java - WebLogic 版本 12.2.1.1 及更高版本上的 "ClassNotFoundException: org.objectweb.asm.ClassVisitor"(文档 ID 2526226.1)

Question

我正在尝试在web-logic 12c中部署我的遗留应用程序，但问题是每次它都会显示异常，例如>“ClassNotFoundException:org.objectweb.asm.ClassVisitor ，基本上，如果应用程序没有 asm.jar 但在我的应用程序中有 asm.jar 并且我的应用程序成功部署在 web-logic 11< 中，则会出现此问题/强>

经过大量研究，我发现下面的文档中他们说WebLogic 12.2.1 infra 到 WebLogic 12.2.1.3 infra，当使用客户的服务器启动服务器时，无法找到 org.objectweb.asm.ClassVisitorbelow 类已部署应用程序。请有人指导我如何解决此问题

Answer 1

您可以尝试将 asm.jar 添加到应用程序的 WEB-INF/lib 目录中。从错误中可以清楚地看出，JVM 无法找到该类，因此出现 java.lang.ClassNotFoundException
