ganpengyu opened a new issue #3154: Why the plugin do not generate a traceid URL: https://github.com/apache/skywalking/issues/3154 - Why do you submit this issue? - Question or discussion ___ ### Question - What do you want to know? I try to enhance my custom class as below: ```java public abstract class TopJobHandler extends IJobHandler { @Override public ReturnT<String> execute(String s) throws Exception { ReturnT<String> result = run(s); return result; } public abstract ReturnT<String> run(String s) throws Exception; } ``` My every job should extends TopJobHandler，Usage Example: ```java @Component @Slf4j @JobHandler(value = "mockJobHandler") public class MockJobHandler extends TopJobHandler { @Autowired private MockService mockService; @Override public ReturnT<String> run(String s) throws Exception { for (int i = 0; i < 5; i++) { log.info("任务被执行，输出：{}", mockService.mock()); } return ReturnT.SUCCESS; } } ``` So I add a plugin to enhance it. ```java public class XxlJobExecutorInstrumentation extends ClassInstanceMethodsEnhancePluginDefine { private static final String ENHANCE_CLASS = "com.ganpengyu.mock.xxljobtracemock.config.TopJobHandler"; private static final String JOB_EXECUTOR_INTERCEPTOR_CLASS = "org.apache.skywalking.apm.plugin.xxljob.XxlJobExecutorInterceptor"; @Override protected ConstructorInterceptPoint[] getConstructorsInterceptPoints() { return new ConstructorInterceptPoint[0]; } @Override protected InstanceMethodsInterceptPoint[] getInstanceMethodsInterceptPoints() { return new InstanceMethodsInterceptPoint[]{ new InstanceMethodsInterceptPoint() { @Override public ElementMatcher<MethodDescription> getMethodsMatcher() { return named("execute"); } @Override public String getMethodsInterceptor() { return JOB_EXECUTOR_INTERCEPTOR_CLASS; } @Override public boolean isOverrideArgs() { return false; } } }; } @Override protected ClassMatch enhanceClass() { return byName(ENHANCE_CLASS); } } ``` Then I write an interceptor as below ( beforeMethod()) ```java @Override public void beforeMethod(EnhancedInstance objInst, Method method, Object[] allArguments, Class<?>[] argumentsTypes, MethodInterceptResult result) throws Throwable { String param = (String) allArguments[0]; LOGGER.info("Executor param is {}", param); final ContextCarrier contextCarrier = new ContextCarrier(); AbstractSpan span = ContextManager.createEntrySpan("executor_instance_name", contextCarrier); span.tag("execute_param", param); span.setComponent(ComponentsDefine.XXL_JOB); } ``` Now my question is the log in my example codes printed without traceId, ``` [TID: N/A] 10:39:48.202 logback [Thread-27] INFO c.g.m.x.job.MockJobHandler - 任务被执行，输出：Hello XXL JOB ``` Plugin Interceptor is work well, but do not generate traceId. So, how should I do to solve it. Thk!
