方法详细资料

• setSubscriptionRegistry

  public void setSubscriptionRegistry​(SubscriptionRegistry subscriptionRegistry)

  Configure a custom SubscriptionRegistry to use for storing subscriptions.

  Note that when a custom PathMatcher is configured via setPathMatcher(org.springframework.util.PathMatcher), if the custom registry is not an instance of DefaultSubscriptionRegistry, the provided PathMatcher is not used and must be configured directly on the custom registry.

• getSubscriptionRegistry

  public SubscriptionRegistry getSubscriptionRegistry()

• setSelectorHeaderName

  public void setSelectorHeaderName​(String selectorHeaderName)

  Configure the name of a header that a subscription message can have for the purpose of filtering messages matched to the subscription. The header value is expected to be a Spring EL boolean expression to be applied to the headers of messages matched to the subscription.

  For example:

   headers.foo == 'bar'
   

  By default this is set to "selector". You can set it to a different name, or to null to turn off support for a selector header.

  参数:

  selectorHeaderName - the name to use for a selector header

  从以下版本开始:

• setPathMatcher

  public void setPathMatcher​(PathMatcher pathMatcher)

  When configured, the given PathMatcher is passed down to the underlying SubscriptionRegistry to use for matching destination to subscriptions.

  Default is a standard AntPathMatcher.

  setSubscriptionRegistry(org.springframework.messaging.simp.broker.SubscriptionRegistry), DefaultSubscriptionRegistry.setPathMatcher(org.springframework.util.PathMatcher), AntPathMatcher

• setCacheLimit

  public void setCacheLimit​(Integer cacheLimit)

  When configured, the specified cache limit is passed down to the underlying SubscriptionRegistry, overriding any default there.

  With a standard DefaultSubscriptionRegistry, the default cache limit is 1024.

  从以下版本开始:

  4.3.2

  另请参阅:

  setSubscriptionRegistry(org.springframework.messaging.simp.broker.SubscriptionRegistry), DefaultSubscriptionRegistry.setCacheLimit(int), DefaultSubscriptionRegistry.DEFAULT_CACHE_LIMIT

• setTaskScheduler

  public void setTaskScheduler​(TaskScheduler taskScheduler)

  Configure the TaskScheduler to use for providing heartbeat support. Setting this property also sets the heartbeatValue to "10000, 10000".

  By default this is not set.

  从以下版本开始:

• setHeartbeatValue

  public void setHeartbeatValue​(long[] heartbeat)

  Configure the value for the heart-beat settings. The first number represents how often the server will write or send a heartbeat. The second is how often the client should write. 0 means no heartbeats.

  By default this is set to "0, 0" unless the taskScheduler in which case the default becomes "10000,10000" (in milliseconds).

• getHeartbeatValue

  public long[] getHeartbeatValue()

  The configured value for the heart-beat settings.
