这里是一个使用Spring Boot WebFlux结合Servlet和WebSocket的示例代码:
首先,确保在pom.xml文件中添加以下依赖:
<dependencies> <!-- Spring Boot WebFlux --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-webflux</artifactId> </dependency> <!-- Servlet API --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> </dependency> <!-- WebSocket --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-websocket</artifactId> </dependency> </dependencies>
接下来,创建一个Spring Boot启动类,并使用 @EnableWebFlux
注解启用WebFlux支持。这个类应该类似于以下代码:
import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.web.reactive.config.EnableWebFlux; @SpringBootApplication @EnableWebFlux public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } }
然后,创建一个处理器类,负责处理WebSocket连接和消息的交互。这个类应该实现 WebSocketHandler
接口,并使用 @Component
注解进行组件扫描。以下是一个示例:
import org.springframework.stereotype.Component; import org.springframework.web.reactive.socket.WebSocketHandler; import org.springframework.web.reactive.socket.WebSocketSession; import reactor.core.publisher.Mono; @Component public class MyWebSocketHandler implements WebSocketHandler { @Override public Mono<Void> handle(WebSocketSession session) { // 在这里处理WebSocket连接和消息的交互逻辑 return session.send(session.receive() .map(msg -> session.textMessage("Received your message: " + msg.getPayloadAsText()))); } }
然后,创建一个处理器类,负责处理WebSocket连接和消息的交互。这个类应该实现 WebSocketHandler
接口,并使用 @Component
注解进行组件扫描。以下是一个示例:
import org.springframework.stereotype.Component; import org.springframework.web.reactive.socket.WebSocketHandler; import org.springframework.web.reactive.socket.WebSocketSession; import reactor.core.publisher.Mono; @Component public class MyWebSocketHandler implements WebSocketHandler { @Override public Mono<Void> handle(WebSocketSession session) { // 在这里处理WebSocket连接和消息的交互逻辑 return session.send(session.receive() .map(msg -> session.textMessage("Received your message: " + msg.getPayloadAsText()))); } }
最后,创建一个配置类,用于注册servlet并将WebSocketHandler映射到URL路径。这个类应该类似于以下代码:
import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.web.reactive.HandlerMapping; import org.springframework.web.reactive.handler.SimpleUrlHandlerMapping; import org.springframework.web.reactive.socket.server.support.WebSocketHandlerAdapter; import org.springframework.web.util.pattern.PathPatternParser; import java.util.HashMap; import java.util.Map; @Configuration public class WebSocketConfig { @Bean public HandlerMapping handlerMapping() { Map<String, WebSocketHandler> map = new HashMap<>(); map.put("/websocket-route", new MyWebSocketHandler()); SimpleUrlHandlerMapping mapping = new SimpleUrlHandlerMapping(); mapping.setUrlMap(map); mapping.setOrder(1); return mapping; } @Bean public WebSocketHandlerAdapter handlerAdapter() { return new WebSocketHandlerAdapter(); } }
现在,您可以运行应用程序,并通过"/websocket-route"路径访问WebSocket连接。
这只是一个简单的示例,您可以根据自己的需求进行扩展和定制。希望对您有所帮助!
