[SPRING] Java 8로 WebSphere에서 애플리케이션을 실행할 때 봄 예외

SPRING

Java 8로 WebSphere에서 애플리케이션을 실행할 때 봄 예외

WebSphere 9.0 Java 8에서 실행되는 응용 프로그램이 실행될 때 여러 개의 IllegalStateException, CannotCompileException 및 LinkageError가 발생했습니다. 이것은 스택 추적 오류입니다.

Caused by: java.lang.IllegalStateException: javassist.CannotCompileException: by java.lang.LinkageError: org.springframework.aop.framework.ProxyCreatorSupport

또한 java.lang.ExceptionInInitializerError 가져 오는 중 :

나는 봄 4.2.5.RELEASE 버전과 javassist 3.19.0-GA 버전을 사용하고있다.

웹 응용 프로그램에서는 WebSphere / WEB-INF / lib에 응용 프로그램을 설치 한 후 다음 jar 파일을 볼 수 있습니다

또한 web.xml에서 org.springframework.aop.framework.JavassistApplicationContext를 사용하고 있습니다.

<context-param>
        <param-name>contextClass</param-name>
        <param-value>org.springframework.aop.framework.JavassistApplicationContext</param-value>

<listener>
 <listenerclass>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

클래스 경로 / WEB-INF / classes / org / springframework / aop / framework에는 javassist 클래스가 있습니다.

JavassistAopProxy$1.class

JavassistAopProxy$UnadvisedInterceptor.class

이 오류에 대한 제안 사항이 있으십니까? 나는 다음과 같은 방법을 시도했다.

나는이 오류의 의미를 이해할 수 없다. 이 오류를 해결하기위한 설명과 제안. Java 1.6에서 WebSphere 6에서 정상적으로 작동했습니다.

최신 정보

그리고 지금은 문제가 javassist 파일로 인해 생각합니다. 내 코드에서 javassist를 사용하여 특정 클래스를로드 중입니다. org.spring.aop.framework.ProxyCreatorSupport는 클래스 로더에 의해로드 될 클래스입니다. 하지만 일부 IllegalStateException지고, 내가 WebSphere에 .EAR 파일을 배포 할 때 예외를 컴파일 할 수 없습니다.

ClassPool.getDefault ()를 사용하여 시스템 클래스 경로에서 정보를 찾고 있습니다. 변환 메소드에 의해 인수로서 건네받은 클래스 로더를 추가했습니다. Javassist의 검색 경로에 클래스 로더를 추가했습니다.

package org.spring.aop.framework;

import javassist.ClassPool;
import javassist.CtClass;
import javassist.CtConstructor;
import javassist.LoaderClassPath;
import org.springframework.web.context.support.XmlWebApplicationContext;

public class JavassistApplicationContext extends XmlWebApplicationContext {

    static {
        ClassPool classPool = ClassPool.getDefault();
        try {
            ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
            classPool.appendClassPath(new LoaderClassPath(classLoader));

            CtClass cc = classPool.get("org.spring.aop.framework.ProxyCreatorSupport");
            CtConstructor c = cc.getConstructors()[0];
            c.insertAfter("$0.aopProxyFactory = new org.spring.aop.framework.JavassistAopProxyFactory();");
            cc.toClass();
        } catch (Exception e) {
            throw new IllegalStateException(e);
        }
    }
}

Java 1.6 WebSphere 8에서 제대로 작동했습니다. 자바 8 웹 스피어 9 업데이트 후 이러한 종류의 예외가 발생합니다 .Javassist toClass () websphere에서 예외를 일으키는 것 같아요. 또한 CtClass cc = classPool.get ( "org.spring.aop.framework.ProxyCreatorSupport"); 일부 연결 문제가 발생합니다. 어떤 제안이라도?
