springboot websocket 服务端
在Spring Boot中使用WebSocket实现服务端和Java客户端的实时通信，可以分为几个步骤来完成。这里将详细介绍服务端和Java客户端的具体实现。
服务端设置
添加依赖： 在pom.xml文件中添加Spring WebSocket的依赖。
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-websocket</artifactId></dependency>配置WebSocket处理器： 创建一个配置类来注册WebSocket的Endpoint。
import org.springframework.context.annotation.Configuration;import org.springframework.web.socket.config.annotation.EnableWebSocket;import org.springframework.web.socket.config.annotation.WebSocketConfigurer;import org.springframework.web.socket.config.annotation.WebSocketHandlerRegistry;import org.springframework.web.socket.WebSocketHandler;import org.springframework.web.socket.server.support.HttpSessionHandshakeInterceptor;@Configuration@EnableWebSocketpublic class WebSocketConfig implements WebSocketConfigurer {private final WebSocketHandler webSocketHandler;public WebSocketConfig(WebSocketHandler webSocketHandler) {this.webSocketHandler = webSocketHandler;}@Overridepublic void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {registry.addHandler(webSocketHandler, "/ws/chat").addInterceptors(new HttpSessionHandshakeInterceptor()).setAllowedOrigins("*");}} import org.springframework.context.annotation.Configuration;import org.springframework.web.socket.config.annotation.EnableWebSocket;import org.springframework.web.socket.config.annotation.WebSocketConfigurer;import org.springframework.web.socket.config.annotation.WebSocketHandlerRegistry;import org.springframework.web.socket.WebSocketHandler;import org.springframework.web.socket.server.support.HttpSessionHandshakeInterceptor;@Configuration@EnableWebSocketpublic class WebSocketConfig implements WebSocketConfigurer {private final WebSocketHandler webSocketHandler;public WebSocketConfig(WebSocketHandler webSocketHandler) {this.webSocketHandler = webSocketHandler;}@Overridepublic void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {registry.addHandler(webSocketHandler, "/ws/chat").addInterceptors(new HttpSessionHandshakeInterceptor()).setAllowedOrigins("*");}}
