基于netty,zookeeper开发的RPC框架,NIO设计

• 使用zookeeper服务发现
• 使用长连接TCP池,netty作为网络IO,支持全双工通信
• 消息发送支持异步/同步,NIO
• 自动选择符合action节点服务器,支持权重分发消息
• 欢迎学习交流~

  

Demo

Node

    //open node server 1
    NodeInfo nodeInfo = NodeRegistry.buildNode();//read application.properties
    //sync callback
    NodeLauncher.start(nodeInfo, new MessageListener() {
        @Override
        public byte[] onMessage(Async async, byte[] message) {
        return ("Hello! node1 callback -" + new String(message)).getBytes();
        }
    });

    //open node server 2
    NodeInfo nodeInfo2 = new NodeInfo();
    nodeInfo2.setZkIps("127.0.0.1:2181");
    nodeInfo2.setZkPath("/qsrpc");
    nodeInfo2.setAction("order");
    nodeInfo2.setIp("127.0.0.1");
    nodeInfo2.setPort(8848);
    nodeInfo2.setWeight(2);

    //async callback
    NodeLauncher.start(nodeInfo2, new MessageListener() {
        @Override
        public byte[] onMessage(final Async async, final byte[] message) {
        new Thread(new Runnable() {
            @Override
            public void run() {
            async.callBack(("Hello! node2 callback -" + new String(message)).getBytes());
            }
        }).start();
        return null;
        }
    });

Client

    //async
    for (int i = 0; i < 9; i++) {
        RPCClientManager.getInstance().sendAsync("user", "user".getBytes(),
            new Callback<byte[]>() {
            @Override
            public void handleResult(byte[] result) {
                System.out.println("send [user] Result: " + new String(result));
            }

            @Override
            public void handleError(Throwable error) {
                error.printStackTrace();
            }
            });
    }
    System.out.println("send [user] Done");

    //sync
    for (int i = 0; i < 9; i++) {
        Thread.sleep(1000);
        byte[] msg_cb = RPCClientManager.getInstance().sendSync("order", "order".getBytes());
        System.out.println("send [order] Result: " + new String(msg_cb));
    }
    System.out.println("send [order] Done");
