Spring boot＆＃39; sessionFactory＆＃39;或者＆＃39; hibernateTemplate＆＃39;是必须的

标签： java spring hibernate spring-boot

我使用Spring Boot创建了一个Web服务，其中有一个商店列表，包括他们的客户和他们的卡。很容易也许。

我使用hibernate 4连接到本地MySQL数据库。

问题是我收到了这个错误（问题中已经提到过）：

代码分为以下包：控制器，dao，模型和服务。类非常相似，所以我只发布其中一个。

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;
    }
}

我真的不明白我错过了什么，我的pom看起来很好，因为我添加了Spring boot JPA 的的pom.xml

那我应该如何实例化sessionFactory或hibernateTemplate？我试图自动装配它们，但这是不可能的。

1 个答案:

答案 0 :(得分：1)

如果您要使用Spring Data JPA（正如您的pom.xml所建议的那样），使用过时的HibernateTemplate是没有意义的。

使用Spring Data JPA时，Spring Boot不会创建SessionFactory bean，但会创建EntityManagerFactory。 您可以自动装配它并打开SessionFactory。

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

您也可以将Session绑定到org.springframework.orm.hibernate4.SpringSessionContext。

但是，Spring Data JPA存储库使用的是不同的上下文。

我无法创建一个Spring项目，其中HibernateTemplate和Spring Data JPA存储库共享Session上下文。
