Redis原理

RESP协议

支持tcp协议、基本数据类型，比如数组，字符串等，也可支持其他的通信场景。

模拟redis接收传输过来的set数据

//ServerSocket监听6379端口模拟redis
    public static void jasonWriteSocketServer() {
        ServerSocket serverSocket = null;
        Socket socket = null;
        InputStream inputStream  = null;
        try {
            serverSocket = new ServerSocket(6379);
            socket = serverSocket.accept();
            inputStream = socket.getInputStream();
            byte[] b = new byte[64];
            inputStream.read(b);
            System.out.println("jasonWriteSocketServer receive msg: "+new String(b));
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }finally {
            try {
                serverSocket.close();
                socket.close();
                inputStream.close();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        }
    }
    

//正常的setString
    public static void setString() {
        Jedis jedis = new Jedis();
        System.out.println("redis is connect success!");
        jedis.set("name", "james");
        System.out.println("address is setting success!");
        jedis.close();
    }
    

测试结果
