다음과 같이 EnableWebMvcConfiguration 클래스에서 에러가 나는 경우가 있음

원인은 spring의 web 의존성을 가지고 있는데 org.springframework.web.servlet.HandlerExceptionResolver 클래스의 인스턴스를 만들지 못해서 발생하는 예외임

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'handlerExceptionResolver' defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.HandlerExceptionResolver]: Factory method 'handlerExceptionResolver' threw exception; nested exception is java.lang.NoSuchMethodError: org.springframework.boot.autoconfigure.web.servlet.WebMvcAutoConfiguration$EnableWebMvcConfiguration.addDefaultHandlerExceptionResolvers(Ljava/util/List;)V

Caused by: java.lang.NoSuchMethodError: org.springframework.boot.autoconfigure.web.servlet.WebMvcAutoConfiguration$EnableWebMvcConfiguration.addDefaultHandlerExceptionResolvers(Ljava/util/List;)V

해결책은 애플리케이션이나 테스트 코드에서 자동 설정 대상 중에서 WebMvcAutoConfiguration 클래스를 제외해주면 됨

@EnableAutoConfiguration(exclude = { WebMvcAutoConfiguration.class })
public class MyTests {

}
