Проблемы с КДИ - (Weld + TomCat7 + JSF) - Отличная библиотека

Я начинаю проект с CDI с помощью сварки, и я получаю следующее сообщение об ошибке при попытке введения:Проблемы с КДИ - (Weld + TomCat7 + JSF)

Ваша первая проблема заключается в том, что класс UserRepositoryImpl не имеет конструктора по умолчанию (пустой), а также есть метод @Produces, поэтому нет возможности его создать. Удалить EntityManager entityManager от конструкторов от Repository и UserRepositoryImpl классов.
Изменить конструктор в Repository для:

protected Repository() { 

    /// this.entityManager = entityManager; // <= this is already injected by 
              // @Inject protected final EntityManager entityManager; 
    @SuppressWarnings("unchecked") 
    Class<T> clazz = (Class<T>) ((ParameterizedType) getClass().getGenericSuperclass()).getActualTypeArguments()[0]; 
    this.clazz = clazz; 
}

Ваша вторая проблема будет неправильной инъекции PersistenceContext. Вы либо должны использовать EJB (впрыснуть EntityManager через @PersistenceContext) или веб-модули используют:

@PersistenceUnit(unitName="default") 
EntityManagerFactory emf; 
... 
EntityManager em = emf.createEntityManager();

И ваша третья проблема будет транзакции - снова вам необходимо либо переключиться на EJB, или обрабатывать транзакции в то время как сохраняющиеся ваши бобы ,

Я рекомендую сначала прочитать следующее перед кодированием:

@Gas Спасибо вам за отзывы и ссылки, теперь работает, я не знаю, если это лучший способ:

UserRepositoryImpl

package br.com.repositories; 

import javax.inject.Inject; 
import javax.persistence.EntityManager; 
import javax.transaction.Transactional; 
import br.com.models.User; 

@Transactional 
public class UserRepositoryImpl extends Repository<User, Long >implements UserRepository { 


    @Inject 
    protected UserRepositoryImpl(EntityManager entityManager) { 
     super(entityManager); 
    } 


}

Repository

package br.com.repositories; 

import java.io.Serializable; 
import java.lang.reflect.ParameterizedType; 
import java.util.List; 
import javax.persistence.EntityManager; 
import javax.persistence.TypedQuery; 

public abstract class Repository<T, I extends Serializable> { 

    protected final EntityManager entityManager; 
    protected final Class<T> clazz; 

    protected Repository(EntityManager entityManager) { 
     this.entityManager = entityManager; 
     @SuppressWarnings("unchecked") 
     Class<T> clazz = (Class<T>) ((ParameterizedType) getClass().getGenericSuperclass()).getActualTypeArguments()[0]; 
     this.clazz = clazz; 
    } 

    public void refresh(T entity){ 
     entityManager.refresh(entity); 
    } 

    public void create(T entity) { 
     entityManager.persist(entity); 
    } 

    public T update(T entity) { 
     return entityManager.merge(entity); 
    } 

    public void destroy(T entity) { 
     entityManager.remove(entity); 
    } 

    public T find(I id) { 
     return entityManager.find(clazz, id); 
    } 

    public List<T> findAll() { 
     TypedQuery<T> query = entityManager.createQuery("FROM " + clazz.getName() ,clazz);  
     return query.getResultList(); 
    } 

}

EntityManagerProducer

package br.com.util; 

import javax.enterprise.context.ApplicationScoped; 
import javax.enterprise.context.RequestScoped; 
import javax.enterprise.inject.Disposes; 
import javax.enterprise.inject.Produces;

public class EntityManagerProducer { 

    private EntityManagerFactory factory; 

    public EntityManagerProducer() { 
     factory = Persistence.createEntityManagerFactory("default"); 
    } 

    @Produces @RequestScoped 
    public EntityManager createEntityManager() { 
     return factory.createEntityManager(); 
    } 

    public void closeEntityManager(@Disposes EntityManager manager) { 
     manager.close(); 
    } 

}

UserController

package br.com.vw.controllers; 

import javax.annotation.PostConstruct; 
import javax.enterprise.context.RequestScoped; 
import javax.inject.Inject; 
import javax.inject.Named; 

import br.com.models.User; 
import br.com.repositories.UserRepository; 



@Named("userController") 
@RequestScoped 
public class UserController { 

    @Inject UserRepository userRepository; 

    UserController(){ 

    } 

    @PostConstruct 
    public void init(){ 
     System.out.println("Inicialilizado o construtor"); 
    } 

    public String getMessage(){ 
     return "Conteúdo da mensagem"; 
    } 

    public void create(){ 

     System.out.println("Método create disparado"); 

     User user = new User(); 
      user.setEmail("[email protected]"); 
      user.setName("Marcos de Freitas"); 

     userRepository.create(user); 


    } 

}
