这是我的实体
@Entity
@Table(name = "tasks")
public class Task
private static final Logger log = LoggerFactory.getLogger(Task.class);
@Id
@NotNull
@GeneratedValue(generator="system-uuid")
@GenericGenerator(name="system-uuid", strategy = "uuid")
@Column(name = "task_id", columnDefinition = "uuid")
private UUID id;
@NotNull
@NotEmpty
@Size(min = 1, max = 120)
private String description;
public String getDescription ()
return description;
public void setDescription (final String description)
this.description = description;
public UUID getId ()
return id;
public void setId ( final UUID uuid )
id = uuid;
我不确定它是否相关，但我正在使用 Spring Data Rest Repository 来保存它。
我希望最终能够作为 PostgreSQL 中的本机类型持续存在，并且无论 H2 是什么都需要 UUID（我对 H2 相当陌生）。
【问题讨论】：
一个简单的@Id @GeneratedValue private java.util.UUID id; 在 H 上的 Hibernate 5+ 中工作。请参阅 documentation。可能也适用于其他数据库。
@NatanCox 很有趣，在让他们制作功能后，我从未更新过这个答案
@NatanCox 更新了我的答案，包括我为pgjdbc bug 写的文字
【参考方案1】：
更新： 使用 Hibernate 5 I was able to get more cross database compatible UUID's included（注意：我不是实施者，尽管我确实尝试过）。
@Entity
public class MyEntity
@Id
@GeneratedValue
@Column( columnDefinition = "uuid", updatable = false )
public UUID getId()
return id;
原创
Dzone posted an article about a second version of the UUID generator last year
首先创建自己的用户类型（至少在 hibernate 实现类似之前）
public class UUIDType extends AbstractSingleColumnStandardBasicType<UUID>
public static final String NAME = "uuid-name";
public static final UUIDType INSTANCE = new UUIDType();
public UUIDType()
super( UUIDSqlTypeDescriptor.INSTANCE, UUIDTypeDescriptor.INSTANCE );
public String getName()
return NAME;
public static class UUIDSqlTypeDescriptor implements SqlTypeDescriptor
public static final UUIDSqlTypeDescriptor INSTANCE = new UUIDSqlTypeDescriptor();
public int getSqlType()
// ugh
return Types.VARCHAR;
@Override
public boolean canBeRemapped()
return true;
public <X> ValueBinder<X> getBinder( final JavaTypeDescriptor<X> javaTypeDescriptor )
return new BasicBinder<X>( javaTypeDescriptor, this )
@Override
protected void doBind( PreparedStatement st, X value, int index, WrapperOptions options )
throws SQLException
st.setObject( index, javaTypeDescriptor.unwrap( value, UUID.class, options ) );
;
public <X> ValueExtractor<X> getExtractor( final JavaTypeDescriptor<X> javaTypeDescriptor )
return new BasicExtractor<X>( javaTypeDescriptor, this )
@Override
protected X doExtract( ResultSet rs, String name, WrapperOptions options ) throws SQLException
return javaTypeDescriptor.wrap( rs.getObject( name ), options );
@Override
protected X doExtract( CallableStatement statement, int index, WrapperOptions options )
throws SQLException
return javaTypeDescriptor.wrap( statement.getObject( index ), options );
@Override
protected X doExtract( CallableStatement statement, String name, WrapperOptions options )
throws SQLException
return javaTypeDescriptor.wrap( statement.getObject( name ), options );
;
然后注释你的模型package-info.java
@TypeDef(
name = UUIDType.NAME,
defaultForType = UUID.class,
typeClass = UUIDType.class
)
package com.xenoterracide.rpf.model;
import org.hibernate.annotations.TypeDef;
import org.hibernate.type.UUIDType;
import java.util.UUID;
终于在你的实体中
@Id
@Override
@GeneratedValue(generator = "uuid2")
@GenericGenerator(name = "uuid2", strategy = "uuid2")
@Column(name = "id", columnDefinition = "uuid")
public UUID getId()
return id;
【讨论】：
以上是关于休眠 UUID 为 UUID 类型的主要内容，如果未能解决你的问题，请参考以下文章
tomcat restart => 找不到 SessionFactory [uuid=...,name=null]
Pyspark 可为空的 uuid 类型 uuid 但表达式的类型为字符变化
如何修复“UUID 类型的方法参数缺少 URI 模板变量 'uuid'”？
