WebSocket is based on STOMP
The essence of stomp is the broadcast mode, so the secondary socket is more suitable for broadcasting Instructions: rely: <!–websocket–> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-websocket</artifactId> </dependency> Configuration class: package com.matrix.npdm.config; import org.springframework.context.annotation.Configuration; import org.springframework.messaging.converter.MessageConverter; import org.springframework.messaging.handler.invocation.HandlerMethodArgumentResolver; import org.springframework.messaging.handler.invocation.HandlerMethodReturnValueHandler; import org.springframework.messaging.simp.config.ChannelRegistration; 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; import org.springframework.web.socket.config.annotation.WebSocketTransportRegistration; import java.util.List; /** Endpoint configuration * Passive […]
