java - 将 Hibernate 集成到 Spring 3 项目中

Question

我简单地创建了 Spring 应用程序。我受到 http://outbottle.com/annotated-dependency-injection-inversion-of-control-di-ioc-in-spring-3-web-mvc-using-netbeans/ 的启发。但这个项目只将数据保存到 session 中。我想将 Hibernate 集成到这个应用程序中。旧应用程序，即上面的教程，运行正确，但是当我想修改 hibenrate 和 mysql 的应用程序时，我在启动应用程序时收到错误。我不知道我必须在应用程序中更改什么。我添加了包 cz.ryska.model 并生成了 HibernateUtil 和 Hibernate 映射文件和 POJO。我将 hibernate.reveng.xml 添加到默认包中。此时应用程序运行正确。但是当我更改 DAO 类时，我收到错误(错误在我的问题末尾)。

修改DAO为:

package cz.ryska.dipapp.dao;

import cz.ryska.dipapp.entities.Book;
import java.util.List;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

@Repository
public class BookDao implements BookDaoI{

    @Autowired
    private SessionFactory sessionFactory;

    @SuppressWarnings("unchecked")
    @Override
    public List<Book> list() {
        return this.sessionFactory.getCurrentSession().createQuery("from Book").list();
    }

    @Override
    public void addBook(Book book) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }

    @Override
    public void deleteBook(Integer bookId) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }

    @Override
    public Book get(String id) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }

    @Override
    public Book save(Book book) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }

    @Override
    public void delete(Book book) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }

    @Override
    public Book create(Book book) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }

    @Override
    public void update(Book book) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }

}

我只修改了方法list()，因为欢迎页面没有使用其他方法。

Controller 是:

package cz.ryska.dipapp.controllers;

import cz.ryska.dipapp.entities.Book;
import cz.ryska.dipapp.service.BookService;
import javax.servlet.http.HttpServletRequest;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

/**
 *
 * @author Ondra
 */
@Controller
@RequestMapping("/book")
public class BookController {

    @Autowired
    private BookService bookService;

    @RequestMapping(value="/list", method= RequestMethod.GET)
    public String list(ModelMap map){
        map.put("bookList", bookService.list());
        return "/book/list";
    }
.
.
.
}

服务是:

package cz.ryska.dipapp.service;

import cz.ryska.dipapp.dao.BookDao;
import cz.ryska.dipapp.entities.Book;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

/**
 *
 * @author Ondra
 */
@Service("bookService")
public class BookServiceImpl implements BookService{

    @Autowired
    private BookDao bookDao;

    @Override
    public List<Book> list() {
        return bookDao.list();
    }
.
.
.
    }

Hibernate 配置文件是:

当我使用修改 DAO 类而不是旧的教程 DAO 类时，我收到此错误:

我不知道我犯了什么错，也不知道我忘记了 hibernate 集成项目中的哪些更改。感谢您的提示。

Answer 1

您需要在 spring 配置中添加/启用 Spring 对 Hibernate 的支持(并且需要添加 hibernate jar)

Spring 配置

<bean id="datasource"
   class="com.mchange.v2.c3p0.ComboPooledDataSource">
   <property name="driverClass" value="org.postgresql.Driver" />
   <property name="jdbcUrl"
      value="jdbc:postgresql://localhost:5432/learninghibernate" />
   <property name="user" value="postgres" />
   <property name="password" value="p" />
   <property name="minPoolSize" value="2" />
   <property name="maxPoolSize" value="4" />
</bean>

<bean id="hibernateSessionFactory"
    class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
      <property name="dataSource" ref="datasource" />
      <property name="configLocation">
         <!-- or where your hibernate config file is located-->
         <value>classpath:hibernate.cfg.xml</value>
      </property>
</bean>

hibernate 配置

<hibernate-configuration>
   <session-factory>
      <property name="dialect">
         org.hibernate.dialect.MySQLDialect
      </property>
      <property name="hbm2ddl.auto">none</property>

      <mapping ...

   </session-factory>
</hibernate-configuration>

我建议阅读教程(例如: http://howtodoinjava.com/2013/03/21/spring-3-and-hibernate-integration-tutorial-with-example/ )我建议使用 Hibernate 实现的 JPA (2.0)(使用 EntityManager)，但不要使用旧的 Hiberante Session 样式
