multi module component scanning not working in spring boot

Question

I am having two module web and business. I have included business in the web. But when I try to include a service interface from business into web using @autowired,

Answer 1

@SpringBootApplication only scans the packages of the class with the annotation itself and all packages below.

Example: If the class with the SpringBootApplication annotation is in the package com.project.web, then this packages and all below that are scanned.

However, if you have your services in the package com.project.business, the beans won't be scanned.

In that case you have to add the annotation @ComponentScan() to your application class, and add all packages you want to scan as value in that annotation, e.g. @ComponentScan({"com.project.web", "com.project.business"}).
