要在Spring Boot中集成WebSocket,可以按照以下步骤进行操作:
1. 添加Spring Boot WebSocket依赖项
2. 创建WebSocket配置类
3. 创建WebSocket处理程序类
4. 在Spring Boot应用程序中启用WebSocket
下面是一个简单的示例代码:
1. 添加Spring Boot WebSocket依赖项
在pom.xml文件中添加以下依赖项:
```
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-websocket</artifactId>
</dependency>
```
2. 创建WebSocket配置类
创建一个WebSocket配置类,用于配置WebSocket相关的参数,例如消息代理、消息端点等。示例代码如下:
```
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {
@Override
public void configureMessageBroker(MessageBrokerRegistry config) {
config.enableSimpleBroker("/topic");
config.setApplicationDestinationPrefixes("/app");
}
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/websocket").withSockJS();
}
}
```
3. 创建WebSocket处理程序类
创建一个WebSocket处理程序类,用于处理WebSocket连接、消息发送等操作。示例代码如下:
```
@Controller
public class WebSocketController {
@MessageMapping("/hello")
@SendTo("/topic/greetings")
public Greeting greeting(HelloMessage message) throws Exception {
Thread.sleep(1000); // simulated delay
return new Greeting("Hello, " + message.getName() + "!");
}
}
```
4. 在Spring Boot应用程序中启用WebSocket
在Spring Boot应用程序的启动类上添加@EnableWebSocket注解,启用WebSocket功能。示例代码如下:
```
@SpringBootApplication
@EnableWebSocket
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
```
