WFLYCTL0080 Spring MVC java.lang.RuntimeException：java.nio.file.InvalidPathException

Question

I am new to Spring. I want to make Spring MVC hello world example using Spring boot starter project. I am using WildFly 12 to run the project. When I tried to run WildFly I faced this error

Answer 1

Just for others who will face this problem in the future, It seems like a problem in the integration between WildFly and Spring.

First I were missing @ComponentScan annotation on the WebConfig class

Second: I tried using Tomcat and it works just fine with this setup.

Also I used WildFly 9 instead of 12 and the error has changed to be

Caused by: java.lang.RuntimeException: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'requestMappingHandlerAdapter' defined in org.springframework.web.servlet.config.annotation.DelegatingWebMvcConfiguration: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter]: Factory method 'requestMappingHandlerAdapter' threw exception; nested exception is java.lang.VerifyError: Cannot inherit from final class

I made some researches about the new error and I found this link

http://forum.spring.io/forum/spring-projects/web/76349-cannot-create-bean-of-type-mappingjacksonhttpmessageconverter

which indicates that the problem in the used Jackson API version. I still could not make it run successfully on WildFly, but I wanted to share the latest status with you, just if anyone needed it in the future.
