  1. Consider defining a bean of type 'service' in your configuration [Spring boot]

    A class must have the @Component annotation or a derivation of that (like @Service, @Repository etc.) to be recognized as a Spring bean by the component scanning. So if you add @Component to the class, it should solve your problem.

I fixed the problem adding this line @ComponentScan(basePackages = {"com.example.DemoApplication"}) to main class file, just up from the class name

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@ComponentScan(basePackages = {"com.example.DemoApplication"})
public class DemoApplication {

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

}

I solved this issue by creating a bean for my service in SpringConfig.java file.
Please check the below code,

@Configuration 
public class SpringConfig { 

@Bean
public TransactionService transactionService() {
    return new TransactionServiceImpl();
}

}

The path of this file is shown in the below image,

Since TopicService is a Service class, you should annotate it with @Service, so that Spring autowires this bean for you. Like so:

@Service
public class TopicServiceImplementation implements TopicService {
    ...
}

This will solve your problem.
