NoSuchBeanDefinitionException：找不到依赖项

Question

我无法解决其他类似帖子的问题。我试图在Spring Boot中使用Hibernate。使用这种配置的其他项目工作正常。这个没有。也许你们其中一个人知道如何解决这个问题。

这是我的配置

<context:component-scan base-package="de.xxx.gatrinws"/>

<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

<bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

<tx:annotation-driven transaction-manager="txManager"/>

这是我的Dao，其中sessionFactory的自动装配似乎不起作用： （类文件位于：de.xxx.gatrinws.service，因此组件扫描应该有效，不应该吗？）

@Repository 
@Transactional
public class PriceDaoHibernateImpl implements PriceDao {

private final SessionFactory sessionFactory;

@Autowired
public PriceDaoHibernateImpl(@Qualifier(value = "sessionFactory") SessionFactory sessionFactory) {
    this.sessionFactory = sessionFactory;
}

@Override
public Product findProduct(String ean) {
   return null; // to be added
}

}

有谁知道如何解决这个问题？服务自动装配就像一个魅力。 sessionFactory配置似乎有问题。但是：这就是我为其他项目工作的方式。

提前致谢！

（如果您想知道：我x包了基本名称）

修改

它＆＃34;似乎＆＃34;在运行时将applicationContext.xml（Spring Config）复制到/ target /并且无法解析某些属性。我是否需要在可以正确解析属性的任何位置添加目标文件夹？ see screenshot here

未复制的配置可以毫无问题地解析所有属性。

Answer 1

您是否尝试使用自动装配的注释？如下所示：

    @Autowired
    private SessionFactory sessionFactory;
