[英]Java Spring Hibernate Schema-Validation: Missing Table
[英]Hibernate acessing table in schema other than dbo results with Schema-validation: missing table
我有一個具有兩種模式的數據源: dbo和example 。
我已經在dbo模式中創建了一個名為A的表,並將其映射到休眠狀態:
@Entity
@Table(name = "A")
public class ATable {
private Integer id;
@Id
@Column(name = "id")
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
}
它運行時沒有出現預期的錯誤,然后我使用以下語句將表移動到示例架構(成功運行):
alter schema example transfer dbo.A
並更改了休眠類:
@Entity
@Table(name = "A", schema = "example")
public class ATable {
private Integer id;
@Id
@Column(name = "id")
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
}
但是在運行它時,它將引發以下異常,並退出程序。
INFO: HHH000262: Table not found: A
Exception in thread "main" org.hibernate.tool.schema.spi.SchemaManagementException: Schema-validation: missing table [A]

我還嘗試使用以下表注釋代替:
@Table(name = "example.A")
但這引發了一些相同的異常:
INFO: HHH000262: Table not found: example.A
Sep 22, 2017 3:53:36 PM org.hibernate.tool.schema.extract.internal.InformationExtractorJdbcDatabaseMetaDataImpl processGetTableResults

看來我需要以某種方式配置休眠以支持額外的架構,但不了解如何。
應用:
public class Application {
private static SessionFactory sessionFactory;
public static void main(String[] args) {
Configuration configuration = new Configuration().configure();
sessionFactory = configuration.buildSessionFactory();
sessionFactory.openSession().close();
}
}
還有hibernate.cfg.xml
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!--MSSQL-->
<property name="hibernate.connection.url">jdbc:jtds:sqlserver://localhost:1433/d1</property>
<property name="connection.driver_class">net.sourceforge.jtds.jdbc.Driver</property>
<property name="hibernate.connection.username">a</property>
<property name="hibernate.connection.password">1</property>
<property name="dialect">org.hibernate.dialect.SQLServerDialect</property>
<!--Global-->
<property name="hibernate.connection.pool_size">10</property>
<property name="show_sql">true</property>
<property name="hibernate.hbm2ddl.auto">validate</property>
<property name="hibernate.current_session_context_class">thread</property>
<mapping class="com.a.A" />
</session-factory>
</hibernate-configuration>
原來,從hibernate.cfg.xml中刪除以下行可以解決問題
<property name="hibernate.hbm2ddl.auto">validate</property>
