log4j中的异常深度

Question

我在我的Myfaces 2应用程序中进入实例化异常。 但是通过log4j进行的异常打印正在切断堆栈跟踪的其余部分。 这是我所看到的：

位于org.apache.myfaces.el.unified.resolver.ManagedBeanResolver.createManagedBean（ManagedBeanResolver.java）的org.apache.myfaces.config.ManagedBeanBuilder.buildManagedBean（ManagedBeanBuilder.java:240）中的javax.faces.FacesException：java.lang.InstantiationException ：303）atg.apache.myfaces.el.unified.resolver.ManagedBeanResolver.getValue（ManagedBeanResolver.java:266）at org.apache.myfaces.el的javax.el.CompositeELResolver.getValue（CompositeELResolver.java:54）。在org.apache.myfaces.el.VariableResolverImpl.resolveVariable（VariableResolverImpl.java:65）的org.apache.myfaces.el.convert.VariableResolverToELResolver.getValue（VariableResolverToELResolver。）中的unified.resolver.FacesCompositeELResolver.getValue（FacesCompositeELResolver.java:142）。 java：116）在org.apache.el.parser的org.apache.myfaces.el.unified.resolver.FacesCompositeELResolver.getValue（FacesCompositeELResolver.java:142）的javax.el.CompositeELResolver.getValue（CompositeELResolver.java:54） .AstIdentifier.getValue（AstIdentifier.java:61） org.apache.el.parser.AstValue.getValue（AstValue.java:107）org.apache.el.ValueExpressionImpl.getValue（ValueExpressionImpl.java:186）org.apache.myfaces.view.facelets.el.TagValueExpression .getValue（TagValueExpression.java:85）位于javax.faces.component.UIOutput.getValue（UIOutput.java:71）javax.faces.component._DeltaStateHelper.eval（_DeltaStateHelper.java:243）的javax.faces.component。位于org.apache.myfaces.shared_impl.renderkit.RendererUtils.getObjectValue（RendererUtils.java:238）的javax.faces.component.UISelectBoolean.getValue（UISelectBoolean.java:148）的UIInput.getValue（UIInput.java:143）位于org.apache.myfaces.shared_impl.renderkit.html.HtmlCheckboxRendererBase.encodeEnd（HtmlCheckboxRendererBase.java:79）的.apache.myfaces.shared_impl.renderkit.RendererUtils.getBooleanValue（RendererUtils.java:193）at javax.faces.component.UIComponentBase .encodeEnd（UIComponentBase.java:519）at javax.faces.component.UIComponent.encodeAll（UIComponent.java:626）at javax.faces.component.UIComponent .encodeAll（UIComponent.java:622）位于org.apache.myfaces.view.facelets.FaceletViewDeclarationLanguage.renderView（FaceletViewDeclarationLanguage.java:1320）的javax.faces.component.UIComponent.encodeAll（UIComponent.java:622）。 apache.myfaces.application.ViewHandlerImpl.renderView（ViewHandlerImpl.java:263）位于org.apache.myfaces.tomahawk.application.ResourceViewHandlerWrapper.renderView（ResourceViewHandlerWrapper）的javax.faces.application.ViewHandlerWrapper.renderView（ViewHandlerWrapper.java:59）。 java：93）org.apache.myfaces.lifecycle.RenderResponseExecutor.execute（RenderResponseExecutor.java:85）at org.apache.myfaces.lifecycle.LifecycleImpl.render（LifecycleImpl.java:239）at javax.faces.webapp.FacesServlet .service（FacesServlet.java:191）org.apache.catalina.core.ApplicationFilterChain.internalDoFilter（ApplicationFilterChain.java:290）org.apache.catalina.core.ApplicationFilterChain.doFilter（ApplicationFilterChain.java:206）at org。 apache.myfaces.webapp.filter.ExtensionsFilter.doFi lter（ExtensionsFilter.java:349）org.apache上的org.apache.catalina.core.ApplicationFilterChain.internalDoFilter（ApplicationFilterChain.java:235）org.apache.catalina.core.ApplicationFilterChain.doFilter（ApplicationFilterChain.java:206） org.apache.catalina.core.StandardContextValve.invoke（StandardContextValve.java:191）中的.catalina.core.StandardWrapperValve.invoke（StandardWrapperValve.java:233）位于org.apache.catalina.core.StandardHostValve.invoke（StandardHostValve.java） ：128）org.apache.catalina.valves.ErrorReportValve.invoke（ErrorReportValve.java:102）atg.apache.catalina.core.StandardEngineValve.invoke（StandardEngineValve.java:109）org.apache.catalina.connector。 CoyoteAdapter.service（CoyoteAdapter.java:293）org.apache.jk.server.JkCoyoteHandler.invoke（JkCoyoteHandler.java:190）org.apache.jk.common.HandlerRequest.invoke（HandlerRequest.java:291）at org .apache.jk.common.ChannelSocket.invoke（ChannelSocket.java:769）在org.apache.jk.common.ChannelSocket.processConnection（Chann） elSocket.java:698）org.apache.jk.common.ChannelSocket $ SocketConnection.runIt（ChannelSocket.java:891）at org.apache.tomcat.util.threads.ThreadPool $ ControlRunnable.run（ThreadPool.java:690） at java.lang.Thread.run（Thread.java:619）由java.lang.reflect.Constructor.newInstance（构造函数）中的sun.reflect.InstantiationExceptionConstructorAccessorImpl.newInstance（InstantiationExceptionConstructorAccessorImpl.java:30）引起的java.lang.InstantiationException .java：513）java.lang.Class.newInstance0（Class.java:355）at java.lang.Class.newInstance（Class.java:308）at org.apache.myfaces.config.annotation.TomcatAnnotationLifecycleProvider.newInstance（ TomcatAnnotationLifecycleProvider.java:49）org.apache.myfaces.config.ManagedBeanBuilder.buildManagedBean（ManagedBeanBuilder.java:162）... 48更多

我无法找到更改配置的位置，因此我可以看到“... 48以上”。 有任何想法吗？

Answer 1

你不能。 截断堆栈跟踪是JVM的一个特性，而不是log4j。

它实际上只是丢弃它已经呈现给您的信息。 ... 48 more是the 48 frames that preceded the "Caused by" message的简写。 因此，在您的情况下，省略的48帧是：
