[SPRING] java.lang.IncompatibleClassChangeError : Mongo 클래스 구현

java.lang.IncompatibleClassChangeError : Mongo 클래스 구현

왜이 오류가 발생하는지 파악할 수 없습니다. 중복 된 libs 등을 정리하려고했습니다.

내가 할 때 오류가 발생 :

  mongo = new Mongo(host, port);

재미있는 점은 IDE (IntelliJ)에서 만든 단위 테스트를 실행할 수 있다는 것입니다.하지만 Tomcat을 통해 실행하려고하면 다음과 같이됩니다.

나는 jdk 7, tomcat 7.0.27, maven 3.0.3을 사용하고 있습니다.

해결법

1. ==============================

   1.바이트 코드 수준의 오류처럼 보입니다. 어쩌면 tomcat 서버에 동일한 라이브러리의 두 가지 버전이있을 수 있습니다.

   바이트 코드 수준의 오류처럼 보입니다. 어쩌면 tomcat 서버에 동일한 라이브러리의 두 가지 버전이있을 수 있습니다.

   java.lang.IncompatibleClassChangeError의 원인은 무엇입니까?

2. ==============================

   2.JBoss에서이 문제가 발생하면 JBoss가 RESTeasy REST 구현을 기본으로 제공하기 때문에 문제가 발생할 가능성이 큽니다. 독자적인 REST 라이브러리를 EAR / WAR 파일에 패키지하는 경우 배포 된 라이브러리가 작동하도록 기본 RESTeasy를 비활성화해야합니다.
