java.lang.LinkageError : ClassCastException : 봄 MVC 프로젝트

Question

나는 봄 mvc 및 저지 휴식 클라이언트 프로젝트 1 및 프로젝트 2를 봄 코어로 작업하고 있습니다. Tomcat 서버에서 코드를 실행하는 동안 예외가 발생합니다.

예외 : 잡았다 던질 수는 ClassCastException가 : castjar 시도 : 파일 : /project1/web/webroot/WEB-INF/lib/jersey-core-1.13.jar를 /javax/ws/rs/ext/RuntimeDelegate.classtojar! : file : /project2/lib/jersey-core-1.13.jar! /javax/ws/rs/ext/RuntimeDelegate.class java.lang.LinkageError : ClassCastException : 캐스팅하려고 시도하는 중 : file :/project1/web/webroot/WEB-INF/lib/jersey-core-1.13.jar! /javax/ws/rs/ext/RuntimeDelegate.classtojar:file:/project2/lib/jersey-core-1.13.jar!/javax/ws/rs/ext/RuntimeDelegate.class

Answer 1

당신은 두 프로젝트에서 jersy 존재하는 데. 이렇게하면 jersy 클래스를로드 할 다른 클래스 로더가 생기므로 클래스 캐스트 예외가 발생합니다. jersy가 한 번만로드되었는지 확인하십시오. jersy jar를 서버 라이브러리에 넣고 제공된대로 maven 범위를 사용하면됩니다.
