概述

lockInterruptibly()方法比較特殊，當通過這個方法去獲取鎖時，如果其他線程正在等待獲取鎖，則這個線程能夠響應中斷，即中斷線程的等待狀態。也就使說，當兩個線程同時通過lock.lockInterruptibly()想獲取某個鎖時，假若此時線程A獲取到了鎖，而線程B只有等待，那么對線程B調用threadB.interrupt()方法能夠中斷線程B的等待過程。

【注意是：等待的那個線程B可以被中斷，不是正在執行的A線程被中斷】

測試類
package multithreading.lock;import org.junit.Test;public class TestInterruptibly {@Testpublic void testInterruptibly() throws Exception{BussinessClass bc=new BussinessClass();Thread t0=new Thread(){@Overridepublic void run() {bc.bFuction();}};Thread t1=new Thread(){@Overridepublic void run() {bc.bFuction();}};String tName=Thread.currentThread().getName();System.out.println(tName+"-啟動t0！");t0.start();System.out.println(tName+"-我等個5秒，再啟動t1");Thread.sleep(5000);System.out.println(tName+"-啟動t1");t1.start();System.out.println(tName+"-t1獲取不到鎖，t0這貨睡覺了，沒釋放，我等個5秒！");Thread.sleep(5000);System.out.println(tName+"-等了5秒了，不等了，把t1中斷了！");t1.interrupt();Thread.sleep(Long.MAX_VALUE);}}
運行結果
main-啟動t0！
main-我等個5秒，再啟動t1
Thread-0-開始獲取鎖..........
Thread-0-獲取到鎖了！！！！
Thread-0-睡覺了，睡個30秒！
main-啟動t1
main-t1獲取不到鎖，t0這貨睡覺了，沒釋放，我等個5秒！
Thread-1-開始獲取鎖..........
main-等了5秒了，不等了，把t1中斷了！
java.lang.InterruptedException
Thread-1-我好像被中斷了！
