我有一个多模块 Spring-boot 应用程序，我有两个子模块:
- spring-boot-rest-api-todo-list
- 坚持
组织方式如下:

在我的rest-api模块中，我想扫描两个模块(持久性和restapi)，然后按如下方式进行:
@SpringBootApplication
@ComponentScan ({"com.medkhelifi.tutorials.springboot", "com.medkhelifi.tutorials.persistence"})
public class RestTodoListApplication {
@Autowired
private UserRepository userRepository;
public static void main (String[] args){
SpringApplication.run(RestTodoListApplication.class, args);
}
}
但是我收到了这个错误:
Field userRepository in com.medkhelifi.tutorials.springboot.restapi.todolist.RestTodoListApplication required a bean of type 'com.medkhelifi.tutorials.persistence.model.repositories.UserRepository' that could not be found.
Action:
Consider defining a bean of type 'com.medkhelifi.tutorials.persistence.model.repositories.UserRepository' in your configuration.
如果我删除 "com.medkhelifi.tutorials.spring-boot"从 ComponentScan 错误消失，但我的 Restapi 模块下的 Controller 将无法工作。
我尝试了 ComponentScan 的许多变体，但出现了相同的错误:
@ComponentScan ({"com.medkhelifi.tutorials"})
@ComponentScan ({"com.medkhelifi.tutorials.persistence", "com.medkhelifi.tutorials.springboot"})
最佳答案
我想我找到了解决方案，我添加了 @EnableMongoRepositories 来扫描我的持久性模块:
@EnableMongoRepositories(basePackages = "com.medkhelifi.tutorials.persistence")
