引言

上一篇講到了ReentrantLock,在同一個時間點,只能用一個線程能夠訪問共享資源.今天我們來講一下讀寫鎖ReadWriteLock,讀寫鎖提供了在同一個時間點,可以有多個線程共享去讀取共享資源,當只有有一個線程去寫共享資源.

ReadWriteLock主要是Lock鎖使用的,提供一個讀和一個寫的操作.readLock可以在有多個線程同時操作直到沒有寫的操作.writeLock卻在同一個時間點只能有一個線程在操作.
所有ReadWriteLock的實現類必須在writeLock寫操作時,保證內存同步,同時還必須和readLock相關聯,比如當一個線程獲取到讀鎖時,這必須保證當前線程能在寫鎖釋放后看到所有的更新操作.

例子

首先定一個模擬讀寫文件的類MockFIle

public class MockFile {

    // 使用StringBuilder而不是使用StringBuffer
    // 是因為StringBuilder是線程不安全的,而StringBuffer是線程安全的
    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();
        }
    }
}

注意在該類使用StringBuilder是因為這個類是線程不安全的
StringBuffer是線程安全的

之后編寫讀文件操作 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;
    }
}

然后再編寫 寫文件操作 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();
                }
            }
        }
    }
}
這里需要注意以下幾點



讀文件操作比寫文件操作頻繁,這樣才能看到邊寫邊讀的效果,這就需要在釋放鎖的時候,讓寫線程睡久一點,讓讀線程睡少一點


還有我這里采用判斷標記位的方式,讓讀線程停止操作

最后,我們需要寫一個測試類 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();
        }
    }
}

測試類,需要注意以下幾點


創建了三個寫操作,


+ 第一個依次寫入26個大寫字母
+ 第二個依次寫入26個小寫字母
+ 弟三個依次寫入0-9十個數字



創建了五個讀操作,讓它們不斷的讀取文件


當全部寫操作結束時,這停止這五個讀操作
