WebSocketSession需要什么依赖
时间: 2023-07-06 10:19:41 浏览: 133
使用WebSocketSession需要引入以下依赖:
```xml
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-websocket</artifactId>
<version>5.2.9.RELEASE</version>
</dependency>
```
此外,如果你使用的是Spring Boot项目,可以使用以下依赖简化配置:
```xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-websocket</artifactId>
</dependency>
```

springboot websocket session共享 代码编写
你好,关于springboot websocket session共享的代码编写,可以使用Spring的内置WebSocket支持来实现。下面是参考示例代码:
1、首先,在Spring boot项目的依赖中加入WebSocket支持:
```
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-websocket</artifactId>
</dependency>
```
2、编写WebSocket配置类:
```
@Configuration
@EnableWebSocket
public class WebSocketConfig implements WebSocketConfigurer {
@Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
registry.addHandler(myHandler(), "/myHandler").setAllowedOrigins("*");
}
@Bean
public WebSocketHandler myHandler() {
return new MyWebSocketHandler();
}
}
```
3、实现WebSocketHandler接口:
```
public class MyWebSocketHandler implements WebSocketHandler {
private List<WebSocketSession> sessions = new ArrayList<>();
@Override
public void afterConnectionEstablished(WebSocketSession session) throws Exception {
sessions.add(session);
}
@Override
public void handleTextMessage(WebSocketSession session, TextMessage message) throws Exception {
for (WebSocketSession s : sessions) {
s.sendMessage(message);
}
}
@Override
public void afterConnectionClosed(WebSocketSession session, CloseStatus closeStatus) throws Exception {
sessions.remove(session);
}
@Override
public void handleTransportError(WebSocketSession session, Throwable exception) throws Exception {
sessions.remove(session);
}
}
```
4、在需要共享session的Controller中注入WebSocketSession对象:
```
@Controller
public class MyController {
@Autowired
private WebSocketSession webSocketSession;
@MessageMapping("/sendMessage")
@SendTo("/topic/messages")
public String sendMessage(String message) throws Exception {
webSocketSession.sendMessage(new TextMessage(message));
return message;
}
}
```
以上代码仅供参考,具体实现需根据业务需求进行改造。希望能对你有所帮助!
WebSocketSession maven引入
要在Maven项目中使用WebSocketSession,可以在pom.xml文件中添加以下依赖:
```
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-websocket</artifactId>
<version>5.3.8</version>
</dependency>
```
这将向项目中添加Spring框架的spring-websocket模块,其中包含WebSocketSession的实现。请确保您的项目已配置为使用Maven构建,并且已正确设置了您的依赖关系。
