@ComponentScan(basePackages={"com.xx.common.core.config.mq"})
public class ProductApplication {
  public static void main(String[] args) {
    SpringApplication.run(ProductApplication.class, args);
  }

}

在Application上增加 @ComponentScan(basePackages={"com.xx.common.core.config.mq"})

即可访问lib中@Configuration
