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

Answer 1

Remove .iml file from all your project module and next go to File -> Invalidate Caches/Restart

Answer 2

I fixed it by adding the supress warning:

 @SuppressWarnings("SpringJavaInjectionPointsAutowiringInspection")
 @Autowired
 private ....

Answer 3

You should check if you have @Component, @Repository or similar added on the class

Answer 4

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. screenshot

Answer 5

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.

Happy Coding!

Answer 6

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.
