说明

代码里只触发了retransformClasses：

	public static void reTransform(Instrumentation instrumentation) throws UnmodifiableClassException {
		ClassFileTransformer transformer = new ClassFileTransformer() {
			@Override
			public byte[] transform(ClassLoader loader, String className, Class<?> classBeingRedefined,
					ProtectionDomain protectionDomain, byte[] classfileBuffer) throws IllegalClassFormatException {
				return null;
			}
		};
		try {
			instrumentation.addTransformer(transformer, true);

			try {
				instrumentation.retransformClasses(TestController.class);
			} catch (Throwable e) {
				e.printStackTrace();
			}

		} finally {
			instrumentation.removeTransformer(transformer);
		}

	}

无agent时运行结果

before =============
com.example.demo.TestController
after =============
com.example.demo.TestController

配置 apache-skywalking-apm-7.0.0.tar.gz agent时

-javaagent:/apache-skywalking-apm-bin/agent/skywalking-agent.jar
