Adding javax.servlet-api dependency throws exception that org.slf4j.impl.StaticLoggerBinder faild to load but i don't use sl4j, i use thymeleaf - spring

Question

Basicaly title. I'm trying to run simple spring5 + thymeleaf project. If i don't add servlet-api i get an error that
cannot access javax.servlet.ServletException
But if i add servlet-api, project starts and works fine , but i get an error on startup:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
But i don't use sl4j, i use thymeleaf. How does servlet exception connected with sl4j and how should i manage it?
UPD
I understand that my question is wrong. But i need help with connected problem:
As someone suggested i added
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.5</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.7.5</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
</dependency>
But i still get Failed to load class "org.slf4j.impl.StaticLoggerBinder". exception. Any ideas?
UPD
as someone mentioned here this is a bug of ide

Answer 1

Add slf4j.jar in your dependency or your project. Spring internally use slf4j for its own logging.

Answer 2

I'm using IntelIj idea.
As someone sugested i added log4j and sl4j dependencies becouse servlet-api uses loging by default. And my exception that class is failed to load is just a bug of ide as it was mentioned in another question and everything including logging works fine.
