ManytoMany com Spring não fecha sessão

Bom dia, sou iniciante em programação e estou com um problema queando utilizo hibernate Annotations e Spring. Tento persistir uma classe no postgresq e ele dáum erro dizendo que há mais de um objeto com o mesmo id, mas já depurei no eclipse e vi que os objetos são diferentes, percebi que se eu utilizar o método .merge na minha classe DAO ele funciona, persiste o objeto, desde que eu já tenha um objeto no BD mas dá pau quando insiro um novo objeto, o erro me diz que o spring não está fechando a sessão e ele pode estar reconhecendo o objeto como outro objeto diferente em vez de ser o mesmo, alguém pode me ajudar a resolver isso?

Quando você está inserindo, o objeto está indo com ID? Ou sem ID?

NNAJ 14 de dez. de 2011

o objeto é pego do banco de dados são feitas as operações necessárias e ele é novamente persistido, ele está com ID, isso já foi conferido

Hebert_Coelho 14 de dez. de 2011

Vc não pode persistir um objeto que já tenha id.

NNAJ 14 de dez. de 2011

mas ele é um update de um objeto que já estava no banco, com o spring pego ele, atualizo os dados e depois tento persistí-lo no banco com as atualizações novamente

NNAJ 14 de dez. de 2011

é um sistema legado que utiliza um tipo especifico de dado, então
na vdd pego ele do bd de um tipo, faço a conversão para outro tipo da minha classe de negócio, trabalho os dados com o objeto do sistema e depois reconverto para o tipo do bd e persisto, mas no objeto da persistência são setados todos os dados que estavam no objeto do sistema para que ele possa fazer o update no bd, mas dá essa mensagem de erro, a conversão ocorre perfeitamente, só a persistência dá esse pau

Hebert_Coelho 14 de dez. de 2011

Na hora de fazer update. Como você está fazendo?

NNAJ 14 de dez. de 2011

é um dao genérico chamo o objeto.salvar(objeto objeto)

public T salvar(T entity) {  
 	   try {  
		   this.getHibernateTemplate().flush();
 		   this.getHibernateTemplate().clear();
 		   this.getHibernateTemplate().saveOrUpdate(entity)  ;
 		   return entity;  
 	   } catch (final HibernateException ex) {  
 	       throw convertHibernateAccessException(ex);  
 	   }  
	 }

Hebert_Coelho 14 de dez. de 2011

Muda isso aqui para depois do save

this.getHibernateTemplate().flush(); this.getHibernateTemplate().clear();
Pq vc ta chamando isso antes do save?

NNAJ 14 de dez. de 2011

para limpar a sessão e atualizar os dados só da sessão atual

NNAJ 14 de dez. de 2011

mudei,só que dá o mesmo erro

NNAJ 14 de dez. de 2011

o DAO genérico

public abstract class DAO <T> extends HibernateDaoSupport
{
	
	private Class<T> persistentClass;  
	 	
	public void setPersistentClass(Class<T> persistentClass) {
		this.persistentClass = persistentClass;
	}

	public Class<T> getPersistentClass() {  
		return this.persistentClass;  
	}
	
	 public T salvar(T entity) {  
 	   try {  
 		   this.getHibernateTemplate().saveOrUpdate(entity)  ;
 		   this.getHibernateTemplate().getSessionFactory().close();
		   this.getHibernateTemplate().flush();
 		   this.getHibernateTemplate().clear();

 		   return entity;  
 	   } catch (final HibernateException ex) {  
 	       throw convertHibernateAccessException(ex);  
 	   }  
	 }

	 public T modify(T entity) {  
	 	   try {  
	 		   this.getHibernateTemplate().flush();
	 		   this.getHibernateTemplate().update(entity)  ;
	 	       
	 	       return entity;  
	 	   } catch (final HibernateException ex) {  
	 	       throw convertHibernateAccessException(ex);  
	 	   }  
	 }
	 
	public void delete(T entity) {  
	   try { 
		   this.getHibernateTemplate().flush();
		   this.getHibernateTemplate().delete(entity);
	   } catch (final HibernateException ex) {  
	       throw convertHibernateAccessException(ex);  
	   }  
	}

se pego o objeto e depois tento salvá-lo mudando do @Cascade.ALL para @Cascade.MERGE, funciona, mas daí a inserção para de funcionar

Hebert_Coelho 14 de dez. de 2011

Da erro que pq vc esta mandando fechar antes de dar o flush

this.getHibernateTemplate().getSessionFactory().close(); this.getHibernateTemplate().flush(); this.getHibernateTemplate().clear();

NNAJ 14 de dez. de 2011

alterei para

public T salvar(T entity) {  
 	   try {  
 		   this.getHibernateTemplate().saveOrUpdate(entity)  ;
		   this.getHibernateTemplate().flush();
 		   this.getHibernateTemplate().getSessionFactory().close();
 		   this.getHibernateTemplate().clear();

 		   return entity;  
 	   } catch (final HibernateException ex) {  
 	       throw convertHibernateAccessException(ex);  
 	   }  
	 }

e o erro é o mesmo, tô gerenciando as sessões com o spring, será que é alguma configuração dele que dá pau?Pq num relação manyToOne e OneToMany deu certo, mas ManyToMany deu erro

Hebert_Coelho 14 de dez. de 2011

Mano. sem ofensas… Leia um livro sobre JPA ou Spring ou Transações ou coisas assim…

this.getHibernateTemplate().getSessionFactory().close(); Isso aqui tem sempre que ser o utlimo comando a ser utilizado quando trata uma transação na unha.

Para que você ta chamando esse dois?

this.getHibernateTemplate().flush();

this.getHibernateTemplate().clear();

Vc sabe para que funciona?

Não estou te zuando, ou diminuindo. É pq tem tando comando aí…

NNAJ 14 de dez. de 2011

olha, eu disse que era iniciante e coloquei os comandos à medida em que pesquisei na net, esse erro não tem a ver com os comandos .flush() e .clear() pq inicialmente a classe salvar estava sem eles e o erro é o mesmo

public T salvar(T entity) {  
 	   try {
 		   this.getHibernateTemplate().saveOrUpdate(entity)  ;

 		   return entity;  
 	   } catch (final HibernateException ex) {  
 	       throw convertHibernateAccessException(ex);  
 	   }  
	 }

com a classe de persistência assim o erro é esse:

pelo que eu vi e pesquisei o erro pode ser provocado pelas anotações do hibernate, mas daí não sei como alterar para que funcione, pq se vc vir minha classes as anotações deveriam funcionar

Pelo fato de ser iniciante que eu sugeri o livro.

Vc estava tendo problemas com a transação.

Vou deixar alguem que entenda mais de Spring para te ajudar.

Eu tenho um pouco de conhecimento em JPA apenas.

Vc não pode persistir um objeto que já tenha id.

Pode sim,basta que o atributo referente ao ID não esteja marcado com @GeneratedValue

Me expressei mal, persistir = método persist do entityManager.

Mas é disso msm q eu to falando

Se o seu @ID estiver marcado com @GeneratedValue e vc passar o objeto pro persist(),vai receber um:“Detached entity passed to persist”,mas sem @GeneratedValue o JPA aceita de boa.
