why is spring boot's DataJpaTest scanning @Component -

confident hasn't been asked reading through spring docs , testing utilities found annotation , thought i'd start using it. reading through fine print read:

regular @component beans not loaded applicationcontext.

sounded , liked idea of using h2 except found entity wanted use had catalog , schema modifiers , default h2 couldn't figure out how support that. made h2 datasource test branch , use , override replace. wound

@runwith(springrunner.class) @contextconfiguration(classes=abch2congfiguration.class) @datajpatest @autoconfiguretestdatabase(replace= autoconfiguretestdatabase.replace.none) public class statusrepositorytest {  } 

however tests fails fro caused by: org.springframework.beans.factory.nosuchbeandefinitionexception: no qualifying bean of type. leads to: error creating bean name 'customerserviceimpl': unsatisfied dependency.

however customerserviceimpl bean:

@component public class customerserviceimpl  implements customerservice { } 

that says @component. fine print datajpatest says doesn't load @components. why doing , failing test?

as kyle , eugene asked below here's rest:

package com.xxx.abc.triage; @component public interface customerservice { }  configuration @componentscan("com.xxx.abc") @enablejparepositories("com.xxx.abc") //@profile("h2") public class abmh2congfiguration {      @primary     @bean(name = "h2source")     public datasource datasource() {         embeddeddatabase build = new embeddeddatabasebuilder().settype(embeddeddatabasetype.h2).setname("abc").addscript("init.sql").build();         return build;     }      @bean     public jpavendoradapter jpavendoradapter() {         hibernatejpavendoradapter bean = new hibernatejpavendoradapter();         bean.setdatabase(database.h2);         bean.setshowsql(true);         bean.setgenerateddl(true);         return bean;     }      @bean     public localcontainerentitymanagerfactorybean entitymanagerfactory(             datasource datasource, jpavendoradapter jpavendoradapter) {         localcontainerentitymanagerfactorybean bean = new localcontainerentitymanagerfactorybean();         bean.setdatasource(datasource);         bean.setjpavendoradapter(jpavendoradapter);         bean.setpackagestoscan("com.xxx.abc");         return bean;     }      @bean     public jpatransactionmanager transactionmanager(entitymanagerfactory emf) {         return new jpatransactionmanager(emf);     }  } 

and clarify question, why @component being loaded context within @datajpatest?

@componentscan automatically inject found @component , @service context. override separate @bean:

@bean customerservice customerservice{     return null; } 

or remove @component annotation customerservice , customerserviceimpl, should add @bean @ production @configuration
