无法创建Spring Data JPA存储库

标签： java hibernate spring-data spring-data-jpa 

    @Repository
public interface JobRepository extends JpaRepository<Job, Long>{

}

这是我的存储库。我得到的错误如下。这似乎是一件非常简单的事情，我不确定如何搞砸它。

这是我试图坚持的pojo的一部分

    @XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
@Entity
@Table(name="whatever")
public class Job implements Comparable<Job>, Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @Column
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

我试图用尽可能少的xml来做这件事。我的主要课程上有以下注释

@SpringBootApplication
@EnableCircuitBreaker
@ImportResource({"classpath*:/META-INF/**/spring-bootstrap.xml"})
@EnableJpaRepositories

我在xml中定义了我的数据源，并且在我尝试进行故障排除时添加了一个实体管理器工厂，但我认为没有必要。

        <property name="driverClass" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />

请将存储库包添加到entityManagerFactory Bean 

<property name="packagesToScan" value="repository.package" />

答案 1 :(得分：0)

我明白了。我的enableJpaRepositories没有引用entityManagerFactory。

@EnableJpaRepositories(basePackages="package name", entityManagerFactoryRef="entityManagerFactory")

很难找到与春天相关的任何东西的正确的示例（或者就此而言java）。所有TIMTOWTDI都是杀手锏。
