[Spring] MongoRepository bean을 찾을 수 없을 때

by 스뎅(thDeng) on

간단히 아래와 같은 package 구조의 웹서비스를 만들었을 때, MongoRepository bean을 찾지 못 하게 된다.

package my.project.web;
public class MyController {
    private MyService service;
package my.project.service;
public class MyService {
    private MyMongo mongo;
package my.project.repository;
public interface MyMongo extends MongoRepository<String, String> {
package my.project;
@ComponentScan(basePackages = "my.project")
public class MyApplication {
    	public static void main(String [] args) {
        SpringApplication.run(EyedropperApplication.class, args);


2016-01-22 03:28:50.403 ERROR 19424 --- [           main] o.s.boot.SpringApplication               : Application startup failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'service': Injection of autowired dependencies failed; nested exception is .........
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [my.project.repository.MyMongo] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

원인은 project 구성 때문에 MyMongo bean이 생성되지 않는 것이다. MyMongo를 찾을 수 있도록 도와주자. 아래에서 맘에 드는걸로 하나 골라주면 간단히 끝. :D


@EnableMongoRepositories(basePackages = "my.project")
@EnableMongoRepositories(basePackages = "my.project.repository")
@EnableMongoRepositories(basePackageClasses = my.project.repository.MyMongo.class)
@EnableMongoRepositories(basePackageClasses = my.project.repository.RepositoryScanBase.class)
