SpringBoot netty-socketio服务器端推送 SpringBoot+netty-socketio实现服务器端消息推送
ATwill... 人气:0想了解SpringBoot+netty-socketio实现服务器端消息推送的相关内容吗,ATwill...在本文为您仔细讲解SpringBoot netty-socketio服务器端推送的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:SpringBoot,netty-socketio服务器端推送,SpringBoot,netty-socketio推送,下面大家一起来学习吧。
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"; } }
