我目前正在一起使用 Spring (3.1.0) 和 Hibernate (4.2.0.Final) 进行项目，加载应用程序时出现此错误。我认为这是一个 Maven 问题，但我看不到哪一个。我在不同的主题上看到了类似的问题，但空指针异常不是我的情况。

这是我的 pom.xml

    <spring.version>3.1.0.RELEASE</spring.version>
    <hibernate.version>4.2.0.Final</hibernate.version>

对于我的 Session factoru 的调用，我做了一个看起来像这样的 DaoUtil：

public class DaoUtils {

@Autowired
protected LocalSessionFactoryBuilder localSessionFactoryBuilder;


protected SessionFactory getSessionFactory()
  {
    return localSessionFactoryBuilder.buildSessionFactory();
  }
}

我这样称呼它：

@Component
public class DaoPersonne extends DaoUtils{

public void save(Person p) {
     this.getSessionFactory().getCurrentSession().save(p);
}
public List<Person> getPersonneAll()
 {
   return this.getSessionFactory().getCurrentSession().
        createQuery("FROM Person").list();
 }
}

我得到的错误信息是：

在我在网上看到之后，它看起来像是一个 Maven 问题，但我已经以这种方式尝试了不同的方法，但没有结果。

  1. 清洁和建造
  2. 删除 .m2 目录并重新下载所有依赖项
  3. 运行 mvn 依赖项：tree

但是问题仍然存在，并且开始让我很恼火。有人可以给我一些提示来发现问题出在哪里吗？

我知道我可以通过使用我更了解的旧版本的hibernate和Spring来解决这个问题，但我想练习hibernate 4.0。

谢谢

使用的hibernate版本是4，所以需要把spring hibernate包从3改成4，即：

  • 更改org.springframework.orm.hibernate3.HibernateTransactionManager为org.springframework.orm.hibernate4.HibernateTransactionManager

编辑1：

更改org.springframework.orm.hibernate4.LocalSessionFactoryBuilder为org.springframework.orm.hibernate4.LocalSessionFactoryBean

LocalSessionFactoryBuilder没有默认构造函数，非常基本的构造函数DataSource作为参数。所以将sessionFactory定义更改为

<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBuilder">        
    <constructor ref="dataSource" />

    <property name="packagesToScan" value = "test.entity"/>        
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">
                org.hibernate.dialect.HSQLDialect
            </prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.hbm2ddl.auto">create</prop>
        </props>
    </property>
</bean>
