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;
    }

    @Override
    public 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;
    }

    @Override
    public 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 readThreadList = new ArrayList<>();
        List 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

通过运行结果,我们可以发现,读写操作是互不干扰的.每次写操作释放完锁,读操作都可以把之前写的数据全部读取出来.
