Jedis線程非安全

Jedis是線程不安全

當多個線程操作同一個Jedis Client時候，每次都要掉用connect方法

public void connect() {
        if (!this.isConnected()) {
            try {
                this.socket = new Socket();
                this.socket.setReuseAddress(true);
                this.socket.setKeepAlive(true);
                this.socket.setTcpNoDelay(true);
                this.socket.setSoLinger(true, 0);
                this.socket.connect(new InetSocketAddress(this.host, this.port), this.connectionTimeout);
                this.socket.setSoTimeout(this.soTimeout);
                this.outputStream = new RedisOutputStream(this.socket.getOutputStream());
                this.inputStream = new RedisInputStream(this.socket.getInputStream());
            } catch (IOException var2) {
                this.broken = true;
                throw new JedisConnectionException(var2);
            }
        }

    }

多個線程共用一個socket變量，導致多線程下有可能

線程1:
this.outputStream = new RedisOutputStream(this.socket.getOutputStream());
this.inputStream = new RedisInputStream(this.socket.getInputStream());

線程2:
this.socket = new Socket();
this.socket.setReuseAddress(true);
this.socket.setKeepAlive(true);
this.socket.setTcpNoDelay(true);
this.socket.setSoLinger(true, 0);
this.socket.connect(new InetSocketAddress(this.host, this.port), this.connectionTimeout);
這樣就可能導致sokect的異常關閉
                

其次多線程下共享的outputStream和inputStream流對象也是導致其線程不安全的因素。
