Caros bom dia,

sou novo no spring e estou tentando criar um projeto para a faculdade usando o eclipselink e spring.
Porém estou com algumas dificuldades para encontrar material na internet, também o meu inglês não ajuda muito.
Acredito que meu erro esta no aplicationcontext, não tenho certeza que ele esta achando o meu persistence.xml e ta dando erro naquele datasource,
bom se vcs puderem dar uma olhada, obrigado.

Meu erro.

Acho que o problema está na classe do seu datasource e quando você liga o datasource no entityManagerfactory.

Tente fazer o seguinte

Modifique o bean entityManagerFactory, a propriedade datasource para ref=“datasource”, afinal o nome bean do datasource é datasource.

<property name="dataSource" ref="DataSource" />

E no bean do datasource tente colocar essa class

Também não entendi esse bean

Se você está usando o eclipseLink como provider, porque definir o hibernate como jpa vendor ?

darklordkamui 11 de jan. de 2013

a sua classe ‘livroAction’ não esta no contexto do spring…
vc anotou ela com @Component ou @Service ou @Repository?

posta ela porfavor =D

lele_vader 11 de jan. de 2013

O erro é dessa classe datasource que ele colocou como class do bean datasource, pois tem que ser o caminho completo da classe.

darklordkamui 11 de jan. de 2013

é verdade, agora que vi, ele colocou o class como dataSource… sendo que tem que por o caminho completo da classe do spring…

é por isso que é tenso sair copiando e colando projetos da internet… o rsg tinha que ter desenvolvido passo a passo…

acredito que tenha mais coisas a ser feita, alem de alterar o datasource;… hehehhehe

Caros bom dia,

estive alguns dias fora e não consegui dar continuidade. Bom fiz o que os amigos falaram e passou dessa parte, porem
apareceu um novo erro. Request null, mas a unica coisa que eu mudei foi a integração com o spring,
se eu tirar as configurações do spring, deixando somente o struts2+ jpa ele funciona corretamente.
Alguém pode me ajudar?

mostre a sua classe LivroBO, dentro do pacote business.

rsg 22 de jan. de 2013

Bom dia lele_vader.
Obrigado pela atenção.

Segue, o que eu reparei é que o @autowired livroBO dentro meu livroAction esta vindo null…Não sei se pode ser isso, bom segue a classe.

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;


@Service
@Transactional
public class LivroBO extends BaseBO{
	
	//private LivroDAO livroDAO = new LivroDAO();
	@Autowired
	private LivroDAO livroDAO;
	
	public boolean salvarLivroBO(Livro livro){
		return livroDAO.salvar(livro);
	}
	
	public boolean editarLivroBO(Livro livro){
		return livroDAO.editar(livro);
	}
	
	public boolean excluirLivroBO(Livro livro){
		return livroDAO.remover(livro);
	}
	
	public List<Livro> listarLivrosBO(Class<?> classe){
		return livroDAO.listarTodos(Livro.class);
	}
	
	public Livro listarPorIdBO(Class<?> classe, Integer id){
		return livroDAO.listarPorID(Livro.class, id);
	}

	public LivroDAO getLivroDAO() {
		return livroDAO;
	}

	public void setLivroDAO(LivroDAO livroDAO) {
		this.livroDAO = livroDAO;
	}

}

Classe BO:

public abstract class BaseBO implements BaseBOInterface {

}

E BOInterface:

public interface BaseBOInterface {

}

lele_vader 22 de jan. de 2013

deve ser isso que está causando o erro mesmo.
Me mostra o seu livroAction.

Tenta criar um get para o livroBO na action

rsg 23 de jan. de 2013

É eu estava lendo http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/beans.html#beans-autowired-annotation
e ele menciona setters e dai percebi que estava faltando get/set na Action e BO, e acabei gerando ambos mas nada mudou.

lele_vader 23 de jan. de 2013

Mesmo com o get e set na action ainda o service continua como null ?

rsg 23 de jan. de 2013

@Autowired
	private LivroBO livroBO;
	
	public LivroBO getLivroBO() {
		return livroBO;
	}
	
	public void setLivroBO(LivroBO livroBO) {
		this.livroBO = livroBO;
	}

Você configurou o seu web.xml para usar com o spring ?

rsg 23 de jan. de 2013

Sim, pesquisei os erros mais comuns nesses casos e eram não anotar

<context:component-scan base-package="br.com.knowtec" />

no applicationContext e tbm o web.xml.

Acho que falta da propriedade contextConfigLocation, apontando para o arquivo do appContext.

rsg 23 de jan. de 2013

Agora a tarde vou dar uma pesquisada nisso, mas seria alguma coisa nesse sentido?

<context-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/applicationContext.xml </param-value> </context-param>

Obrigado!!

lele_vader 23 de jan. de 2013

Isso ai, considerando que o nome do seu arquivo é applicationContext.xml

rsg 23 de jan. de 2013

Pois eh, testei do jeito que esta ali e outros semelhantes e não foi, não sei mais pra onde correr…

rsg 24 de jan. de 2013

Pesquisei bastante, mas ainda não consegui.

Alguémmmm, uma luz no fim do túnel plsssssss. hahaha. :lol:
