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

Question

使用 applicationinsights-agent-1.0.6.jar 作为代理启动我的码头后（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。删除代理删除堆栈跟踪。

我不明白为什么它会打扰“java.lang.NoClassDefFoundError: http/RequestLine”，我发现这个类无处...

有人有同样的问题吗？

根据异常java.lang.NoClassDefFoundError，表示在命令行中遗漏了一些依赖库，如httpclient。

要解决此问题，您需要从page 下载Application Insights SDK for Java 的zip file，并将: 分隔符附加到选项-cp 的尾部。

如有任何疑问，请随时告诉我。
