java - [Azure][适用于 Java 的 Application Insights 代理]java.lang.NoClassDefFoundError : http/RequestLine

Question

使用 applicationinsights-agent-1.0.6.jar 作为代理启动 Jetty 后(请参阅 https://github.com/Azure/azure-content/blob/master/articles/application-insights/app-insights-java-agent.md )，我得到以下堆栈跟踪。删除代理并删除堆栈跟踪。

我不明白为什么它会遇到“java.lang.NoClassDefFoundError: http/RequestLine”，我找不到这个类......

有人有同样的问题吗？

命令行

    java -Djetty.home=/opt/servers/jetty -Djetty.base=/opt/servers/jetty-base  -Djava.awt.headless=true -Dfile.encoding=UTF-8  -javaagent:/opt/servers/jetty-base/lib/ext/applicationinsights-agent-1.0.6.jar -Djava.net.preferIPv4Stack=true -cp /opt/servers/jetty/start.jar org.eclipse.jetty.start.Main &

Answer 1

根据异常java.lang.NoClassDefFoundError ，这意味着命令行中缺少一些依赖库，例如 httpclient。

要解决这个问题，您需要下载zip file来自 page 的 Application Insights SDK for Java ，并将它们与 : 分隔符附加到选项 -cp 的尾部。
