Adding a specific components to the Spring Context when creating a facade component

Question

Rather than making some of my classes @Autowire many small @Component s, I wanted to create a single @Component that would collect and just forward to the smaller @Component s.

Coding itself isn't too difficult, but when it comes to testing, it becomes cumbersome because now I have to add it to the @ContextConfiguration(classes) . Is there a way of doing it so I don't have to manage it individually?

Using @ComponentScan adds the whole package which I may not want because it will trigger more @MockBean to be created.

Answer 1

In my opinion what you are looking for is a combination of @Configuration + @Bean . Instead of marking all your nested subcomponents with @Component you can initialize the complete chain via @Bean and work with simple pojo-s instead of spring managed beans. At the end of course the end result will be a spring managed bean, but the initialization process, you can initialize it from anywhere with spring , or without spring.

With regards of ComponetScan. Usualy if I want to load only a certain section I create annotation with explicit patter of the conponenbt scan I want and then I use it accross the domain I want.

Example, lets say we have two sets of Mapper classes one is regarding Order the other is regarding inventory. I can create annotation @EnableOrderMappers and annotation @EnableInventoryMappers with appropriate component scann annotation on them.
