Spring boot custom starter , application doesn't find required bean

问题

http://www.baeldung.com/spring-boot-custom-starter

I have followed tutorial and github example provided from the link above and have implemented similar way. I am using spring-boot-starter-parent :2.0.0.M3. Even after including my custom starter dependency in the pom for the app, it doesn't find required bean without @componentScan while deploying it.

It is giving following error.

APPLICATION FAILED TO START

Description:

Field fooApiCaller in com.core.controller.TestController required a bean of type 'service.ApiCaller' that could not be found.

Action:

Consider defining a bean of type 'service.ApiCaller' in your configuration.

Sample App ( one throwing error) pom.xml

<dependency>
        <groupId>abc.def</groupId>
        <artifactId>custom-starter</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </dependency>
@Controller
public class FooController {
@Autowired
ApiCaller fooApiCaller
}
