wss是WebSocket Secure的缩写,是一种在互联网上进行实时双向通信的协议,通过安全的TLS/SSL加密,保证了数据传输的安全性。wss通过建立持久化的连接,使得服务器能够主动向客户端推送数据,实现了实时性的双向通信。
Grails 3是一种基于Groovy语言和Java虚拟机(JVM)的开发框架,它结合了Spring Boot和Grails框架的优势,提供了快速开发Web应用的能力。Grails 3使用Grails插件和约定优于配置的原则,简化了开发流程,提高了开发效率。
在将wss与Grails 3连接起来时,需要进行以下步骤:
AbstractWebSocketMessageBrokerConfigurer
,并实现registerStompEndpoints()
方法来配置WebSocket端点。例如:import org.springframework.context.annotation.Configuration
import org.springframework.messaging.simp.config.MessageBrokerRegistry
import org.springframework.web.socket.config.annotation.EnableWebSocketMessageBroker
import org.springframework.web.socket.config.annotation.StompEndpointRegistry
import org.springframework.web.socket.config.annotation.WebSocketMessageBrokerConfigurer
@Configuration
@EnableWebSocketMessageBroker
class WebSocketConfig implements WebSocketMessageBrokerConfigurer {
@Override
void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/websocket").withSockJS()
}
@Override
void configureMessageBroker(MessageBrokerRegistry registry) {
registry.enableSimpleBroker("/topic")
registry.setApplicationDestinationPrefixes("/app")
}
}
WebSocketHandler
接口,并重写相应的方法。例如:import org.springframework.web.socket.CloseStatus
import org.springframework.web.socket.TextMessage
import org.springframework.web.socket.WebSocketHandler
import org.springframework.web.socket.WebSocketSession
class MyWebSocketHandler implements WebSocketHandler {
@Override
void afterConnectionEstablished(WebSocketSession session) throws Exception {
// 当与WebSocket建立连接时调用,可以进行一些初始化操作
}
@Override
void handleMessage(WebSocketSession session, WebSocketMessage<?> message) throws Exception {
// 当接收到客户端的消息时调用,可以进行消息处理
}
@Override
void handleTransportError(WebSocketSession session, Throwable exception) throws Exception {
// 当发生传输错误时调用,可以进行错误处理
}
@Override
void afterConnectionClosed(WebSocketSession session, CloseStatus closeStatus) throws Exception {
// 当与WebSocket关闭连接时调用,可以进行资源清理操作
}
@Override
boolean supportsPartialMessages() {
// 是否支持部分消息传输
return false
}
}
@Bean
注解,将自定义的WebSocket处理器注册到应用中。例如:import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.Configuration
import org.springframework.messaging.simp.config.MessageBrokerRegistry
import org.springframework.web.socket.config.annotation.EnableWebSocketMessageBroker
import org.springframework.web.socket.config.annotation.StompEndpointRegistry
import org.springframework.web.socket.config.annotation.WebSocketMessageBrokerConfigurer
@Configuration
@EnableWebSocketMessageBroker
class WebSocketConfig implements WebSocketMessageBrokerConfigurer {
@Override
void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/websocket").withSockJS()
}
@Override
void configureMessageBroker(MessageBrokerRegistry registry) {
registry.enableSimpleBroker("/topic")
registry.setApplicationDestinationPrefixes("/app")
}
@Bean
WebSocketHandler myWebSocketHandler() {
return new MyWebSocketHandler()
}
}
