Hibernate disidentifierGenerationException:未识别的ID类型:UUID二进制



大家好，感谢您的时间。我在自动生成java.util.uuids时遇到了一些麻烦。

考虑以下实体：

@javax.persistence.Entity
@javax.persistence.Table(name="clients")
public class Client {
    @javax.persistence.GeneratedValue
    @javax.persistence.Id
    private UUID id;
    public UUID getId() {
        return id;
    }
}

尝试坚持新实例时，我会得到以下stacktrace：

javax.persistence.PersistenceException: org.hibernate.id.IdentifierGenerationException: unrecognized id type : uuid-binary -> java.util.UUID

我已经看到了许多涉及@GenericGenerator使用的解决方案。如果该模型是由供应商提供的，并且无法修改，那么我如何纠正情况。我遇到了片段，这表明我可以通过SessionFactory注册默认的生成器，但是我还没有确定如何。

。

任何帮助都非常感谢。

编辑：

我在痕迹指示的源中进行了一些挖掘，然后我在org.hibernate.id.idefiergeneratorhelater中来到了此部分：

Class clazz = type.getReturnedClass();
if (rs.getMetaData().getColumnCount() == 1) {
    if ( clazz == Long.class ) {
        return rs.getLong( 1 );
    }
    else if ( clazz == Integer.class ) {
        return rs.getInt( 1 );
    }
    else if ( clazz == Short.class ) {
        return rs.getShort( 1 );
    }
    else if ( clazz == String.class ) {
        return rs.getString( 1 );
    }
    else if ( clazz == BigInteger.class ) {
        return rs.getBigDecimal( 1 ).setScale( 0, BigDecimal.ROUND_UNNECESSARY ).toBigInteger();
    }
    else if ( clazz == BigDecimal.class ) {
        return rs.getBigDecimal( 1 ).setScale( 0, BigDecimal.ROUND_UNNECESSARY );
    }
    else {
        throw new IdentifierGenerationException(
            "unrecognized id type : " + type.getName() + " -> " + clazz.getName()
        );
    }
}

一目了然，除非我缺少链中的更高的东西，否则似乎除了原始ID以外没有其他任何东西。

进一步编辑：

数据库中的列类型不正确。修复它没有纠正问题。但是，我确实注意到，如果我使用java.util.uuid.randomuuid生成UUID，那么Hibernate会正确地将ID持续存在。在这一点上，我正在使用应用程序生成的UUID前进，但是我想找出为什么我一直在遇到这个问题。另外，我愿意娱乐为什么我不应该让冬眠产生UUID的原因。

您也可以在package-info.java文件中声明生成器，然后通过ID字段上的@GeneratedValue注释使用它。

package-info.java：

@org.hibernate.annotations.GenericGenerator(
        name = "UUID",
        strategy = "org.hibernate.id.UUIDGenerator"
)
package org.leanhis.patientmanagement;

病人java：

public class PatientEntity implements Patient {
    @Id
    @GeneratedValue(generator = "UUID")
    @Column
    private UUID id;

所以线索在org.hibernate.id.idefierGeneratorHelper snippet上方有几行：

if ( ResultSetIdentifierConsumer.class.isInstance( type ) ) {
        return ( ( ResultSetIdentifierConsumer ) type ).consumeIdentifier( rs );
    }

在您的情况下，您可以创建一种实现USERTYPE和RESSERSETSIDENFIERCONSUMER的自定义ID类型。请参阅此教程
