【java】java线程并发测试模版

这里申请了1000个线程，并且执行1000次任务。当所有任务完成后，main退出。

    public class Test {           public static void main(String[] args) {                int count = 1000;                ExecutorService executorService = Executors.newFixedThreadPool(count);                for (int i = 0; i < count; i++)                     executorService.execute(new Test().new Task());                      executorService.shutdown();                while (!executorService.isTerminated()) {                     try {                          Thread.sleep(10);                     } catch (InterruptedException e) {                          e.printStackTrace();                     }                }           }                 public class Task implements Runnable {                      @Override                public void run() {                     try {                          // 测试内容                     } catch (Exception e) {                          e.printStackTrace();                     }                }           }      }

如果要实现真正的并发同时执行，可通过CyclicBarrier来控制。

    public class Test {           public static void main(String[] args) {                int count = 1000;                CyclicBarrier cyclicBarrier = new CyclicBarrier(count);                ExecutorService executorService = Executors.newFixedThreadPool(count);                for (int i = 0; i < count; i++)                     executorService.execute(new Test().new Task(cyclicBarrier));                      executorService.shutdown();                while (!executorService.isTerminated()) {                     try {                          Thread.sleep(10);                     } catch (InterruptedException e) {                          e.printStackTrace();                     }                }           }                 public class Task implements Runnable {                private CyclicBarrier cyclicBarrier;                      public Task(CyclicBarrier cyclicBarrier) {                     this.cyclicBarrier = cyclicBarrier;                }                      @Override                public void run() {                     try {                          // 等待所有任务准备就绪                          cyclicBarrier.await();                          // 测试内容                     } catch (Exception e) {                          e.printStackTrace();                     }                }           }      }
