How can I inject dependency from a library in Spring Boot 2?

Question

I have a library in which I defined a class let's say MyClass with @Component along with @Value but when I try to use this in my Spring Boot application and try to Autowire it, I get exception about Spring not being able to find this type and ask me to define a Bean. All other classes gets injected just fine that I have defined in the application it self.

How can I make the MyClass to be injected?

Answer 1

Without a complete information on about your library, how you are using it, we can't provide solution. Assuming everything on your library is correct, you can simply add @ComponentScan on the application that use your library.

Create a class as below and that should fix your problem.

@Configuration
@ComponentScan({"your library package"}) 
public class YourConfig {

}

If this doesn't solve your problem, add more information on your question and I will update my answer accordingly.
