Spring Boot 似乎没有找到 Repository
Posted
技术标签:
【中文标题】Spring Boot 似乎没有找到 Repository【英文标题】：Spring Boot doesn't seem to find Repository 【发布时间】：2017-11-13 08:11:50 【问题描述】：我不确定我的配置有什么问题，但据我所知，它应该是正确的，尽管 spring 宣布没有这样的 bean 定义。我非常认同以下几点：
配置类在其他所有东西的根包中 存储库扩展了 JpaRepository，因此不需要注释 播放器对象带有“@Entity”注解 此存储库的 pojo 完全根据注释映射 不存在非 java 配置文件 数据库已设置并使用正确的凭据。 出于开发目的，Jpa/hibernate 设置为“Create-Update”。这是我的完整调试日志： spring startup log pastebin
不带调试标志的日志：

Description:
Field playerRepository in de.awesome.corporate.newworlds.core.usermanagement.service.RegistrationService required a bean of type 'de.awesome.corporate.newworlds.core.usermanagement.repository.PlayerRepository' that could not be found.
Action:
Consider defining a bean of type 'de.awesome.corporate.newworlds.core.usermanagement.repository.PlayerRepository' in your configuration.
我的 SpringBootApplication：
package de.awesome.corporate.newworlds;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
@SpringBootApplication
public class NewWorldsApplication
public static void main(String[] args)
SpringApplication.run(NewWorldsApplication.class, args);
我的 PlayerRepository：
package de.awesome.corporate.newworlds.core.usermanagement.repository;
import org.springframework.data.jpa.repository.JpaRepository;
import de.awesome.corporate.newworlds.core.usermanagement.entity.Player;
public interface PlayerRepository extends JpaRepository<Player, String>
Player findByUserAccount(String useraccount);
调用服务：
package de.awesome.corporate.newworlds.core.usermanagement.service;
@Service
public class RegistrationService
@Autowired
private PlayerRepository playerRepository;
@Autowired
private UserAccountRepository userRepository;
@Autowired
private OrganizationCreationService organizationCreationService;
@Autowired
private BCryptPasswordEncoder passwordEncoder;

编辑：似乎从 pom 中删除 spring-data-jpa-starter 然后重新插入后，它现在自动装配密码编码器也有问题。 spring 自动装配的方式是否存在普遍问题？
【问题讨论】：
在问题本身中粘贴日志、POM 等。 现在，为什么我的问题被否决了？ 请不要让人们点击链接以获得完整的图片。将其添加到您的问题中。我也怀疑你所说的是你的 pom 是你实际的 pom 文件。请添加您的实际 pom 文件，而不是有效 pom.xml。 @M.Deinum 我已经处理了您的反馈。但是，我无法在启用 spring 调试的情况下发布整个日志，因为它超出了字符限制。 @harshavmb for JpaRepositories 您可以通过方法名称中的特定语法定义查询，看这里docs.spring.io/spring-data/jpa/docs/current/reference/html/… 【参考方案1】：显然，在项目结构的某个地方，有不同版本的存储库和不同版本的播放器。
虽然通常我希望 Spring 会产生一个错误，告诉我有多个具有相同类型描述的服务，但我怀疑由于 player 和 playerRepository 都是重复的，这种机制没有产生预期的错误方法，而是被告知我说根本没有该名称的服务。
【讨论】：
【参考方案2】：我的问题类似：我有多个 ORM 类和多个用于同一实体的存储库，这导致应用程序无法正常运行。
【讨论】：
以上是关于Spring Boot 似乎没有找到 Repository的主要内容，如果未能解决你的问题，请参考以下文章
Spring Boot with docker 无法找到请求目标错误的有效认证路径
Spring Boot JpaRepository 保存调用似乎没有做任何事情
