Spring Boot'sessionFactory'或'hibernateTemplate'是必需的

我使用Spring Boot創建一個Web服務，其中我有一個店鋪列表與他們的costumers和他們的卡。很容易也許。Spring Boot'sessionFactory'或'hibernateTemplate'是必需的

我使用hibernate 4連接到本地MySQL數據庫。

的問題是，我得到這個錯誤（這個問題已經提到）：控制器，DAO模式和服務：

的代碼中是包分配。類非常相似，所以我只會發布其中的一個。

CardController：

package net.mitro.controller; 

import net.mitro.service.interfaces.CardService; 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestMethod; 
import org.springframework.web.bind.annotation.RestController; 

import java.util.List; 

/** 
* Created by mitro on 15/03/2017. 
*/ 
@RestController 
@RequestMapping("/cards") 
public class CardController { 

    @Autowired 
    private CardService cardService; 

    @RequestMapping(method = RequestMethod.GET) 
    public List getAllShops(){ 
     return cardService.getAllCards(); 
    } 
}

CardServiceImpl：

package net.mitro.service; 

import net.mitro.dao.interfaces.CardDao; 
import net.mitro.service.interfaces.CardService; 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.stereotype.Service; 

import java.util.List; 

/** 
* Created by mitro on 15/03/2017. 
*/ 
@Service 
public class CardServiceImpl implements CardService{ 

    @Autowired 
    private CardDao cardDao; 

    @Override 
    public List getAllCards(){ 
     return this.cardDao.getAllCards(); 
    } 
}

CardDaoImpl：

package net.mitro.dao; 

import net.mitro.dao.interfaces.CardDao; 
import net.mitro.model.Card; 
import org.springframework.dao.support.DataAccessUtils; 
import org.springframework.orm.hibernate4.support.HibernateDaoSupport; 
import org.springframework.stereotype.Repository; 

import javax.transaction.Transactional; 
import java.util.List; 

/** 
* Created by mitro on 15/03/2017. 
*/ 
@Repository("cardDao") 
public class CardDaoImpl extends HibernateDaoSupport implements CardDao{ 

    @Override 
    @Transactional 
    public List getAllCards() { 
     return getHibernateTemplate().find("from card"); 
    } 

    @Override 
    @Transactional 
    public int cardCount() { 
     return DataAccessUtils.intResult(getHibernateTemplate().find("select count(*) from card")); 
    } 

    @Override 
    @Transactional 
    public void delete(int id) { 
     getHibernateTemplate().delete(this.findById(id)); 
    } 

    @Override 
    @Transactional 
    public Card findById(int id) { 
     return (Card) getHibernateTemplate().get(Card.class, id); 
    } 

    @Override 
    @Transactional 
    public void insert(Card card) { 
     getHibernateTemplate().save(card); 
    } 

    @Override 
    @Transactional 
    public void update(Card card) { 
     getHibernateTemplate().saveOrUpdate(card); 
    } 
}

卡：

package net.mitro.model; 

import javax.persistence.*; 

/** 
* Created by mitro on 15/03/2017. 
*/ 

@Entity 
@Table(name = "card") 
public class Card { 

    @Id 
    @GeneratedValue(strategy= GenerationType.AUTO) 
    @Column(name = "id_card") 
    private int idCard; 
    @Column(name = "stamps_num_card") 
    private int stampsNumCard; 
    @ManyToOne 
    @JoinColumn(name = "shop") 
    private Shop shop; 
    @ManyToOne 
    @JoinColumn(name = "user") 
    private User user; 

    public Card(){} 

    public void setStampsNumCard(int stampsNumCard) { 
     this.stampsNumCard = ++stampsNumCard; 
    } 

    public int getIdCard() { 
     return idCard; 
    } 

    public int getStampsNumCard() { 
     return stampsNumCard; 
    } 

    public void setShop(Shop shop) { 
     this.shop = shop; 
    } 

    public void setUser(User user) { 
     this.user = user; 
    } 

    public Shop getShop() { 
     return shop; 
    } 

    public User getUser() { 
     return user; 
    } 
}

SO我應該如何實例化這個sessionFactory或hibernateTemplate？我試圖自動裝載它們，但這是不可能的。

幫你一個忙，並使用標準的JPA API而不是舊的，專有的Hibernate API。在使用它的時候，使用spring-data-jpa，它很容易集成到spring-boot中，並且會爲你生成你的DAO。 –

那麼使用JPA比Hibernate更好？ – Mitro

JPA只是一個規範，定義了一個標準的API。 Hibernate是這個規範的實現之一。您可以使用Hibernate，但您應該通過標準的JPA API而不是通過舊的專有Hibernate API來使用它。就像你不使用內部的Tomcat API來開發web應用程序一樣。您使用標準的servlet API。 –

如果您打算使用Spring Data JPA（因爲您的pom.xml會提示），使用廢棄的HibernateTemplate沒有意義。

當Spring Data JPA正在使用時，Spring Boot不會創建SessionFactory bean，但它會創建EntityManagerFactory。您可以自動裝入並解包到SessionFactory。你

@Bean 
public SessionFactory sessionFactory(EntityManagerFactory entityManagerFactory) { 
    return entityManagerFactory.unwrap(SessionFactory.class); 
}

也可結合Session到org.springframework.orm.hibernate4.SpringSessionContext。

但是，Spring Data JPA存儲庫使用不同的上下文。

我無法創建一個Spring項目，其中HibernateTemplate和Spring Data JPA存儲庫共享Session上下文。

Spring Boot'sessionFactory'或'hibernateTemplate'是必需的
