java - Spring Boot 似乎没有找到 Repository

标签 java spring maven spring-boot

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。我验证了这些要点:

  • 配置类在其他一切的根包中
  • 存储库扩展了 JpaRepository，因此不需要注释
  • 播放器对象用“@Entity”注释
  • 这个存储库的 pojo 完全按照注释映射
  • 不存在非 java 配置文件
  • 数据库已设置并使用了正确的凭据。
  • 出于开发目的，Jpa/hibernate 设置为“Create-Update”。

这是我完整的调试日志: spring startup log pastebin

没有调试标志的日志:

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 SpringBoot 应用程序:

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:似乎在从 pom 中删除 spring-data-jpa-starter 然后重新插入它之后，它现在 Autowiring 密码编码器也有问题。 spring Autowiring 的方式是否存在普遍问题？

最佳答案

显然，在项目结构的某处，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 产生一个错误，告诉我有多个服务具有相同的类型描述，但我怀疑由于 player 和 playerRepository 都是重复的，这个机制没有产生预期的错误方法，而是告诉我我根本没有那个名字的服务。
