[Spring] MongoRepository bean을 찾을 수 없을 때

스뎅(thDeng) on January 22, 2016

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

package my.project.web;
@Controller
public class MyController {
    @Autowired
    private MyService service;
}

package my.project.service;
@Service
public class MyService {
    @Autowired
    private MyMongo mongo;
}

package my.project.repository;
@Repository
public interface MyMongo extends MongoRepository<String, String> {
}
package my.project;
@EnableAutoConfiguration
@EnableMongoRepositories
@ComponentScan(basePackages = "my.project")
public class MyApplication {
    	public static void main(String [] args) {
        SpringApplication.run(EyedropperApplication.class, args);
    }
}

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

Solution:

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