IntelliJ IDEA无法解析spring数据jpa @query注释中的实体

这是我的repository界面:

public interface ContentRepository extends JpaRepository {

    @Query(value = "select c from Content c where c.ContentCategory.genre =  :genre and c.ContentType.genre = :contentType")
    Iterable findByTypeAndCategory(@Param("contentType") String contentType, @Param("genre") String genre);

}

这是ContentPOJO:

@Entity
@Table(name = "content")
public class Content implements Serializable {

public Content() {
}

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

@ManyToOne
private ContentCategory contentCategory;

@ManyToOne
private ContentType contentType;

// other methods }

在这里我的applicationContext.xml:

    
    
    
    



    



    
    

    
        
            
            
        
    
    
        
            update
        
    

编译器不能找到Content在@Query
