ARTIFACTORY:如何排除NoClassDefFound错误?
2023-01-22十一10
描述
日志中可能会出现如下错误。
2021-07-19 t9:22:10. 832z [jfac] [ERROR] [4f658ce7fcdb7a11] [.s.b.w.s.s。ErrorPageFilter:186] [27.0.0.1-8040-exec-2] -从请求[/api/v1/registry/join/router]中转发到错误页面，原因是异常[org.glassfish.jersey.server. server. request [/api/v1/registry/join/router]。ContainerException: java.lang. noclassdeffounderror: java/security/interfaces/RSAPrivateKey]
javax.servlet.ServletException: org.glassfish.jersey.server.ContainerException: java.lang. noclassdeffounderror: java/security/interfaces/RSAPrivateKey
决议
要查看相关的类是如何被加载到Artifactory的JVM中的，需要检查Java类日志记录(它跟踪类的加载和卸载)以进行进一步诊断。
对于Artifactory 7.x:
在系统的extraJavaOpts中增加" -verbose:class "。yaml文件。如。
extraJavaOpts: "-server -Xms512m -Xmx2g -Xss256k -XX:+UseG1GC -verbose:class"

对于Artifactory 6.x:
修改$ARTIFACTORY_HOME/bin/artifactory.default文件中的JAVA_OPTIONS，或如下所示:设置JVM参数．如。
export JAVA_OPTIONS="-server -Xms512m -Xmx4g -Xss256k -XX:+UseG1GC -XX:OnOutOfMemoryError="kill - 9% p" -verbose:class"

- 如果没有从类的预期位置加载任何东西，请查看Java CLASSPATH并确保它是其中的一部分。
- 如果某些类是从该位置加载的，那么可能是另一个包含该类的JAR文件丢失了。在Javadocs中查看问题类。
注意:问题解决后，关闭详细日志记录，因为它会影响应用程序的性能。
