WebSocket启用备忘

一：引入依赖：

<!--WebSocket专用--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-websocket</artifactId></dependency><dependency><groupId>org.glassfish.tyrus.bundles</groupId><artifactId>tyrus-standalone-client</artifactId><version>2.1.5</version></dependency><!--WebSocket end-->

二：写Service:

@Component
@ServerEndpoint("/websocket/tterm")
public class WebSocketServerEterm {

@OnOpen
public void onOpen(Session session) {try {_socket = new Socket(serverIp, serverPort); // 使用配置中的IP和端口if (_socket.isConnected()) {。。。}
}}

@OnMessage
public void onMessage(String command, Session session) 

@OnClose
public void onClose(Session session) {try {if (_socket != null)_socket.close();System.out.println("Socket连接关闭: " + session.getId());} catch (IOException e) {System.err.println("关闭Socket资源失败：" + e.getMessage());}
}

 三、使用

const WS_BASE_URL = import.meta.env.VITE_WS_URL;
const url = WS_BASE_URL ? `${WS_BASE_URL}/websocket/tterm` : null;
 

// 切换模态框
const toggleEtermModal = async () => {if (!url) {message.error('WebSocket服务未配置');return;}etermVisible.value = !etermVisible.value;if (etermVisible.value) {try {await nextTick();document.querySelector('.eterm-input')?.focus();etermLoading.value = true;await etermApi.connect(url, {onMessage: (data) => {etermList.value.push({command: '',response: data});scrollToBottom();},onOpen: () => {socketConnected.value = true;etermList.value.push({command: '',response: '>>> 连接成功'});},onClose: () => {socketConnected.value = false;}});} catch (error) {message.error(`连接失败: ${error.message}`);etermVisible.value = false;} finally {etermLoading.value = false;}} else {etermApi.exit();}
};

四、正式环境需要结合NGINX:
 

# WebSocket 代理配置location /api/websocket/eterm {proxy_pass http://111.222.3.4:1111/websocket/eterm;# WebSocket 必须配置proxy_http_version 1.1;proxy_set_header Upgrade $http_upgrade;proxy_set_header Connection "upgrade";proxy_set_header Host $host;# 连接超时设置proxy_read_timeout 86400s;proxy_send_timeout 86400s;proxy_connect_timeout 5s;# 日志记录access_log /var/log/nginx/websocket.log websocket;}
