Spring DuplicateKeyException

Question

yerine JpaSystemException'ı attı DataAccessException işleminde sorun yaşıyorum.

Benzersiz bir anahtar kısıtlaması ihlal edildiğinde, bir JmarSystemException var ve bir DuplicateKeyException değil!

Bu sorun hakkında konuşulan bir konu buldum, ancak hiç kimse sorunu çözmek için bana yardımcı olmuyor. Bir beton org.springframework.dao istisnasını nasıl eşleyebilirim?

Benim persistence.xml dosya şöyle görünüm:

Ve MySQL işlem yöneticisi hakkında yapılandırmaları: O alakalı değildir bence çünkü SQLServer hakkında yapılandırmayı ihmal ettik

. Bu db ile ilgili çeviri hatasıyla ilgilenmiyorum. Yakalamak

Ben MySQL sorgu günlük kaydı etkin ettik ve ben aşağıdaki sorguyu var: Ben Eğer

insert into ubi (code, version) values ('A', 0) 

Sorguyu mysql konsolundan çalıştırmayı denedim: ERROR 1062 (23000): Duplicate entry 'A' for key 'code'

sql-error-codes.xml ürün kodunedeniyle hatalı yapılandırılmış özelliklerine

<property name="duplicateKeyCodes"> 
    <value>1062</value> 
</property> 

yüzden bazı İstisna çeviri sorunu olduğunu düşünüyorum .. ama hangi: spring-jdbc-3.0.6.RELEASE.jar 10 i hata kodu 1062 db mysql için bu şekilde yapılandırıldığını bulundu?

Spring 3.0.6.RELEASE ve Hazırda 3.6.9.FINAL kullanıyorum

herhangi cevap için teşekkür ederiz! Marco

Answer 1

Bu sorun, Spring veya veritabanı sürücünüzle ilgili değil. Bir süre önce kendim çalışmak zorunda kaldım. Hibernate'i bir JPA sağlayıcısı olarak kullanmanıza olanak tanıyan hibernate-entitymanager kavanozu içinde bazı kötü istisna çevirisinin bulunduğunu fark ettim.AbstractEntityManagerImpl.convert() yöntemi, HibernateException s öğelerinin JPA PersistenceException s'ye dönüştürülmesinden sorumludur, ancak hiçbir "yinelenen anahtar" veya "benzersiz kısıtlama" istisnasıyla ilgilenmez. latest code on Github bile bunu düzeltmiş gibi görünmüyor. Buna bir bakacak olursanız, convert() yönteminin uzun bir ifs zinciri vardır, ancak bunların hiçbiri bu özel durum türünü kapsamaz, bu nedenle aşağıya doğru düşer ve genel bir PersistenceException'a çevrilir. Oldukça sinir bozucu.

Answer 2

EntityManager ürününüzün üzerinde bir vendorAdapter olduğundan emin olun. Bu, jpa sağlayıcınızın gelişmiş hata kodları sağlamasına olanak tanır.

Answer 3

Bu kümeyi yapılandırmamda yaptım.

transactionManager.setJpaDialect(new HibernateJpaDialect());
