跨线程追踪

• 使用 maven 和 gradle 依赖相应的工具包

   <dependency>
      <groupId>org.apache.skywalking</groupId>
      <artifactId>apm-toolkit-trace</artifactId>
      <version>${skywalking.version}</version>
   </dependency>

• 使用方式一.

    @TraceCrossThread
    public static class MyCallable<String> implements Callable<String> {
        @Override
        public String call() throws Exception {
            return null;
        }
    }
...
    ExecutorService executorService = Executors.newFixedThreadPool(1);
    executorService.submit(new MyCallable());

• 使用方式二.

    ExecutorService executorService = Executors.newFixedThreadPool(1);
    executorService.submit(CallableWrapper.of(new Callable<String>() {
        @Override public String call() throws Exception {
            return null;
        }
    }));
