Question

我最近在WebSphere上部署应用程序时看到了这一点。

  W com.ibm.ws.ecs.internal.scan.context.impl.ScannerContextImpl scanJAR unable to open input stream for resource module-info.class in archive WEB-INF/lib/stax-ex-1.8.jar

当我在Tomcat上部署相同的WAR时，它可以工作。我正在使用JDK 1.7.80。其他人看到了吗？如果是这样，解决办法是什么？

谢谢。

Answer 1

module-info文件是Java 9中新引入的。为了了解新的module-info类文件，需要更新字节码扫描库（例如ASM），否则它们将遇到此异常。由于您是在Java 7上运行，因此module-info.class文件没有任何作用（除了引起ASM崩溃）。

您的选择似乎是：

将ASM更新为支持Java 9的版本，该版本为ASM 6.0或更高版本
请勿在您的应用程序中打包包含module-info.class的库，例如stax-ex-1.8.jar。
从诸如module-info.class之类的库中删除stax-ex-1.8.jar个文件，以使ASM之类的字节码扫描工具在看到它们时不会崩溃。

打开资源模块-info.class的输入流时出错
