对于最新稳定版本，请使用 Spring Framework 7.0.6！spring-doc.cadn.net.cn

消息的顺序

来自代理（broker）的消息会被发布到 clientOutboundChannel，然后从该通道写入 WebSocket 会话。由于该通道由一个 ThreadPoolExecutor 支撑，消息会在不同的线程中被处理，因此客户端接收到的消息顺序可能与发布的精确顺序不一致。spring-doc.cadn.net.cn

要启用有序发布，请按如下方式设置 setPreservePublishOrder 标志：spring-doc.cadn.net.cn

@Configuration
@EnableWebSocketMessageBroker
public class PublishOrderWebSocketConfiguration implements WebSocketMessageBrokerConfigurer {

	@Override
	public void configureMessageBroker(MessageBrokerRegistry registry) {
		// ...
		registry.setPreservePublishOrder(true);
	}

}
@Configuration
@EnableWebSocketMessageBroker
class PublishOrderWebSocketConfiguration : WebSocketMessageBrokerConfigurer {

	override fun configureMessageBroker(registry: MessageBrokerRegistry) {
		// ...
		registry.setPreservePublishOrder(true)
	}
}
<beans xmlns="http://www.springframework.org/schema/beans"
	   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	   xmlns:websocket="http://www.springframework.org/schema/websocket"

	<websocket:message-broker preserve-publish-order="true">
		<!-- ... -->
	</websocket:message-broker>

</beans>

启用该标志后，同一客户端会话中的消息将按顺序逐个发布到 clientOutboundChannel，从而保证消息的发布顺序。 请注意，这会带来轻微的性能开销，因此仅在必要时才应启用此功能。spring-doc.cadn.net.cn

同样，这也适用于来自客户端的消息，这些消息被发送到 clientInboundChannel， 并根据其目标前缀进行处理。由于该通道由 ThreadPoolExecutor 支撑， 消息会在不同的线程中被处理，因此处理结果的顺序可能与接收时的确切顺序不一致。spring-doc.cadn.net.cn

要启用有序接收，请按如下方式设置 setPreserveReceiveOrder 标志：spring-doc.cadn.net.cn

@Configuration
@EnableWebSocketMessageBroker
public class ReceiveOrderWebSocketConfiguration implements WebSocketMessageBrokerConfigurer {

	@Override
	public void registerStompEndpoints(StompEndpointRegistry registry) {
		registry.setPreserveReceiveOrder(true);
	}
}
@Configuration
@EnableWebSocketMessageBroker
class ReceiveOrderWebSocketConfiguration : WebSocketMessageBrokerConfigurer {

	override fun registerStompEndpoints(registry: StompEndpointRegistry) {
		registry.setPreserveReceiveOrder(true)
	}
}
