找不到springboot Crudepository

我对springboot还不熟悉，只是在用它做一个学习项目。我把地狱世界搞定了，正在进入数据库。我在示例的基础上添加了一个repository类，并获得以下内容。这是基于搜索很多人得到的。问题是我所看到的解决方案并不能解决我的问题。我的存储库位于主类的子包中。我现在有一个“数据”和“控制器”子包。我试过一些建议，但似乎没有一个能解决我的问题。相关消息来源如下。

Description:

Field assets in mypkg.microsvc.controller.AssetController required a bean of type 'mypkg.microsvc.data.AssetRepository' that could not be found.

The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)

Action:

Consider defining a bean of type 'mypkg.microsvc.data.AssetRepository' in your configuration.

实体（注意我有一个@entity注解）

package mypkg.microsvc.data;
import javax.persistence.Entity;
[...]
@Entity
@Table(name = "ASSET_T", schema = "K702PRDR")
public class Asset implements java.io.Serializable  { 
  private static final long serialVersionUID = -4631085917731566134L;

  @Id
  @Column(name = "ASSET_ID", unique = true, nullable = false)
  private String assetId;
[...]

repository接口（我尝试过使用和不使用注解，扩展crudrepository和jparepository）

package mypkg.microsvc.data;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;
[...]

@Repository
public interface AssetRepository extends JpaRepository<Asset, String> {
  public List<Asset> findAll();
}

应用程序对象（我尝试了许多不同的注解，试图让它扫描并查看我的存储库，如您所见……这甚至不是所有的迭代。据我所知，鉴于我的app对象位于包层次结构中的存储库之上，我应该只需要@springbootapplication注解。但我想证明，我已经尝试了所有这些事情，我得到了同样的结果。）

package mypkg.microsvc;
[...]
@SpringBootApplication(scanBasePackages={
    "mypkg.microsvc", 
    "mypkg.microsvc.controller", 
    "mypkg.microsvc.data"})
//@EnableJpaRepositories("mypkg.microsvc.data")
//@EntityScan("mypkg.microsvc.data")
@ComponentScan(basePackages={
    "mypkg.microsvc", 
    "mypkg.microsvc.controller", 
    "mypkg.microsvc.data"})
public class MicroApplication {
  public static void main(String[] args) throws Exception {
    SpringApplication.run(MicroApplication.class, args);
}
}

这是我的控制器。我又经历了几次迭代

package mypkg.microsvc.controller;

 [...]
 import mypkg.microsvc.data.Asset;
 import mypkg.microsvc.data.AssetRepository;

 @RestController
 @EnableAutoConfiguration
 public class AssetController {
   @Autowired
   AssetRepository assets;

   @RequestMapping(value="/list", method=RequestMethod.GET, produces=MediaType.APPLICATION_JSON_VALUE)
   public @ResponseBody List<Asset> list() {
     return assets.findAll();
   }
}

我的印象是，这是它应该采取的一切。我在哪里搞砸了？

Description:

Field assetSuppository in gov.usdoj.afms.microsvc.service.AssetService required a bean of type 'gov.usdoj.afms.microsvc.repository.AssetRepository' that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)

Action:

Consider defining a bean of type 'gov.usdoj.afms.microsvc.repository.AssetRepository' in your configuration.

我有点困惑，因为我很确定我以前做过，但它没有工作，但添加@enablejparepositories到应用程序类没有任何包规范，同时删除其他无关的注解为我工作。我还在存储库和控制器之间添加了一个assetservice，尽管我这样做时它不起作用，所以它不是真正的解决方案。。
但这似乎让我犯了下一个错误-

Field assetRepository in gov.usdoj.afms.microsvc.service.AssetService required a bean named 'entityManagerFactory' that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)

Action:

Consider defining a bean named 'entityManagerFactory' in your configuration.

所以我还没开始工作，但这个问题已经解决了。

为了使spring-boot应用程序保持简单，应该遵循打包结构，这样spring-boot就可以扫描包并创建用于自动布线的bean。
在您的情况下，包结构应该如下
microapplication.java应该在mypkg.microsvc包中
assetcontroller.java应位于mypkg.microsvc.controller包中
assetrepository.java应位于mypkg.microsvc.repository包中
asset.java应该在mypkg.microsvc.entity包中
这种打包结构允许spring引导应用程序自动扫描所有包。这样，您就不必在主应用程序类中添加所有额外的锅炉板代码。spring-boot应用程序的目的是尽可能减少锅炉板代码

@SpringBootApplication
public class MicroApplication {
  public static void main(String[] args) throws Exception {
    SpringApplication.run(MicroApplication.class, args);
  }
}
