试下 arthas-demo 。 看下 ~/logs/arthas/arthas.log 的内容。 试下启动一个新的进程再来attach。

这是我本地应用启的是sofaweb,attach报错日志 Exception in thread "Attach Listener" java.lang.ClassNotFoundException: com.taobao.arthas.agent.AgentBootstrap at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at com.alipay.sofa.runtime.test.classloader.FwkClassLoader.findClass(FwkClassLoader.java:139) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at sun.instrument.InstrumentationImpl.loadClassAndStartAgent(InstrumentationImpl.java:304) at sun.instrument.InstrumentationImpl.loadClassAndCallAgentmain(InstrumentationImpl.java:411) Agent failed to start!

这个是实现方的FwkClassLoader代码问题，需要处理agent jar。

hengyunabc commented 5 years ago

FwkClassLoader 里的代码没能加载 agent jar里的内容，agent jar是被 system classloader加载的。它没有处理，然后agent加载失败。
