NIO管道Pipe

实现开启一条线程向Pipe 管道里面写入数据，另一条线程读取Pipe管道里面的数据

package com.mock;

import org.junit.jupiter.api.Test;

import java.io.IOException;
import java.nio.ByteBuffer;
import java.nio.channels.Pipe;
import java.time.LocalTime;

public class TestPipe {

    @Test
    public void test() throws Exception {
        final Pipe pipe = Pipe.open();
        //一条线程向管道写数据，另一条线程从管道中读取数据
        new Thread(() -> write(pipe)).start();
        new Thread(() -> read(pipe)).start();
        Thread.sleep(6000);
    }

    //写数据到管道
    public void write(Pipe pipe) {
        try {
            ByteBuffer byteBuffer = ByteBuffer.allocate(1024);
            while (true) {
                byteBuffer.put((LocalTime.now() + "你好世界").getBytes());
                byteBuffer.flip();
                pipe.sink().write(byteBuffer);
                Thread.sleep(1000);
                byteBuffer.clear();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    //从管道中读取数据
    public void read(Pipe pipe) {
        ByteBuffer byteBuffer = ByteBuffer.allocate(1024);
        while (true) {
            try {
                int len = pipe.source().read(byteBuffer);
                System.out.println(new String(byteBuffer.array(), 0, len));
                byteBuffer.clear();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}
