Constructor Details

SimpleBrokerRegistration

public SimpleBrokerRegistration(SubscribableChannel clientInboundChannel,
 MessageChannel clientOutboundChannel,
 String[] destinationPrefixes)

Create a new SimpleBrokerRegistration.

Parameters:

clientInboundChannel - the inbound channel

clientOutboundChannel - the outbound channel

destinationPrefixes - the destination prefixes

Method Details

setTaskScheduler

public SimpleBrokerRegistration 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.

Since:

4.2

setHeartbeatValue

public SimpleBrokerRegistration setHeartbeatValue(long[] heartbeat)

Configure the value for the heartbeat 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).

Since:

4.2

setSelectorHeaderName

public void setSelectorHeaderName(@Nullable
 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.

Parameters:

selectorHeaderName - the name to use for a selector header

Since:

4.3.17
