需要一个找不到类型的 bean

Question

I made some rest api's in my project. I have their models, repositories, controllers and services. They were working fine and My sql server has successfully created all the tables as well.

Now I am trying to implement role based authorisation for my apis for which I created a usersauth and a role model. This is the code that I am following:

https://github.com/TechPrimers/spring-security-db-example

Configuration.java:

//import statements
@EnableGlobalMethodSecurity(prePostEnabled = true)
@EnableJpaRepositories(basePackageClasses = UsersAuthRepository.class)
@EnableWebSecurity
@Configuration
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

Application.java:

  @SpringBootApplication


 public class Application {

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

When I run my project It gives me this error:

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

Description:

Field BlankRepository in 

required a bean of type 


that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 
'BlankRepository' in 
 your 
 configuration.

Now this is one of the model that I created previously before implementing authorization. The table is there in sql server as well. It is giving this error after implementing authorisation. I have the required repository for this as well. I am new at spring boot but I think this error has something to do with the

  @EnableJpaRepositories(basePackageClasses = UsersRepository.class)

above in my file. Maybe my application is not reading those repos or something. I still dont quite understand the purpose behind this line so can anybody please help me what am i missing?hanks!

Answer 1

add annotatil

@SpringBootApplication(scanBasePackages={xxx})

or

@Repository
public interface UsersRepository extends JpaRepository<Users, Integer> {
    Optional<Users> findByName(String username);
}
