#ComponentScanning-Error at Spring Boot Application with IntelliJ not with Eclipse - spring

Question

I'm working on a Spring Boot-Application which is using Maven for build management. I have imported this application to IntelliJ IDEA Ultimate 16.1. I got the following error if I run my main-class:

The code of this method (include error-point Application.java line 43 out of above message) is:
#EnableAutoConfiguration
#ComponentScan("com.applicationpackage")
#SpringBootApplication
#EnableScheduling
public class Application extends WebMvcConfigurerAdapter {
private static ConfigurableApplicationContext context;
#Autowired
private ServletContext servletContext;
public static void main(String[] args) throws Exception {
Application.context = SpringApplication.run(Application.class, args);
Application.context.registerShutdownHook();
}
...
}
There is no quicktip or error on this line of code displayed.
If I import it to Eclipse Neo it runs without any errors and I can access my web-application. If I run Maven install (e.g. out of IntelliJ) then the application is started for some test cases well, too. So it seems that the error is caused by an setting of IntelliJ. In project structure menu there are no problems displayed and the Spring Application Context is filled with Application (no "context-less classes" displayed).

Answer 1

You can try this :
Select:File -> Project Structure->Modules->Dependencies
Find:tomcat-embed-core (this jar package default is provided, change to compile)

Answer 2

You might be missing this dependency:
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>

Answer 3

I had the same problem (application running in eclipse, not in intellij).
In my pom.xml tomcat-embed-jasper and javax.servlet had scope provided.
I commented out these scopes and now everything works fine.
