Spring boot not scanning components and configurations

Question

I have a multi-module project:

TOP_LEVEL
|-> core
|-> assetManager
'-> requestManager

So, I have a core module which has Application class in the core module.

In my assetManger build.gradle I compile(project(:core))

The application main class is in package : com.test.companydomain.core of the core module. This Application class is annotated with

@EnableAutoConfiguration
@ComponentScan(basePackages = {"com.test.companydomain"})
@EntityScan(basePackages = {"com.test.companydomain", "com.test.companydomain.assetManager"})
@EnableJpaRepositories
class Application {

}

There is a class ClientUtils in assetManager module in the package : com.test.domain.assetManager.server.common.utils;

annotated with :

@Slf4j
@Configuration
@Component("clientUtils")

There are beans that I am creating in this class and It uses other configuration classes for autowiring and creating beans.

The beans are not getting generated as of now from this ClientUtils class.

What can be a possible issue with this?

The error i see is

APPLICATION FAILED TO START

Description:

Field locationService in com.test.companydomain.assetManager.server.vendor.converter.ExternalVendorPojoConversionHelper required a bean of type 
'com.test.companydomain.assetManager.server.common.utils.client.LocationService' that could not be found.

This class LocationService is also annotated with @Component for spring to create its bean.

Answer 1

In your application , the main class is present in the package com.test.companydomain.core and by default springboot scans all classes and packages under the current package of the main application for autowiring beans. So , you have provided the annotation @ComponentScan to explicitly tell spring to scan other packages as well.But your util class is in the package com.test.domain.assetManager.server.common.utils , which is not included in the @ComponentScan annotation, so it is not taken up for component scanning.

Could you try adding the package com.test.domain to the component scan in main class like :

@EnableAutoConfiguration
@ComponentScan(basePackages = {"com.test.companydomain","com.test.domain"})
@EntityScan(basePackages = {"com.test.companydomain", "com.test.companydomain.assetManager","com.test.domain"})
@EnableJpaRepositories
class Application {
