java为什么我的Spring数据配置没有自动连接存储库接口？
首先，我想欢迎大家，虽然我是一名新成员，但我经常是一名匿名用户，在这里搜索我的问题的可能答案：）
我的Spring数据配置有一个非常严重的问题，我已经和这个问题斗争了两天，现在我想到了各种可能性/ 我以前创建过使用Spring Data JPA功能的项目，但没有像现在这样有太多问题/ 在这个过程中，我研究了多个网站，对我的配置做了一些改变，但没有任何帮助/
在我的spring配置xml文件中，我创建了以下bean：BasicDataSource、LocalContainerEntityManagerFactoryBean和一个JpaTransactionManager。 顺便说一句： 我使用的是Spring 4.1.6、Spring Data release 1.8.0和hibernate 4.3.8。决赛
以下是Spring配置文件：

</beans>
我正在尝试创建一个JpaRepository接口，它将处理实体上的基本db操作
该实体如下：
@Entity
@Table(name = "Recipie")
public class Recipie {
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "RecipiSeq")
@SequenceGenerator(initialValue = 1,
name = "RecipiSeq",
sequenceName = "RecipiSeq",
allocationSize = 1)
@Column(name = "RECIPIE_ID", unique = true)
private Integer recipieId;
@NotNull
@Column(name = "RECIPIE_NAME")
private String name;
@NotNull
@Column(name="RECIP_CAT")
private String category;
@NotNull
@Size(max = 255)
@Column
private String description;
@Digits(fraction = 0, integer = 3)
@Column(name = "READY_IN")
private Integer readyIn;
@Column
private String author;
@Column(name="iconFile")
private byte[] file;
public Recipie() {
}
// Setters and getters are here...
}
存储库是一个扩展JpaRepository的小界面
public interface RecipieRepository extends JpaRepository<Recipie, Integer>{
}
在部署时，我得到一个“NoSuchBeanDefinitionException”，带有以下stacktrace：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'recipieMock': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private pl.mmalik.portlet.common.repositories.RecipieRepository pl.mmalik.portlet.common.domain.model.mock.RecipieMock.recipieRepository; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [pl.mmalik.portlet.common.repositories.RecipieRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

我认为这与我对EntityManager或DataSource的配置有关，但研究这些元素的其他配置选项并没有给我带来任何好处/
如果有任何建议，我将不胜感激，我完全无法接受。 如果你需要任何关于配置的额外信息，我会更新这篇文章
# 1 楼答案
如果问题与DataSource或EntityManager有关，则会有一条消息通知您这些问题。但你没有。你得到的信息是
这意味着Spring找不到任何Springbean实现这个接口。您是否已将Spring配置为扫描该软件包
不，你没有
