无法使用Hibernate将实体保存到数据库中

无法使用Hibernate将实体保存到数据库中

问题描述：

我使用Spring 3.3.4与Hibernate 5.1.3，使用java 1.7和Sql Server数据库。我写了一个简单的类映射到表，但无法保存。我得到一个异常，我的ID为空。我预计它会自动生成但是失败。从例外我可以看到，它期望找到一个序列。但在以前的Hibernate版本中，使用本地生成器可以实现相同的功能，而无需使用序列。它应该仍然有可能。下面是我的配置，代码和异常：无法使用Hibernate将实体保存到数据库中

配置文件：

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans"

</beans>

我相关的代码片段：

@Entity(name = "Task") 
@Table(name = "task") 
public class TaskImpl extends SubmittedTaskImpl implements Task { 

    private static final long serialVersionUID = -1711538547188780401L; 
    @Id 
    @GeneratedValue 
    @Column(name = "id") 
    private long taskId;

最后我的例外：

答

14：33：10,373错误[org.hibernate.id.enhanced.TableStructure]（http-127.0.0.1-8080-3）无法读取hi值： java.sql.SQLException：无效的对象名'hibernate_sequence' 。

的原因是代替IdentityGenerator虽然我们使用的是正确 MSSQLServerDialect的 SequenceStyleGenerator被使用，它返回supportsIdentityColumns（）=真。 的SequenceStyleGenerator试图找到“hibernate_sequence” 表不改变代码存在 解决方法为MSSQL：

@Id 
@GeneratedValue(strategy=GenerationType.IDENTITY) 
public long getId() 
{ 
    return id; 
}

入住这里 reported issue

+0

更感谢这个错误。在链接之后，我关闭了属性“hibernate.id.new_generator_mappings”（将其设置为“false”）。然后它的工作原理不会将其更改为GenerationType.IDENTITY。另外，我改变的是在我的SQL Server中，我改变了以下列方式创建列： 旧： CREATE TABLE [dbo]。[bot_task]（ \t [id] [numeric]（19，0） NOT NULL， ... 新： CREATE TABLE [DBO] [bot_task（ \t [ID] [数字]（19,0）IDENTITY（1,1）NOT NULL， ... –

+1

也。切换到GenerationType.IDENTITY也可以工作（无需关闭属性“hibernate.id.new_generator_mappings”） –
