IntelliJ IDEA shows errors when using Spring s Autowired annotation

Question

IntelliJ IDEA is showing errors when I use Spring s  Autowired annotation in the class  but the class is functioning without any problem   Here is this error message       Autowired members must be defined in the valid spring   bean   Component  Service etc   less     Ctrl F1  Checks autowiring   problems in a bean class

I got the same problem  Mine was because the bean containing the autowired reference was not a Spring component  it was an EJB   but got a SpringBeanAutowiringInterceptor Interceptor allowing the use of autowiring  I think Intellij don t take this possibility in its Autowiring inspection

Got the same error here   It seems the Intellij cannot verify if the class implementation is a  Service or  Component   Solve it just changing from Error to Warning Pressing Alt   Enter

I know this is an old question  but I haven t come across any answers that solved this problem for me so I ll provide my solution   Note  I thought the issue may have been this  but my issue wasn t related to implementing the same interface twice  Using  Qualitier did make my issue go away  but it was a bandage and not a proper solution so I didn t settle with that    BACKGROUND  I m tasked with maintaining an old project that has gone through different versions of spring and only updated for separate modules  so things needed refactoring  to say the least  I had initially gotten the duplicate bean issue and tinkering with things changed the issue back and forth between OP s issue and the duplicate bean issue even though there was only one bean  navigating to the duplicate beans always went to the same class   THE ISSUE  The issue was present on a  Repository class that was  Autowired in a  Service class which was also had the  ComponentScan annotation  I noticed that I also had a spring application-config xml that was doing a context component-scan on the base package  which I believe was the original approach in older versions of Spring  I was in the process of making a new branch by taking parts of an old branch and a newer branch in a support project that was used in different projects that were developed over several years and that is why there was such a mix-and-match of methodologies   SIMPLE SOLUTION  Since the more modern approach of using  ComponentScan was already implemented I just removed the application-config xml and the issue was solved

I might be a little late  but after spending hours and researching on this issue  I found out that in the latest version IntelliJ 2020  AutoWired is optional and constructor based depedency injection is preferable  I sloved the problem by simply removing the  AutoWired Annotation from Service and Controller class and using constructor based dependency injection  This link might help  Happy Coding

I fixed it by adding the supress warning     SuppressWarnings  SpringJavaInjectionPointsAutowiringInspection     Autowired  private

If you know that the bean exists and its just a problem of the inspections  then just add the following before the variable declaration    SuppressWarnings  SpringJavaAutowiringInspection    Inject MyClass myVariable    Sometimes IntelliJ cannot resolve if a bean has been declared  for example when the bean is included conditionally and the condition resolution happens at runtime

I had this problem with only one service with constructor based dependency injection with 2019 2 4 version of IntelliJ  I found it helpful to change the name of the service  shift   f6  and then discard the changes from the git level

The following worked for me    Find all classes implementing the service interface  which is giving the error  Mark each of those classes with the  Service annotation  to indicate them as business logic classes  Rebuild the project

Solved the issue by going to File    Project Structure    Facets and then adding all the configuration files to Spring Facet  After that it started detecting files in which the beans reside and was able to sort the issue  IntelliJ giving this check is quite valuable and IMHO shouldn t be disabled

User · Answer

Make sure you have your Spring bean definitions correct  Sometimes  the application works fine  it just displays an error in the IDE  check your project    iml    file if you have a Spring facet defined

a little late but i hope it helps to someone else   Make sure to put the  Service on the implementation class for the service   Service public class ServiceNameImpl implements ServiceName         Override     public void method ObjectType paramName              CODE            That s how i fixed the error

Make sure that your IntelliJ Idea  IDE  is aware of all the necessary spring configurations that your module is being inspected against   You can check this under      File   Project Structure   Modules    your project name in the right panel    Spring    Sometimes  we need to explicitly tell the IDE that the spring configuration is coming from a dependency  a jar present in your project classpath

Inject Bean with  Qualifier solved the problem for me

I had this problem too  Doing alt enter and then asking to either re-run or disable Spring inspection on the effected line fixed it  This only seems to have become an issue after the 13 4 update

It seems like the visibility problem - the parent controller doesn t see the Component you are trying to wire   Try to add    ComponentScan  path to respective Component      to the parent controller

I had the same problem  I solved it by adding the Spring facet  File- Project Structure  for each relevant module  and then add the configuration files  For some projects  spring mvc   the config files where detected automatically  However  for a jar project  I had to add the configuration files manually
