如何在 Spring java 中设置存储库？

【中文标题】如何在 Spring java 中设置存储库？【英文标题】：How to set Repositories in Spring java? 【发布时间】：2019-08-20 21:51:10 【问题描述】：我在 Spring 中的存储库有问题。 我创建了两个模块 - spring-data 和 spring-mvc。在 spring-data 中有几个包：模型、服务和存储库。最后是给我带来了一点麻烦。没有存储库包，应用程序正在运行，但是当我添加这个包时，应用程序运行失败。在存储库中，我只有一些扩展 CrudRepository 的基本接口。没有代码。
这是存储库的类之一。
package com.ubereats.repositories;
import com.ubereats.model.Basket;
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;
@Repository
public interface BasketRepository extends CrudRepository<Basket, Long>
这是控制台日志：

【问题讨论】：
你能再分享一些代码吗？ 【参考方案1】：看来
com.ubereats.model.Basket
类没有被标记为@Entity、或，它没有被 Spring 扫描，因此注册为 JPA 实体。这是什么
java.lang.IllegalArgumentException: Not a managed type
想告诉你。
您需要展开扫描的包，或，确保该类使用@Entity注解。
附带说明，您不需要注释您的存储库
@Repository
public interface BasketRepository extends CrudRepository<Basket, Long>
这样
public interface BasketRepository extends CrudRepository<Basket, Long>
没问题。
【讨论】：
谢谢伙计。我删除了 Basket 服务和存储库，现在它可以工作了 :) 非常感谢。 @mkaczynski 我还添加了关于存储库的注释，请在底部查看！ 在this 上抢夺;)【参考方案2】：看起来存储库 bean 无法启动，因为它正在寻找您的 com.ubereats.model.Basket 对象。我确定该对象存在，但您可能需要在类定义上方有一个 @Entity 声明。无论如何，一旦您的 BasketBean 一切正常，您应该会看到改进。
【讨论】：
以上是关于如何在 Spring java 中设置存储库？的主要内容，如果未能解决你的问题，请参考以下文章
我应该如何在Mercurial存储库中设置我的Visual Studio项目/解决方案？
