Method Detail

from

public static IntegrationFlowBuilder from(String messageChannelName)

Populate the MessageChannel name to the new IntegrationFlowBuilder chain. The IntegrationFlow inputChannel.

Parameters:

messageChannelName - the name of existing MessageChannel bean. The new DirectChannel bean will be created on context startup if there is no bean with this name.

Returns:

new IntegrationFlowBuilder.

from

public static IntegrationFlowBuilder from(String messageChannelName,
                                          boolean fixedSubscriber)

Populate the MessageChannel name to the new IntegrationFlowBuilder chain. Typically for the FixedSubscriberChannel together with fixedSubscriber = true. The IntegrationFlow inputChannel.

Parameters:

messageChannelName - the name for DirectChannel or FixedSubscriberChannel to be created on context startup, not reference. The MessageChannel depends on the fixedSubscriber boolean argument.

fixedSubscriber - the boolean flag to determine if result MessageChannel should be DirectChannel, if false or FixedSubscriberChannel, if true.

Returns:

new IntegrationFlowBuilder.
