尝试使用UUID作为我的ID为PostgreSQL和H2，目前的例外是H2休眠的UUID UUID类型

这里是我的实体

@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; 
} 
}

我不知道，如果它是相关的，但我使用Spring Data Rest Repository来坚持这一点。

我想能够坚持，最终，在PostgreSQL的原生类型，不管它是H2需要UUID是（我是相当新的H2）。

你可以张贴堆栈跟踪的休息吗？ – 2014-09-02 05:55:57

@ThomasMueller增加了 – xenoterracide 2014-09-02 23:31:15

一个简单的'@Id @GeneratedValue private java.util.UUID id;' 在H上的Hibernate 5+中工作参见[documentation]（http://docs.jboss.org/hibernate/orm/ 5.0/userguide/html_single/Hibernate_User_Guide.html＃标识符）。可能也适用于其他数据库。 – 2016-06-10 09:07:13

更新：与休眠5 I was able to get more cross database compatible UUID's included（注意：我不是实现者，但我确实给它一个刺）。

@Entity 
public class MyEntity { 
    @Id 
    @GeneratedValue 
    @Column(columnDefinition = "uuid", updatable = false) 
    public UUID getId() { 
     return id; 
    } 
}

原始

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（至少要等到休眠实现类似）

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;

在实体

终于

@Id 
@Override 
@GeneratedValue(generator = "uuid2") 
@GenericGenerator(name = "uuid2", strategy = "uuid2") 
@Column(name = "id", columnDefinition = "uuid") 
public UUID getId() { 
    return id; 
}
