引言

上一篇讲到了ReentrantLock,在同一个时间点,只能用一个线程能够访问共享资源.今天我们来讲一下读写锁ReadWriteLock,读写锁提供了在同一个时间点,可以有多个线程共享去读取共享资源,当只有有一个线程去写共享资源.

ReadWriteLock主要是Lock锁使用的,提供一个读和一个写的操作.readLock可以在有多个线程同时操作直到没有写的操作.writeLock却在同一个时间点只能有一个线程在操作.
所有ReadWriteLock的实现类必须在writeLock写操作时,保证内存同步,同时还必须和readLock相关联,比如当一个线程获取到读锁时,这必须保证当前线程能在写锁释放后看到所有的更新操作.

例子

首先定一个模拟读写文件的类MockFIle

public class MockFile {// 使用StringBuilder而不是使用StringBuffer// 是因为StringBuilder是线程不安全的,而StringBuffer是线程安全的StringBuilder fileContent;public MockFile() {this.fileContent = new StringBuilder();}public String readFile(){try {Thread.sleep(10);String content = fileContent.toString();Thread.sleep(10);return content;} catch (InterruptedException e) {return null;}}public void writeFile(char content){try {Thread.sleep(10);fileContent.append(content);Thread.sleep(10);} catch (InterruptedException e) {e.printStackTrace();}}
}

注意在该类使用StringBuilder是因为这个类是线程不安全的
StringBuffer是线程安全的

之后编写读文件操作 ReadRunnable

public class ReadRunnable implements Runnable {ReadWriteLock lock;MockFile file;boolean isStop;public ReadRunnable(ReadWriteLock lock, MockFile file) {this.lock = lock;this.file = file;isStop = false;}@Overridepublic void run() {Thread self = Thread.currentThread();while(!isStop){Lock lock = this.lock.readLock();try {lock.lock();String content = file.readFile();System.out.println(self.getName() + " read: " + content);Thread.sleep(10);} catch (InterruptedException e) {e.printStackTrace();}finally {lock.unlock();try {Thread.sleep(50);} catch (InterruptedException e) {e.printStackTrace();}}}}public void setStop() {isStop = true;}
}

然后再编写写文件操作 WriteRunnable

public class WriteRunnable implements Runnable {ReadWriteLock lock;MockFile file;String content;public WriteRunnable(ReadWriteLock lock, MockFile file, String content) {this.lock = lock;this.file = file;this.content = content;}@Overridepublic void run() {Thread self = Thread.currentThread();for (char ch : content.toCharArray()){Lock lock = this.lock.writeLock();try {lock.lock();System.out.println(self.getName() + " write " + ch);file.writeFile(ch);Thread.sleep(20);} catch (InterruptedException e) {e.printStackTrace();} finally {lock.unlock();try {Thread.sleep(200);} catch (InterruptedException e) {e.printStackTrace();}}}}
}

这里需要注意以下几点

读文件操作比写文件操作频繁,这样才能看到边写边读的效果,这就需要在释放锁的时候,让写线程睡久一点,让读线程睡少一点

还有我这里采用判断标记位的方式,让读线程停止操作

最后,我们需要写一个测试类 TestMain

public class TestMain {public static void main(String[] args) {MockFile mockFile = new MockFile();ReentrantReadWriteLock lock = new ReentrantReadWriteLock();Thread thread1 = new Thread(new WriteRunnable(lock, mockFile, "ABCDEFGHIJKLMOOPQRSTUVWXYZ"));Thread thread2 = new Thread(new WriteRunnable(lock, mockFile, "abcdefghijklmoopqrstuvwxyz"));Thread thread3 = new Thread(new WriteRunnable(lock, mockFile, "0123456789"));List<Thread> readThreadList = new ArrayList<>();List<ReadRunnable> readRunnables = new ArrayList<>();for (int i = 0; i < 5; i ++){ReadRunnable readRunnable = new ReadRunnable(lock, mockFile);readThreadList.add(new Thread(readRunnable));readRunnables.add(readRunnable);}thread1.start();thread2.start();thread3.start();for (Thread readThread : readThreadList){readThread.start();}while (thread1.isAlive() || thread2.isAlive() || thread3.isAlive());for (ReadRunnable readRunnable : readRunnables){readRunnable.setStop();}}
}

测试类,需要注意以下几点

创建了三个写操作,
+ 第一个依次写入26个大写字母
+ 第二个依次写入26个小写字母
+ 弟三个依次写入0-9十个数字
创建了五个读操作,让它们不断的读取文件

当全部写操作结束时,这停止这五个读操作

运行程序,结果如下
