...)。此映射由JPA Modeler netbeans插件生成。我不会再依赖它了：）

上面的

问题＃2 仍然可供讨论。

谢谢大家。

Answer 2

目前，JPA Modeler正在开发中。因此，请使用JPA Modeler xml的附件提出您的错误here。谢谢你的贡献！
