以下是一个简单的Spring Cloud Gateway配置WebSocket的例子:
1. 添加依赖
在pom.xml文件中添加以下依赖:
```xml
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-gateway</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-websocket</artifactId>
</dependency>
```
2. 配置Gateway
在application.yml文件中添加以下配置:
```yaml
spring:
cloud:
gateway:
routes:
- id: ws_route
uri: ws://localhost:8081
predicates:
- Path=/websocket/**
filters:
- WebSocket
```
这个配置将会将所有以`/websocket`开头的请求路由到`ws://localhost:8081`。
3. 配置WebSocket处理器
创建一个WebSocket处理器类:
```java
@Component
public class MyWebSocketHandler extends TextWebSocketHandler {
@Override
public void handleTextMessage(WebSocketSession session, TextMessage message) throws IOException {
// 处理消息
session.sendMessage(new TextMessage("Received: " + message.getPayload()));
}
}
```
4. 配置WebSocketHandlerAdapter
创建一个WebSocketHandlerAdapter类,用于将WebSocket处理器集成到Spring MVC中:
```java
@Configuration
public class WebSocketConfig {
@Bean
public WebSocketHandlerAdapter handlerAdapter() {
return new WebSocketHandlerAdapter();
}
}
```
5. 启动WebSocket服务器
创建一个WebSocket服务器类:
```java
@Configuration
@EnableWebSocket
public class WebSocketServerConfig implements WebSocketConfigurer {
@Autowired
private MyWebSocketHandler myWebSocketHandler;
@Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
registry.addHandler(myWebSocketHandler, "/websocket");
}
}
```
在启动类中添加@EnableWebSocketServer注解:
```java
@SpringBootApplication
@EnableWebSocketServer
public class GatewayApplication {
public static void main(String[] args) {
SpringApplication.run(GatewayApplication.class, args);
}
}
```
6. 测试WebSocket
使用WebSocket客户端连接到`ws://localhost:8080/websocket`,并发送一条消息,应该能够收到处理后的消息。
以上就是配置Spring Cloud Gateway支持WebSocket的简单例子。
