一、客户端设计
🍅 1、设计三个核心类
三个核心类:
(1)ConnectoonFactory连接工厂:这个类,持有服务器的地址,主要功能是创建出连接Connectiond对象
(2)Connection:表示一个TCP连接,持有Socket对象,写入请求/读取响应,管理多个Channel对象
(3)Channel:表示一个逻辑上的连接。当前设定的交互模型,一个TCP连接是可以进行复用的,一个客户端可以有多个模块,每个模块都可以和brokerServer之间建立“逻辑上的连接”(channel),但是这几个模块的channel之间是互相不影响的。同时还需要提供一系列的方法,与服务器提供的核心API进行对应。
先创建这三个核心的类
在包mqclient中创建这三个类。
@Data
public class ConnectionFactory {
// BrokerServer的ip地址
private String host;
// BrokerServer端口号
private int port;
public Connection newConnection(){
Connection connection = new Connection(host,port);
return connection;
}
}
@Data
public class Connection {
private Socket socket = null;
// 需要管理多个channel,使用哈希表把若干个channel组织起来
private ConcurrentHashMap<String ,Channel> channelMap = new ConcurrentHashMap<>();
private InputStream inputStream;
private OutputStream outputStream;
private DataInputStream dataInputStream;
private DataOutputStream dataOutputStream;
private ExecutorService callbackPool = null;
public Connection(String host,int port) throws IOException {
socket = new Socket(host,port);
inputStream = socket.getInputStream();
outputStream = socket.getOutputStream();
dataInputStream = new DataInputStream(inputStream);
dataOutputStream = new DataOutputStream(outputStream);
}
// 使用该方法分别处理,当前响应是一个针对控制请求的响应,还是服务器推送的响应
private void dispatchResponse(Response response) throws IOException, ClassNotFoundException, MqException {
//TODO
}
// 发送请求
public void writeRequest(Request request) throws IOException {
// TODO
}
// 读取响应
public Response readResponse() throws IOException {
// TODO
}
// 通过这个方法,再connection中创建出一个channel
public Channel createChannel(){
// TODO
return channel;
}
// 关闭connection
public void close() {
//TODO
}
}
@Data
public class Channel {
private String channelId;
// 当前channel属于哪个连接
private Connection connection;
// 用来存储后续客户端收到的服务器的响应
private ConcurrentHashMap<String, BasicReturns> basicReturnsMap = new ConcurrentHashMap<>();
// 如果当前的Channel订阅了某个队列,此处就需要记录对应的回调是什么
// 当该队列的消息返回回来的时候,就调用回调
// 约定一个channel值能有一个回调
private Consumer consumer = null;
public Channel(String channelId, Connection connection) {
this.channelId = channelId;
this.connection = connection;
}
// 这个方法主要和服务器进行交互,
// 目的是为了告知服务器,此处客户端创建了新的channel
public boolean createChannel() {
// TODO
return true;
}
// 使用该方法阻塞等待服务器的响应
private BasicReturns waitResult(String rid) {
return null;
}
// 关闭channel,给服务器发送一个type == 0x2的请求
public boolean close() throws IOException {
//TODO
return null;
}
//创建核心的API方法
}
🍅 2、完善Connection类
这里完成发送请求、读取响应、创建channel、处理响应、关闭连接
🎄 读取请求和响应、创建channel
// 发送请求
public void writeRequest(Request request) throws IOException {
dataOutputStream.writeInt(request.getType());
dataOutputStream.writeInt(request.getLength());
dataOutputStream.write(request.getPayload());
dataOutputStream.flush();
System.out.println("[Connection] 发送请求! type=" + request.getType() + ", length=" + request.getLength());
}
// 读取响应
public Response readResponse() throws IOException {
Response response = new Response();
response.setType(dataInputStream.readInt());
response.setLength(dataInputStream.readInt());
byte[] payload = new byte[response.getLength()];
int n = dataInputStream.read(payload);
if (n != response.getLength()) {
throw new IOException("读取的响应数据不完整!");
}
response.setPayload(payload);
System.out.println("[Connection] 收到响应! type=" + response.getType() + ", length=" + response.getLength());
return response;
}
// 通过这个方法,再connection中创建出一个channel
// 此处的createChannel()方法在后面channel类中编写以后,会抛异常,这里大家写完channel之后回过来手动抛一下
public Channel createChannel() { //throws IOException
String channelId = "C-" + UUID.randomUUID();
Channel channel = new Channel(channelId,this);
// 把channel对象放到Connection管理的channel的哈希表中
channelMap.put(channelId,channel);
// 同时也需要把“创建channel”的这个消息也告诉服务器
boolean ok = channel.createChannel();
if (!ok){
// 创建channel失败
// 删除hash表中的键值对
channelMap.remove(channelId);
return null;
}
return channel;
}
🎄 添加扫描线程
在构造方法中,添加一个扫描线程,使用该线程,不停的从socket中读取响应,再将这个响应交给对应的channnel。
public Connection(String host,int port) throws IOException {
socket = new Socket(host,port);
inputStream = socket.getInputStream();
outputStream = socket.getOutputStream();
dataInputStream = new DataInputStream(inputStream);
dataOutputStream = new DataOutputStream(outputStream);
callbackPool = Executors.newFixedThreadPool(4);
// 创建一个扫描线程
// 该线程负责不停的从socket中读取响应数据,然后把这个响应数据再交给对应的channel负责处理
Thread t = new Thread(() -> {
try {
while (!socket.isClosed()) {
Response response = readResponse();
dispatchResponse(response);
}
} catch (SocketException e) {
// 连接正常断开的. 此时这个异常直接忽略.
System.out.println("[Connection] 连接正常断开!");
} catch (IOException | ClassNotFoundException | MqException e) {
System.out.println("[Connection] 连接异常断开!");
e.printStackTrace();
}
});
t.start();
}
🎄 处理不同的响应
使用该方法分别处理两种不同的响应,当前响应是一个针对控制请求的响应,还是服务器推送的响应。
private void dispatchResponse(Response response) throws IOException, ClassNotFoundException, MqException {
if (response.getType() == 0xc) {
// 服务器推送来的消息数据
SubScribeReturns subScribeReturns = (SubScribeReturns) BinaryTool.fromBytes(response.getPayload());
// 根据channelId找到对用的channel对象
Channel channel = channelMap.get(subScribeReturns.getChannelId());
if (channel == null) {
throw new MqException("[Connection] 该消息对应的 channel 在客户端中不存在! channelId =" + channel.getChannelId());
}
callbackPool.submit(() -> {
try {
channel.getConsumer().handleDelivery(subScribeReturns.getConsumerTag(), subScribeReturns.getBasicProperties(),
subScribeReturns.getBody());
} catch (MqException | IOException e) {
e.printStackTrace();
}
});
} else {
// 当前响应是针对控制请求的响应
BasicReturns basicReturns = (BasicReturns) BinaryTool.fromBytes(response.getPayload());
// 把这个结果放到对应的channel的hash表中
Channel channel = channelMap.get(basicReturns.getChannelId());
if (channel == null) {
throw new MqException("[Connection] 该消息对应的 channel 在客户端中不存在! channelId =" + channel.getChannelId());
}
channel.putReturns(basicReturns);
}
}
🎄 关闭连接
public void close() {
// 关闭connection,释放持有的资源
try {
callbackPool.shutdownNow();
channelMap.clear();
inputStream.close();
outputStream.close();
socket.close();
} catch (IOException e) {
e.printStackTrace();
}
}
🍅 3、完善Channel类
🎄 编写createChannel()
// 这个方法主要和服务器进行交互,
// 目的是为了告知服务器,此处客户端创建了新的channel
// 这个方法主要和服务器进行交互,
// 目的是为了告知服务器,此处客户端创建了新的channel
public boolean createChannel() throws IOException {
// 对于创建channel来说,payload就是一个basicArguments
BasicArguments basicArguments= new BasicArguments();
basicArguments.setChannelId(channelId);
// rid表示这次请求的id
basicArguments.setRid(generateRid());
byte[] payload = BinaryTool.toBytes(basicArguments);
Request request = new Request();
request.setType(0x1);
request.setLength(payload.length);
request.setPayload(payload);
// 发送构造出的请求
connection.writeRequest(request);
// 等待服务器的响应
BasicReturns basicReturns = waitResult(basicArguments.getRid());
return basicReturns.isOk();
}
private String generateRid(){
return "R-" + UUID.randomUUID().toString();
}
🎄 编写waitResult()和putRetuens()方法
putRetuents()是为了将返回的响应放到对用的哈希表中
public void putReturns(BasicReturns basicReturns) {
basicReturnsMap.put(basicReturns.getRid(),basicReturns);
synchronized (this){
// 当前不知道有多少个线程在等待上面的响应
// 把多有的等待的线程都唤醒
notifyAll();
}
}
waitResult()方法的作用是为了阻塞等待服务器的响应。以下举例说明:
如下,假如有3个channel,按照123的顺序发送了请求,所以应该是请求1先等待响应1,然后再是2和3。
但是,现在有一个情况,服务器这边是多线程并发处理请求,服务器处理每个请求的时间不一样,返回响应的顺序也就不一样。
如下图,channel1等待的是响应1,但是先返回的响应却是2和3。响应1还没来,请求1就一直等。请求1,没等到,后面的2和3也就拿不到响应
所以,为了解决这个问题,就创建了basicReturnsMap,将socket中收到的所有响应数据放到这个在前面创建的basicReturnsMap哈希表中。客户端的的请求,就可以不断的从这个哈希表中寻找是否存在和自己匹配的响应。
如果存在,就把相应取走;不存在,就继续等待。
这个waitResult()方法就是,当请求对应的响应不再哈希表中时,就阻塞等待。
// 使用该方法阻塞等待服务器的响应
private BasicReturns waitResult(String rid) {
BasicReturns basicReturns = null;
while ((basicReturns = basicReturnsMap.get(rid)) == null){
// 如果查询结果为null,说明响应没来
// 此时就需要阻塞等待
// 此处加锁是为了保证wait/notify的是同一个对象
synchronized (this){
try {
wait();
}catch (InterruptedException e){
e.printStackTrace();
}
}
}
// 读取成功之后,把这个响应从哈希表中删除掉
basicReturnsMap.remove(rid);
return basicReturns;
}
🎄 编写其他核心API

二、客户端测试

TigerMqApplication.context = SpringApplication.run(TigerMqApplication.class);
brokerServer = new BrokerServer(9090);
t = new Thread(() -> {
// 这个 start 方法会进入一个死循环. 使用一个新的线程来运行 start 即可!
try {
brokerServer.start();
} catch (IOException e) {
e.printStackTrace();
}
});
t.start();
// 2. 配置 ConnectionFactory
factory = new ConnectionFactory();
