正常來說Thread對(duì)象的setName方法就應(yīng)該生效。

這個(gè)需要分析代碼了。把你的代碼提出來吧。

public class TestThread {

public static void main(String[] args) {

ExecutorService service = Executors.newFixedThreadPool(2);

RunnableTest rt = new RunnableTest();

Thread t1 = new Thread(rt, "t1");

Thread t2 = new Thread(new RunnableTest(), "t2");

service.execute(t1);

service.execute(t2);

}

}

class RunnableTest implements Runnable {

public void run() {

for (int i = 0; i <= 20; i++) {

// 得到當(dāng)前線程的名字

String str = Thread.currentThread().getName();

System.out.println(str + ":" + i);

}

}

}
