(六)java多线程之ReadWriteLock

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

1. 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

2. 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

1. 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

2. 创建了五个读操作,让它们不断的读取文件

3. 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
