빈 만들기 오류 - 봄 부팅

Question

나는 Spring Boot을 사랑합니다. 정말이에요! Spring-Boot 1.4.1, Java 8 and MongoDB을 사용하고 있으며 다음과 같은 클래스를 정의했습니다.

package builds; 

import java.util.List; 

import org.springframework.data.mongodb.repository.MongoRepository; 
import org.springframework.stereotype.Repository; 

@Repository 
public interface BuildsRepository extends MongoRepository<Build, String> { 

    List<Build> findByProvider(String provider); 

    List<Build> findByDeployer(String deployer); 
} 

그런 다음 모델 Builds : 나는 BuildsController에 Build 및 BuildRepository을 마지막으로

package builds; 

import java.text.DateFormat; 
import java.text.SimpleDateFormat; 
import java.util.Date; 

import javax.validation.constraints.Min; 
import javax.validation.constraints.NotNull; 
import javax.validation.constraints.Size; 

import org.bson.types.ObjectId; 
import org.springframework.data.annotation.Id; 
import org.springframework.data.mongodb.core.mapping.Document; 

import com.fasterxml.jackson.databind.annotation.JsonSerialize; 
import com.fasterxml.jackson.databind.ser.std.ToStringSerializer; 
import com.google.gson.Gson; 

@Document(collection = "builds") 
public class Build { 

    @Id 
    @JsonSerialize(using = ToStringSerializer.class) 
    private String id; 
    private String date; 

    @NotNull 
    @Size(min=2) 
    private String configuration; 

    @NotNull 
    private String provider; 

    @NotNull 
    private String deployer; 

    @NotNull 
    @Min(0) 
    private Integer instances; 

    public Build() { 
    } 

    public Build(String configuration, Integer instances, String provider, String deployer) { 
     this.id = new ObjectId().toHexString(); 
     DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss"); 
     this.date = dateFormat.format(new Date()); 
     this.configuration = configuration; 
     this.provider = provider; 
     this.instances = instances; 
     this.deployer = deployer; 
    } 

    public Integer getInstances() { 
     return this.instances; 
    } 

    public void setInstances(Integer instances) { 
     this.instances = instances; 
    } 

    public String getProvider() { 
     return this.provider; 
    } 

    public void setProvider(String provider) { 
     this.provider = provider; 
    } 

    public void setDeployer(String deployer) { 
     this.deployer = deployer; 
    } 

    public String getDeployer() { 
     return this.deployer; 
    } 

    public String getDate() { 
     return this.date; 
    } 

    public void setDate(String date) { 
     this.date = date; 
    } 

    public String getConfiguration() { 
     return this.configuration; 
    } 

    public void setConfiguration(String configuration) { 
     this.configuration = configuration; 
    } 

    @Override 
    public String toString() { 
     Gson gson = new Gson(); 
     return gson.toJson(this); 
    } 
} 

사용하고 있습니다 :

package tools; 

@Controller 
public class BuildsController { 

    private final static Logger logger = Logger.getLogger(BuildsController.class); 

    @Autowired 
    private BuildsRepository buildsRepository; 

    public BuildsController() { 
    } 

    /* 
    * Add the builds url page 
    */ 
    @GetMapping("/builds") 
    public String index(Model model) { 
     model.addAttribute("build", new Build()); 
     return "builds"; 
    } 

    /** 
    * 
    * @param object 
    * @return 
    */ 
    @PostMapping("/builds") 
    public Build deploy(@ModelAttribute Build build) { 
     this.buildsRepository.save(build); 
     return build; 
    } 
} 

을하지만, 모든 모델 중 하나 Document 또는 Service I로 비슷한 방식으로 만들면 이미 같은 오류가 발생하므로 죄책감이 있어야한다고 생각합니다. 비 유적의 문제 :

내 Application 클래스는 매우 간단하다 :

는

package tools; 

@SpringBootApplication 
@EnableMongoRepositories(basePackages = "tools") 
public class Application implements CommandLineRunner { 

    /* Use the User collections */ 
    @Autowired 
    private UserRepository repository; 

    public final static Logger logger = Logger.getLogger(Application.class); 

    public static void main(String[] args) throws Throwable { 
     SpringApplication.run(Application.class, args); 
    } 

    @Override 
    public void run(String... args) throws Exception { 

     this.repository.deleteAll(); 
     // .. 
    } 
} 

는 누군가가 해결 방법을 나에게 단서를 얻을 수 있을까요? 나는 최근에 이것으로 너무 많이 snakebitten했습니다.

* 편집Application.java 클래스에 @EnableMongoRepositories(basePackages = "tools")을 추가했습니다.

Answer 1

은 내가 저장소 및 모델 클래스의 패키지 이름은 이를 구축 것을 볼 수 있었다 당신이 당신의 컨트롤러 클래스

@EnableMongoRepositories (basePackages = "도구")

Answer 2

에 주석 @EnableMongoRepositories 누락 생각합니다.

@EnableMongoRepositories(basePackages = "builds") 

Answer 3

문제가 다른 콩 builds 패키지에있는 동안 Application 클래스는 tools 패키지에 있다는 것입니다 저장소를 사용하려면 다음과 같이 따라서, 패키지 이름을 지정합니다. 그들은 같은 수준에 있습니다. 따라서 자동 구성은 tools 패키지와 tools 패키지 내에 만들어진 모든 패키지에만 적용됩니다. 모든 것을 작동 시키려면 기본 패키지 (builds 패키지보다 한 패키지 레벨) 또는 builds 패키지 (다른 빈과 같은 레벨)로 Application 클래스를 이동하면 모든 것이 작동합니다. 이 경우 @SpringBootApplication 주석이 자동 구성을 사용 중이므로 @EnableMongoRepositories 주석이 필요하지 않습니다.
