如何正確的使用ThreadPoolExecutor線程池,相信很多沒有經驗的人對此束手無策,為此本文總結了問題出現的原因和解決方法,通過這篇文章希望你能解決這個問題。
import java.util.Random;
import java.util.concurrent.*;
public class PoolTest {
private BlockingQueue<Runnable> workingQueue = new ArrayBlockingQueue<Runnable>(10);
private RejectedExecutionHandler rejectedExecutionHandler = new ThreadPoolExecutor.CallerRunsPolicy();
private ExecutorService threadPool = new ThreadPoolExecutor(10, 10, 0L, TimeUnit.MILLISECONDS, workingQueue, rejectedExecutionHandler);
private Random random = new Random();
public void test() {
int size = 10;
final CountDownLatch latch = new CountDownLatch(size);
for(int i = 0; i < size; i ++) {
threadPool.execute(new Runnable() {
int x = random.nextInt(10);
@Override
public void run() {
try {
plus(x,x);
} finally {
latch.countDown();
}
}
});
}
try {
latch.await();
} catch (InterruptedException e) {
e.printStackTrace();
} finally {
System.out.println("線程全部執行完成");
}
threadPool.shutdown();
}
public void plus(int x, int y) {
System.out.println("sum = " + (x + y));
}
public static void main(String[] args) {
PoolTest poolTest = new PoolTest();
poolTest.test();
}
}
