Spring Boot似乎無法找到存儲庫

Question

我不確定我的配置有什麼問題，但據我所知應該是正確的，儘管Spring宣稱沒有這樣的bean定義。我veryfied以下幾點：

• 的配置類是根包一切
• 存儲庫擴展JpaRepository的，因此不需要註解
• 玩家對象標註有「@Entity」
• 此存儲庫的pojo完全按照註釋映射
• 不存在非java配置文件
• 數據庫已設置並使用正確的憑據。
• 爲了開發目的，Jpa/hibernate設置爲「Create-Update」。

這裏是我完整的調試日誌： spring startup log pastebin

日誌，而無需調試標誌：

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); 

} 

調用服務：

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; 
}

編輯：看來，從聚甲醛去除彈簧數據的JPA起動器，再經過重新插入它現在自動裝配密碼編碼器也有問題。 春天做自動裝配的方式有一個普遍的問題嗎？

Answer 1

顯然，在項目結構的某處，有一個不同版本的存儲庫和一個不同版本的播放器。

雖然通常我會指望Spring產生一個錯誤，告訴我有多個服務具有相同的類型描述，我懷疑由於player和playerRepository都是重複的，所以這種機制並沒有產生預期的錯誤方法，而是告訴我，沒有這個名字的服務。

Answer 2

您應該添加

@Repository(value = "playerRepository") 

註釋只是你的類

Answer 3

上面我相信你可能已經檢查了這一切，但爲了以防萬一，
