Hibernate IdentifierGenerationException：无法识别的id类型：uuid-binary

Question

大家好，谢谢你的时间。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;
    }
}

尝试持久化新实例时，我得到以下堆栈跟踪：

我见过许多涉及使用@GenericGenerator的解决方案。如果模型由供应商提供且无法修改，那么我该如何纠正这种情况。我遇到过片段，建议我可以通过SessionFactory注册默认生成器，但我还没有确定如何。

非常感谢任何帮助。

修改

我做了一些挖掘跟踪指示的来源，我在org.hibernate.id.IdentifierGeneratorHelper中找到了这一部分：

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()
        );
    }
}

乍看之下，除非我错过了链中更高层的东西，否则似乎没有办法将原始文件作为生成的id返回。

进一步修改：

数据库中的列类型不正确。修复它并没有解决问题。我注意到，如果我自己使用java.util.UUID.randomUUID生成UUID，Hibernate会正确地保存ID。在这一点上，我正在向应用程序生成的UUID前进，但我想找出为什么我一直遇到这个问题。或者，我愿意接受为什么我不应该让Hibernate生成uuids。

Answer 1

您还可以在package-info.java文件中声明一个生成器，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;

PatientEntity.java：

public class PatientEntity implements Patient {

    @Id
    @GeneratedValue(generator = "UUID")
    @Column
    private UUID id;

Answer 2

所以线索位于您引用的org.hibernate.id.IdentifierGeneratorHelper片段上方几行：

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

在您的情况下，您可以创建实现UserType和ResultSetIdentifierConsumer的自定义ID类型。见see an explanation of template matching from an earlier question
