消息顺序
来自代理的消息发布到clientOutboundChannel，然后从那里写入 WebSocket 会话。由于该通道由ThreadPoolExecutor支持，因此消息在不同的线程中处理，客户端接收到的结果序列可能与发布的确切顺序不匹配。
要启用有序发布，请按如下方式设置setPreservePublishOrder标志
-
Java
-
Kotlin
-
Xml
@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>设置该标志后，同一客户端会话中的消息将一次一个地发布到clientOutboundChannel，从而保证发布顺序。请注意，这会带来少量性能开销，因此您应该仅在需要时启用它。
客户端发送到clientInboundChannel的消息也适用相同规则，然后根据其目标前缀进行处理。由于该通道由ThreadPoolExecutor支持，因此消息在不同的线程中处理，处理的结果序列可能与接收到的确切顺序不匹配。
要启用有序发布，请按如下方式设置setPreserveReceiveOrder标志
-
Java
-
Kotlin
@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)
}
}
