4 years ago 你好，根据你给的 JVM 启动参数，你应该是把 MyPerf4J-ASM.jar 打到 tomcat 的 war 包里了，这样可能会存在同一个类被不同的 ClassLoader 多次加载的问题，你不要把 MyPerf4J-ASM.jar 打到 tomcat 的 war 包里，然后再次启动应该就好了。

问题描述 加载模块正常，但是所有的方法都无法记录，并且在日志中报错：
[MyPerf4J] WARN [pool-860-thread-4] ProfilingAspect.profiling(): methodTagId=668, methodTag=null, startNanos: 16906482417446846, IGNORED!!!
如下代码是已经被执行了
但是在执行这个的时候 ，就还是会是false，所以return
