问题描述

我不知道如何解决该问题需要帮助.您的帮助将不胜感激.

我刚刚将log4j2 jars(log4j-api-2.10.0.jar，log4j-core-2.10.0.jar)添加到我的Web应用程序中，并且它开始在我的开发人员中遇到这个问题.后来我添加了log4j-web-2.10.0.jar并尝试了，但仍然失败，并显示相同的消息.

这是我的环境:

IDE: Eclipse Oxygen2
JDK: 1.8.0_162
Jetty (embedded in Eclipse): jetty-9.2.z-SNAPSHOT
OS: Win 10 (64bit)
Framework: GWT 2.8.2

堆栈跟踪(部分):

解决方案

从 https复制://github.com/eclipse/jetty.project/issues/2192 ，(带有其他修改)

这与您使用 JEP-238多次发布JAR 有关. /p>

注意路径.. 

META-INF/versions/9/org/apache/logging/log4j/util/ProcessIdUtil.class

META-INF/versions/<java.specification.version>/*路径前缀告诉您该路径下的类适用于该特定版本的Java，从而替换了顶级JAR中可能相同的命名类.

问题#1797 是首次报告和解决的地方.

它固定用于...

  • jetty-9.3.22.v20171030-2017年10月30日
  • jetty-9.4.8.v20171121-2017年11月21日

由于Jetty 9.2.x寿命已尽，因此不会有任何支持Jetty 9.2.x上的JEP-238的端口.

您的选择是升级到上面列出的受支持版本之一，或者将log4j的版本降级为不使用JEP-238多发行JAR文件的版本.

还要注意，您正在使用的log4j JEP-238多重发布JAR文件也是Java 9 JPMS模块.

存在module-info.class表示这一点.

在问题中，Jetty支持忽略字节码扫描期间的module-info.class. #1692

I need help with an issue I have no idea how to resolve. Your help will be greatly appreciated.

I just added log4j2 jars (log4j-api-2.10.0.jar, log4j-core-2.10.0.jar) to my Web app and it started running into this problem in my dev. Later I added log4j-web-2.10.0.jar and tried, it still fails with the same message.

Here's my environment:

IDE: Eclipse Oxygen2
JDK: 1.8.0_162
Jetty (embedded in Eclipse): jetty-9.2.z-SNAPSHOT
OS: Win 10 (64bit)
Framework: GWT 2.8.2

解决方案

Copied from https://github.com/eclipse/jetty.project/issues/2192, (with additional edits)

This is related to your use of a JEP-238 Multi-Release JAR.

Notice the path ..

META-INF/versions/9/org/apache/logging/log4j/util/ProcessIdUtil.class

The META-INF/versions/<java.specification.version>/* path prefix tells you that the classes below that path are for that specific version of Java, replacing potentially the same named classes in the top level JAR.

Issue #1797 is where this was first reported and fixed.

It was fixed for ...

  • jetty-9.3.22.v20171030 - 30 October 2017
  • jetty-9.4.8.v20171121 - 21 November 2017

Since Jetty 9.2.x is end of life, there will be no backport to support JEP-238 on Jetty 9.2.x.

Your choices are to upgrade to one of the supported versions listed above, or downgrade your version of log4j to one that does not use JEP-238 Multi-Release JAR Files.

Also of note, the log4j JEP-238 Multi-Release JAR file you are using is also a Java 9 JPMS module.

The presence module-info.class indicates that.

Support in Jetty to ignore module-info.class during bytecode scanning was fixed in Issue #1692
