import java.io.InputStream;
import java.util.concurrent.ConcurrentLinkedDeque;

4. 自定义控制
package com.learning;

import java.util.concurrent.atomic.AtomicBoolean;
import java.util.concurrent.locks.Condition;
import java.util.concurrent.locks.Lock;  
import java.util.concurrent.locks.ReentrantLock;  
  
public class ManualResetEvent {  
    private final Lock lock = new ReentrantLock();  
    private final Condition condition = lock.newCondition();  
    private AtomicBoolean isSet = new AtomicBoolean(false);
  
    public void set() {  
        lock.lock();  
        try {  
            isSet.set(true);  
            // 唤醒所有等待的线程  
            condition.signalAll();  
        } finally {  
            lock.unlock();  
        }  
    }  
  
    public void reset() {  
        lock.lock();  
        try {  
            isSet.set(false);  
            // 注意：我们在这里不唤醒任何线程，因为它们是等待信号被设置  
        } finally {  
            lock.unlock();  
        }  
    }  
  
    public void waitForever() throws InterruptedException {  
        lock.lock();  
        try {  
            while (!isSet.get()) {  
                // 等待信号被设置  
                condition.await();  
            }  
        } finally {  
            lock.unlock();  
        }  
    }  
  
    // 也可以提供一个带有超时的等待方法  
    public boolean waitFor(long timeout, TimeUnit unit) throws InterruptedException {
        lock.lock();  
        try {  
            if (!isSet.get()) {  
                return condition.await(timeout, unit);  
            }  
            return true;  
        } finally {  
            lock.unlock();  
        }  
    }  
  
    // 注意：这里没有包含TimeUnit的导入，你需要添加它  
    // import java.util.concurrent.TimeUnit;  
  
    // 示例用法  
    public static void main(String[] args) throws InterruptedException {  
        ManualResetEvent event = new ManualResetEvent();  
  
        // 启动一个线程来模拟生产者设置事件  
        new Thread(() -> {  
            try {  
                Thread.sleep(1000); // 模拟耗时操作  
                event.set(); // 设置事件，允许等待的线程继续执行  
                Thread.sleep(1000); // 再次模拟耗时操作  
                event.reset(); // 重置事件，使等待的线程再次等待  
            } catch (InterruptedException e) {  
                e.printStackTrace();  
            }  
        }).start();  
  
        // 主线程等待事件被设置
        // 等待事件被设置
        event.waitForever();

        // 在这里可以添加更多的逻辑来处理事件被重置的情况  
        // 例如，通过循环等待事件再次被设置  
        // 注意：在实际应用中，你可能需要处理更多的线程和更复杂的逻辑
    }

    public void close() {
        try {
            isSet.set(false);
            // 唤醒所有等待的线程
            condition.signalAll();
        } finally {
            lock.unlock();
        }
    }
}
5. 自定义语音流
package com.xiaoi.xics.avatar.api.interfaces;
 
import com.microsoft.cognitiveservices.speech.audio.PullAudioInputStreamCallback;
import lombok.extern.slf4j.Slf4j;
import java.io.IOException;
import java.io.InputStream;

/**
 * 自定义语音流
 */
@Slf4j
public class VoiceAudioStream extends PullAudioInputStreamCallback {
 
    private EchoStream dataStream = new EchoStream();
    private ManualResetEvent waitForEmptyDataStream = null;
    private InputStream stream;

    /**
     * 服务从PullAudioInputStream中读取数据, 读到0个字节并不会关闭流
     */
    @Override
    public int read(byte[] dataBuffer){
        long  ret = 0;
        // 用户主动close时可以关闭流
        if (waitForEmptyDataStream != null && !dataStream.dataAvailable()){
            waitForEmptyDataStream.set();
            return 0;
        }
        try {
            if(this.stream != null){
                ret = this.stream.read(dataBuffer,0, dataBuffer.length);
                if((int)ret < 1){
                    this.stream = dataStream.Read(dataBuffer, 0, dataBuffer.length);
                    ret = this.stream.read(dataBuffer,0, dataBuffer.length);
                }
            }else{
                this.stream = dataStream.Read(dataBuffer, 0, dataBuffer.length);
                ret = this.stream.read(dataBuffer,0, dataBuffer.length);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return (int)Math.max(0, ret);
    }

    /**
     * Client向PullAudioInputStream写入数据
     */
    public void write(byte[] buffer, int offset, int count){
        dataStream.write(buffer, offset, count);
    }
 
    @Override
    public void close(){
        if (dataStream.dataAvailable()){
            // 通过ManualResetEvent强制流的使用者必须调用close来手动关闭流
            waitForEmptyDataStream = new ManualResetEvent();
            try {
                waitForEmptyDataStream.waitForever();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
        if(waitForEmptyDataStream != null){
            this.waitForEmptyDataStream.close();
        }
        try {
            this.dataStream.close();
            this.stream.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
6. 说明
  • 1.学习用途，切勿放入工作当中，警惕线程控制类。
  • 2.springboot集成websocket流程省略，前端连上websocket后打开麦克风传入语音输入流。
  • 3.亲测有效。自测参考地址：ws://127.0.0.1:8080/microsoft
  • 4.参考C#的实现过程的，点我跳转。
