SpringBoot+netty-socketio实现服务器端消息推送

首先：因为工作需要，需要对接socket.io框架对接，所以目前只能使用netty-socketio。websocket是不支持对接socket.io框架的。

netty-socketio顾名思义他是一个底层基于netty'实现的socket。

在springboot项目中的集成，请看下面的代码

maven依赖

<dependency>
 <groupId>com.corundumstudio.socketio</groupId>
 <artifactId>netty-socketio</artifactId>
 <version>1.7.11</version>
</dependency>

 下面就是代码了

首先是配置参数

#socketio配置
socketio:
 host: localhost
 port: 9099
 # 设置最大每帧处理数据的长度，防止他人利用大数据来攻击服务器
 maxFramePayloadLength: 1048576
 # 设置http交互最大内容长度
 maxHttpContentLength: 1048576
 # socket连接数大小（如只监听一个端口boss线程组为1即可）
 bossCount: 1
 workCount: 100
 allowCustomRequests: true
 # 协议升级超时时间（毫秒），默认10秒。HTTP握手升级为ws协议超时时间
 upgradeTimeout: 1000000
 # Ping消息超时时间（毫秒），默认60秒，这个时间间隔内没有接收到心跳消息就会发送超时事件
 pingTimeout: 6000000
 # Ping消息间隔（毫秒），默认25秒。客户端向服务器发送一条心跳消息间隔
 pingInterval: 25000

上面的注释写的很清楚。下面是config代码

import com.corundumstudio.socketio.Configuration;
import com.corundumstudio.socketio.SocketConfig;
import com.corundumstudio.socketio.SocketIOServer;
import org.springframework.beans.factory.InitializingBean;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

import javax.annotation.Resource;

/**
 * kcm
 */
@Component
public class PushServer implements InitializingBean {

  @Autowired
  private EventListenner eventListenner;

  @Value("${socketio.port}")
  private int serverPort;

  @Value("${socketio.host}")
  private String serverHost;

  @Value("${socketio.bossCount}")
  private int bossCount;

  @Value("${socketio.workCount}")
  private int workCount;

  @Value("${socketio.allowCustomRequests}")
  private boolean allowCustomRequests;

  @Value("${socketio.upgradeTimeout}")
  private int upgradeTimeout;

  @Value("${socketio.pingTimeout}")
  private int pingTimeout;

  @Value("${socketio.pingInterval}")
  private int pingInterval;

  @Override
  public void afterPropertiesSet() throws Exception {
    Configuration config = new Configuration();
    config.setPort(serverPort);
    config.setHostname(serverHost);
    config.setBossThreads(bossCount);
    config.setWorkerThreads(workCount);
    config.setAllowCustomRequests(allowCustomRequests);
    config.setUpgradeTimeout(upgradeTimeout);
    config.setPingTimeout(pingTimeout);
    config.setPingInterval(pingInterval);

    SocketConfig socketConfig = new SocketConfig();
    socketConfig.setReuseAddress(true);
    socketConfig.setTcpNoDelay(true);
    socketConfig.setSoLinger(0);
    config.setSocketConfig(socketConfig);

    SocketIOServer server = new SocketIOServer(config);
    server.addListeners(eventListenner);
    server.start();
    System.out.println("启动正常");
  }
}

在就是监听代码

import com.corundumstudio.socketio.AckRequest;
import com.corundumstudio.socketio.SocketIOClient;
import com.corundumstudio.socketio.annotation.OnConnect;
import com.corundumstudio.socketio.annotation.OnDisconnect;
import com.corundumstudio.socketio.annotation.OnEvent;
import org.apache.commons.lang3.StringUtils;
import org.bangying.auth.JwtSupport;
import org.springframework.stereotype.Component;

import javax.annotation.Resource;
import java.util.UUID;

@Component
public class EventListenner {
  @Resource
  private ClientCache clientCache;

  @Resource
  private JwtSupport jwtSupport;

  /**
   * 客户端连接
   *
   * @param client
   */
  @OnConnect
  public void onConnect(SocketIOClient client) {
    String userId = client.getHandshakeData().getSingleUrlParam("userId");
//    userId = jwtSupport.getApplicationUser().getId().toString();
//    userId = "8";
    UUID sessionId = client.getSessionId();
    clientCache.saveClient(userId, sessionId, client);
    System.out.println("建立连接");
  }

  /**
   * 客户端断开
   *
   * @param client
   */
  @OnDisconnect
  public void onDisconnect(SocketIOClient client) {
    String userId = client.getHandshakeData().getSingleUrlParam("userId");
    if (StringUtils.isNotBlank(userId)) {
      clientCache.deleteSessionClient(userId, client.getSessionId());
      System.out.println("关闭连接");
    }
  }

  //消息接收入口，当接收到消息后，查找发送目标客户端，并且向该客户端发送消息，且给自己发送消息
  // 暂未使用
  @OnEvent("messageevent")
  public void onEvent(SocketIOClient client, AckRequest request) {
  }
}

本地缓存信息

import com.corundumstudio.socketio.SocketIOClient;
import org.apache.commons.lang3.StringUtils;
import org.springframework.stereotype.Component;

import java.util.HashMap;
import java.util.Map;
import java.util.UUID;
import java.util.concurrent.ConcurrentHashMap;

/**
 * kcm
 */
@Component
public class ClientCache {

  //本地缓存
  private static Map<String, HashMap<UUID, SocketIOClient>> concurrentHashMap=new ConcurrentHashMap<>();
  /**
   * 存入本地缓存
   * @param userId 用户ID
   * @param sessionId 页面sessionID
   * @param socketIOClient 页面对应的通道连接信息
   */
  public void saveClient(String userId, UUID sessionId,SocketIOClient socketIOClient){
    if(StringUtils.isNotBlank(userId)){
      HashMap<UUID, SocketIOClient> sessionIdClientCache=concurrentHashMap.get(userId);
      if(sessionIdClientCache==null){
        sessionIdClientCache = new HashMap<>();
      }
      sessionIdClientCache.put(sessionId,socketIOClient);
      concurrentHashMap.put(userId,sessionIdClientCache);
    }
  }
  /**
   * 根据用户ID获取所有通道信息
   * @param userId
   * @return
   */
  public HashMap<UUID, SocketIOClient> getUserClient(String userId){
    return concurrentHashMap.get(userId);
  }
  /**
   * 根据用户ID及页面sessionID删除页面链接信息
   * @param userId
   * @param sessionId
   */
  public void deleteSessionClient(String userId,UUID sessionId){
    concurrentHashMap.get(userId).remove(sessionId);
  }
}

下面是存储客户端连接信息

import com.corundumstudio.socketio.SocketIOClient;
import org.apache.commons.lang3.StringUtils;
import org.springframework.stereotype.Component;

import java.util.HashMap;
import java.util.Map;
import java.util.UUID;
import java.util.concurrent.ConcurrentHashMap;

/**
 * kcm
 */
@Component
public class ClientCache {

  //本地缓存
  private static Map<String, HashMap<UUID, SocketIOClient>> concurrentHashMap=new ConcurrentHashMap<>();
  /**
   * 存入本地缓存
   * @param userId 用户ID
   * @param sessionId 页面sessionID
   * @param socketIOClient 页面对应的通道连接信息
   */
  public void saveClient(String userId, UUID sessionId,SocketIOClient socketIOClient){
    if(StringUtils.isNotBlank(userId)){
      HashMap<UUID, SocketIOClient> sessionIdClientCache=concurrentHashMap.get(userId);
      if(sessionIdClientCache==null){
        sessionIdClientCache = new HashMap<>();
      }
      sessionIdClientCache.put(sessionId,socketIOClient);
      concurrentHashMap.put(userId,sessionIdClientCache);
    }
  }
  /**
   * 根据用户ID获取所有通道信息
   * @param userId
   * @return
   */
  public HashMap<UUID, SocketIOClient> getUserClient(String userId){
    return concurrentHashMap.get(userId);
  }
  /**
   * 根据用户ID及页面sessionID删除页面链接信息
   * @param userId
   * @param sessionId
   */
  public void deleteSessionClient(String userId,UUID sessionId){
    concurrentHashMap.get(userId).remove(sessionId);
  }
}

控制层推送方法

@RestController
@RequestMapping("/push")
public class PushController {
  @Resource
  private ClientCache clientCache;

  @Autowired
  private JwtSupport jwtSupport;

  @GetMapping("/message")
  public String pushTuUser(@Param("id") String id){
    Integer userId = jwtSupport.getApplicationUser().getId();
    HashMap<UUID, SocketIOClient> userClient = clientCache.getUserClient(String.valueOf(userId));
    userClient.forEach((uuid, socketIOClient) -> {
      //向客户端推送消息
      socketIOClient.sendEvent("chatevent","服务端推送消息");
    });
    return "success";
  }
}
