spring使用java 8在WebSphere上运行应用程序时出现exception
在WebSphere 9.0 java 8上运行应用程序时，我收到了几个IllegalStateException ， CannotCompileException和LinkageError 。 这是堆栈的错误跟踪：
Caused by: java.lang.IllegalStateException: javassist.CannotCompileException: by java.lang.LinkageError: org.springframework.aop.framework.ProxyCreatorSupport at org.springframework.aop.framework.JavassistApplicationContext.(JavassistApplicationContext.java:61) ... 114 more Caused by: javassist.CannotCompileException: by java.lang.LinkageError: org.springframework.aop.framework.ProxyCreatorSupport at javassist.ClassPool.toClass(ClassPool.java:1120) at javassist.ClassPool.toClass(ClassPool.java:1063) at javassist.ClassPool.toClass(ClassPool.java:1021) at javassist.CtClass.toClass(CtClass.java:1259) at org.springframework.aop.framework.JavassistApplicationContext.(JavassistApplicationContext.java:59) ... 114 more Caused by: java.lang.LinkageError: org.springframework.aop.framework.ProxyCreatorSupport at java.lang.ClassLoader.defineClassImpl(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:346) at java.lang.ClassLoader.defineClass(ClassLoader.java:283) at sun.reflect.GeneratedMethodAccessor17.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:55) at java.lang.reflect.Method.invoke(Method.java:508) at javassist.ClassPool.toClass2(ClassPool.java:1133) at javassist.ClassPool.toClass(ClassPool.java:1114) ... 118 more
而且我得到java.lang.ExceptionInInitializerError ：
com.ibm.ws.webcontainer.webapp.WebApp notifyServletContextCreated SRVE0283E: Exception caught while initializing context: {0} java.lang.ExceptionInInitializerError at java.lang.J9VMInternals.ensureError(J9VMInternals.java:141) at java.lang.J9VMInternals.recordInitializationFailure(J9VMInternals.java:130) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:88) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:57) at java.lang.reflect.Constructor.newInstance(Constructor.java:437) at org.springframework.beans.BeanUtils.instantiateClass(BeanUtils.java:126) at org.springframework.beans.BeanUtils.instantiateClass(BeanUtils.java:104) at org.springframework.web.context.ContextLoader.createWebApplicationContext(ContextLoader.java:258) at org.springframework.web.context.ContextLoader.initWebApplicationContext(ContextLoader.java:204) at org.springframework.web.context.ContextLoaderListener.contextInitialized(ContextLoaderListener.java:47)
在pom.xml文件中，我有以下依赖项。
org.springframework spring-aop ${spring.version} org.springframework spring-beans ${spring.version} org.springframework spring-context ${spring.version} org.springframework spring-context-support ${spring.version} org.springframework spring-core ${spring.version} org.springframework spring-jdbc ${spring.version} org.springframework spring-orm ${spring.version} org.springframework spring-test ${spring.version} test org.springframework spring-tx ${spring.version} org.springframework spring-web ${spring.version} org.springframework spring-webmvc ${spring.version} org.freemarker freemarker 2.3.16 commons-codec commons-codec 1.4 commons-collections commons-collections 3.2.1 provided commons-fileupload commons-fileupload 1.2.2 commons-httpclient commons-httpclient 3.1 commons-io commons-io 1.4 commons-lang commons-lang 2.5 javassist javassist 3.19.0-GA commons-logging commons-logging [1.1.1,) provided commons-logging commons-logging-api [1.0.3,) provided org.slf4j slf4j-api ${slf4jVersion} <!--provided--> org.slf4j jcl-over-slf4j ${slf4jVersion} <!--provided--> org.slf4j slf4j-log4j12 ${slf4jVersion} <!--provided--> log4j log4j 1.2.14 <!--provided--> junit junit ${junit.version} test com.ibm ibmpkcs 8.0 org.apache.maven.plugins maven-compiler-plugin 2.3.2 1.8 1.8 ${maven.compiler.showDeprecation} ${maven.compiler.showWarnings} UTF-8 ${maven.compiler.debug} ${maven.compiler.optimize} 4.2.5.RELEASE 2.4.0.RELEASE 4.0.0.RELEASE 1.6.1 true 4.8.2 3.5.6-Final
我使用的是spring 4.2.5.RELEASE version和javassist 3.19.0-GA版本。
在Web应用程序中，我可以在WebSphere /WEB-INF/lib上安装应用程序后看到以下jar文件
-
aopalliance-1.0.jar -
commons-io-1.4.jar -
jcl-over-slf4j-1.6.1.jar -
spring-aop-4.2.5.RELEASE.jar -

javassist-3.19.0-GA.jar -
slf4j-log4j12-1.6.1.jar -
spring-core-4.2.5.RELEASE.jar
也在web.xml我正在使用org.springframework.aop.framework.JavassistApplicationContext
contextClass org.springframework.aop.framework.JavassistApplicationContext org.springframework.web.context.ContextLoaderListener org.springframework.web.util.Log4jConfigListener
在类路径/ WEB-INF/classes/org/springframework/aop/framework我有一些javassist类。
JavassistAopProxy$1.class JavassistAopProxy$EqualsInterceptor.class JavassistAopProxy$JavassistMethodInvocation.class JavassistAopProxy.class JavassistAopProxy$AdvisedDispatcher.class JavassistAopProxy$ExProxyFactory.class JavassistAopProxy$MethodInterceptor.class JavassistAopProxyFactory.class JavassistAopProxy$CompositeInterceptor.class JavassistAopProxy$FixedChainStaticTargetInterceptor.class JavassistAopProxy$StaticDispatcher.class JavassistApplicationContext.class JavassistAopProxy$DynamicAdvisedInterceptor.class JavassistAopProxy$HashCodeInterceptor.class JavassistAopProxy$UnadvisedInterceptor.class
有关此错误的任何建议吗？ 我试过以下方法
-
class loader父服务器和应用程序上的最后一个方法
-
将spring更新到最新版本
-
从
/WEB-INF/lib路径中删除了javascript jar文件
我无法理解这个错误意味着什么。 任何解释和建议，以解决此错误。 它在WebSphere 6和Java 1.6中运行良好

现在我认为由于javassist文件引起的问题。 我在我的代码中使用javassist加载一个特定的类.org.spring.aop.framework.ProxyCreatorSupport是一个将由类加载器加载的类。 但我得到一些IllegalStateException，当我将.EAR文件部署到WebSphere时无法编译exception。
使用ClassPool.getDefault（），我正在查找系统类路径中的信息。 添加了由转换方法作为参数移交的类加载器。 我已经将类加载器附加到Javassist的搜索路径。
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); } } }
它适用于java 1.6 WebSphere 8。 在更新到Java 8 WebSphere 9之后，我遇到了这些exception。我认为Javassist toClass()在websphere中导致exception。 还有CtClass cc = classPool.get("org.spring.aop.framework.ProxyCreatorSupport"); 提出一些联系问题。 现在有什么建议吗？
