What you need to do is add     ComponentScan  package include your annotation component    in AppConfiguration java     Since I think your AppConfiguraion java s package is deeper than your annotation component   Service   Component     s package     such as  package include your annotation component deeper config

Surprisingly  A Feign oriented project that successfully ran with Eclipse could not run in InteliJ  When started the application  InteliJ complained about the Feign client I tried to inject to the serviceImpl layer saying  field personRestClient  my Feign client  in     required a bean of type     that could not be found  Consider defining a bean of type        in your configuration   I wasted a long time trying to understand what is wrong  I found a solution  for InteliJ  which I do not completely understand    Alt Shift F10  or run menu  Select  Edit configuration  In configuration window  Check the checkbox  include dependencies with   Provided  scope  Run your application   Or choose Eclipse

For me the solution was to place  EnableAutoConfiguration in the Application class under the  SpringBootApplication its going to underline it because its redundant  Delete it and voila all you warnings regarding missing beans are vanished  Silly Spring

Add Spring annotation  Repository over the repository class    I know it should work without this annotation  But if you add this  IntelliJ will not show error     Repository public interface YourRepository           If you use Spring Data with extending Repository class it will be conflict pagkages  Then you must indicate explicity pagkages   import org springframework data repository Repository        org springframework stereotype Repository public interface YourRepository extends Repository lt YourClass  Long gt                And next you can autowired your repository without errors    Autowired YourRepository yourRepository    It probably is not a good solution  I guess you are trying to register repositorium twice   But work for me and don t show errors    Maybe in the new version of IntelliJ can be fixed  https   youtrack jetbrains com issue IDEA-137023

My solution to this issue in my spring boot application was to open the spring application context and adding the class for the missing autowired bean manually    access via Project Structure menu or spring tool window    edit  Spring Application Context    So instead of SpringApplicationContext just containing my ExampleApplication spring configuration it also contains the missing Bean   SpringApplicationContext    ExampleApplication java MissingBeanClass java   et voil    The error message disappeared

I had similar issue in Spring Boot application  The application utilizes Feign  HTTP client synthetizing requests from annotated interfaces   Having interface SomeClient annotated with  FeignClient  Feign generates runtime proxy class implementing this interface  When some Spring component tries to autowire bean of type SomeClient  Idea complains no bean of type SomeClient found since no real class actually exists in project and Idea is not taught to understand  FeignClient annotation in any way   Solution  annotate interface SomeClient with  Component   In our case  we don t use  FeignClient annotation on SomeClient directly  we rather use metaannotation  OurProjectFeignClient which is annotated  FeignClient and adding  Component annotation to it works as well

It can be solved by placing  EnableAutoConfiguration on spring boot application main class

User · Answer

Sometimes you are required to indicate where  ComponentScan should scan for components  You can do so by passing the packages as parameter of this annotation  e g    ComponentScan basePackages   path to my components   path to my othercomponents      However  as already mentioned   SpringBootApplication annotation replaces  ComponentScan  hence in such cases you must do the same      SpringBootApplication scanBasePackages   path to my components   path to my othercomponents      At least in my case  Intellij stopped complaining

Use  EnableAutoConfiguration annotation with  Component at class level  It will resolve this problem  For example   Component  EnableAutoConfiguration   public class ItemDataInitializer          Autowired     private ItemReactiveRepository itemReactiveRepository        Autowired     private MongoOperations mongoOperations

I had this same issue when creating a Spring Boot application using their  SpringBootApplication annotation  This annotation represents  Configuration   EnableAutoConfiguration and  ComponentScan according to the spring reference   As expected  the new annotation worked properly and my application ran smoothly but  Intellij kept complaining about unfulfilled  Autowire dependencies  As soon as I changed back to using  Configuration   EnableAutoConfiguration and  ComponentScan separately  the errors ceased  It seems Intellij 14 0 3  and most likely  earlier versions too  is not yet configured to recognise the  SpringBootApplication annotation   For now  if the errors disturb you that much  then revert back to those three separate annotations  Otherwise  ignore Intellij   your dependency resolution is correctly configured  since your test passes   Always remember        Man is always greater than machine

Putting  Component or  configuration in your bean config file seems to work  ie something like     Configuration public class MyApplicationContext        Bean     public DirectoryScanner scanner             return new WatchServiceDirectoryScanner   tmp myDir              Component public class MyApplicationContext        Bean     public DirectoryScanner scanner             return new WatchServiceDirectoryScanner   tmp myDir

User · Answer

And one last piece of important information - add the ComponentScan so that the app knows about the things it needs to wire   This is not relevant in the case of this question   However if no  autowiring is being performed at all then this is likely your solution    Configuration  ComponentScan basePackages          some package      public class someService
