Ao habilitar a anotação @Cache começa a dar uma exception atrás da outra.

Ao habilitar @Version o banco de dados esta criando novos registros toda hora ao atualizar um registro.

Oi Matheus,

Sobre o Cache: Qual é a exceção que dá? Onde vc está usando @Cache (entity ou collection)?

Sobre @Version: aqui também preciso de mais detalhe para ajudar.

Estou usando em Entity:

@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)

E sobre o version apenas adicionei o atributo no meu model

@Version
private Integer versao;

E criei o campo como integer no banco e adicionei no formulario:

<input name="versao" type="hidden" value="${obj.versao}">

Oi Matheus, tudo bem?

Veja se você setou a propriedade hibernate.cache.region.factory_class no seu persistence.xml.

Quanto ao @Version verifique se o valor da versão chega no input. O seu problema geralmente acontece quando inserimos uma entidade sem mandar a versão.

Abraços!

Fala ai Leonardo, quanto ao hibernate eu setei sim:

<property name="hibernate.cache.use_second_level_cache" value="org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory"/>

E quanto ao @Version o valor esta chegando na input sim.

Oi Matheus,

Sobre @Version: Tente isolar o probema. Crie um teste para ver o @Version funcionando sem o Vraptor. Assim a gente pode verificar se o problema realmente está relacionado com Hibernate ou não.

Sobre o cache, repare que na exceção aparece uma outra chave:

`hibernate.cache.region.factory_class``

Ok, vou testar o @Version separado.

Sobre o cache não entendi.

Esta faltando anotação no persistence.xml ?

solução!

Fala Matheus, vamos lá!

A propriedade hibernate.cache.use_second_level_cache indica se queremos ativar o cache de segundo nível ou não. Nesse caso, ela vai receber o valor true ou false, ok?

O valor que você colocou ("org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory"), na verdade, é o nome da classe do provider do cache. Esse valor tem que ser setado na propriedade hibernate.cache.region.factory_class.

Ou seja:

<property name="hibernate.cache.use_second_level_cache" value="true"/>

Tudo bem?

Abraços!

Leonardo, show de bola, o cache esta funcionando.

Desculpe pela desatenção, lendo o PDF com mais calma agora pude ver que no código java estava com a property correta, porém o código em persistence esta errado, depois da uma arrumada la.

Abraços, valeu.
