I had the same problem with IntelliJ IDEA 13.1.4
I solved it by removing the Spring facet (File->Project Structure) and leaving it to just show "Detection".

If you know that the bean exists and its just a problem of the inspections, then just add the following before the variable declaration:

Sometimes IntelliJ cannot resolve if a bean has been declared, for example when the bean is included conditionally and the condition resolution happens dynamically at runtime. In such a case it seems the static code analyzer of IntelliJ cannot detect the bean.

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.

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.

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.

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 

<blockquote>
 File > Project Structure > Modules > [your project name in the right panel] > Spring 
</blockquote>

Sometimes, we need to explicitly tell the IDE that the spring configuration is coming from a dependency (a jar present in your project classpath)

blocks|key|162366|text|我也有同样的问题。我的原因是，包含自动装配引用的bean不是Spring组件(它是一个EJB)，而是获得了一个允许使用自动装配的SpringBeanAutowiringInterceptor拦截器。我认为Intellij在其自动检查中不会考虑这种可能性。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|162367|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

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.

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 <a href="https://stackoverflow.com/questions/37565186/spring-couldnt-autowired-there-is-more-than-one-bean-of-type">this</a>, but my issue wasn't related to implementing the same interface twice. Using <code>@Qualitier</code> 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 <code>@Repository</code> class that was <code>@Autowired</code> in a <code>@Service</code> class which was also had the <code>@ComponentScan</code> annotation. I noticed that I also had a spring <code>application-config.xml</code> that was doing a <code>context:component-scan</code> 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 <code>@ComponentScan</code> was already implemented I just removed the <code>application-config.xml</code> and the issue was solved.

blocks|key|162534|text|我用这种方法解决了这个问题。在IntelliJ中，所有的包都应该在一个子包中，这个子包是main/java的子包。例如，我将我所有的包放在src/main/java/com.misisol.watchStore/下，然后spring就可以找到我的bean了。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|162535|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I've solved this problem this way.
In IntelliJ all of your packages should be in a sub package which is the sub package of main/java.
For example I've put all of my packages under src/main/java/com.misisol.watchStore/ and spring could find my beans then after.

blocks|key|2972026|text|使用@Qualifier注入Bean为我解决了这个问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2972027|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Inject Bean with @Qualifier solved the problem for me.

blocks|key|163824|text|我也遇到过类似的问题。我通过取消选中“处理显式注释的bean”选项(见下面的屏幕截图)解决了这个问题。在linux上，默认情况下启用此选项。现在，@Service和@Configurations注释是可见的。screenshot|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|163825|entityMap|0|LINK|mutability|MUTABLE|url|https://i.stack.imgur.com/Ku9P0.jpg^0|2W|A|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

I had similar problem. I solved it by unchecking "Process explicitly annotated beans" option (see screenshot below). This option is enabled by default on linux. 
Now @Service and @Configurations annotations are visible.

blocks|key|2972177|text|下面的方法对我很有效：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2972178|2972179|查找出现错误的实现服务(接口)的所有类。|ordered-list-item|2972180|使用@Service注解标记这些类中的每一个，以将它们指示为项目的业务逻辑。|2972181|2972182|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|L|8|@]|9|@]|A|$]]|$1|C|3|D|5|E|7|M|8|@]|9|@]|A|$]]|$1|F|3|G|5|E|7|N|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|P|8|@]|9|@]|A|$]]]|J|$]]

The following worked for me:

<ol>
<li>Find all classes implementing the service(interface) which is giving the error.</li>
<li>Mark each of those classes with the @Service annotation, to indicate them as business logic classes.</li>
<li>Rebuild the project.</li>
</ol>

blocks|key|162716|text|在IntelliJ的2019.2.4版本中，我只有一个基于构造函数的依赖注入服务遇到了这个问题。我发现更改服务的名称(shift+%2B+f6)然后放弃git级别的更改很有帮助。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|162717|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

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.

IntelliJ IDEA is showing errors when I use Spring's <code>@Autowired</code> annotation in the class, but the class is functioning without any problem.

Here is this error message: 

<blockquote>
 Autowired members must be defined in the valid spring
 bean (@Component/@Service,etc.) less... (Ctrl+F1) Checks autowiring
 problems in a bean class.
