Java Consider defining a bean of type in your configuration exception when add mongoDB support

Question

I have a very simple Java Springboot project connect to the database. Still, I want a mongoDB connection and I could use mongoDB as well.

I read lots of document and I can't make it work. And my commits code is:

https://github.com/GuoJing/spb/commit/20c04ce38d43bb0ba229d0d3577fdccbd571062e

If adding @AutoWired annotation, application will not start. I think this should be same as official document.

in src/main/java/controller/UserController.java

@Autowired
private UserPropsRepository userPropsRepository;

Here is my project, could anybody help me?

My Exception is:

***************************
APPLICATION FAILED TO START
***************************

Description:

Field userPropsRepository in controller.UserController required a bean of type 'repository.UserPropsRepository' that could not be found.


Action:

Consider defining a bean of type 'repository.UserPropsRepository' in your configuration.

Answer 1

Problem solved.

1. Change my project structure, move root Package and Model and Dao ... to com.example.model ...
2. Move Application.java to root so it will scan components automatically

Answer 3

suppose you are missing @Repository annotation in the UserPropsRepository interface.

   @repository("userPropsRepository")
   public interface UserPropsRepository extends MongoRepository<UserProps, String> {
    UserProps findOne(String id);
    UserProps save(UserProps props);
    UserProps update(UserProps props);
    void delete(UserProps props);
}
