简单代理
内置的简单消息代理处理来自客户端的订阅请求,将它们存储在内存中,并将消息广播到连接的具有匹配目标的客户端。代理支持路径样式的目标,包括对 Ant 样式目标模式的订阅。
应用程序还可以使用点分隔(而不是斜杠分隔)的目标。请参阅 点作为分隔符。 |
如果配置了任务调度器,则简单代理支持 STOMP 心跳。要配置调度器,您可以声明自己的TaskScheduler
bean 并通过MessageBrokerRegistry
设置它。或者,您可以使用内置 WebSocket 配置中自动声明的那个,但是,您需要@Lazy
来避免内置 WebSocket 配置和您的WebSocketMessageBrokerConfigurer
之间的循环。例如
-
Java
-
Kotlin
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfiguration implements WebSocketMessageBrokerConfigurer {
private TaskScheduler messageBrokerTaskScheduler;
@Autowired
public void setMessageBrokerTaskScheduler(@Lazy TaskScheduler taskScheduler) {
this.messageBrokerTaskScheduler = taskScheduler;
}
@Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
registry.enableSimpleBroker("/queue/", "/topic/")
.setHeartbeatValue(new long[] {10000, 20000})
.setTaskScheduler(this.messageBrokerTaskScheduler);
// ...
}
}
@Configuration
@EnableWebSocketMessageBroker
class WebSocketConfiguration : WebSocketMessageBrokerConfigurer {
private lateinit var messageBrokerTaskScheduler: TaskScheduler
@Autowired
fun setMessageBrokerTaskScheduler(@Lazy taskScheduler: TaskScheduler) {
this.messageBrokerTaskScheduler = taskScheduler
}
override fun configureMessageBroker(registry: MessageBrokerRegistry) {
registry.enableSimpleBroker("/queue/", "/topic/")
.setHeartbeatValue(longArrayOf(10000, 20000))
.setTaskScheduler(messageBrokerTaskScheduler)
// ...
}
}
