# 跨线程追踪
- 使用maven或gradle引入toolkit依赖。
<dependency>
<groupId>org.apache.skywalking</groupId>
<artifactId>apm-toolkit-trace</artifactId>
<version>${skywalking.version}</version>
</dependency>
- 用法1
@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());
- 用法2
ExecutorService executorService = Executors.newFixedThreadPool(1);
executorService.submit(CallableWrapper.of(new Callable<String>() {
@Override public String call() throws Exception {
return null;
}
}));
或者
ExecutorService executorService = Executors.newFixedThreadPool(1);
executorService.execute(RunnableWrapper.of(new Runnable() {
@Override public void run() {
//your code
}
}));
- 用法 3.
@TraceCrossThread
public class MySupplier<String> implements Supplier<String> {
@Override
public String get() {
return null;
}
}
CompletableFuture.supplyAsync(new MySupplier<String>());
或者
CompletableFuture.supplyAsync(SupplierWrapper.of(()->{
return "SupplierWrapper";
})).thenAccept(System.out::println);
