Method Detail

setRequestChannel

public void setRequestChannel(MessageChannel requestChannel)

Set the request channel.

Parameters:

requestChannel - the channel to which request messages will be sent

setReplyChannel

public void setReplyChannel(MessageChannel replyChannel)

Set the reply channel. If no reply channel is provided, this template will always use an anonymous, temporary channel for handling replies.

Parameters:

replyChannel - the channel from which reply messages will be received

setRequestTimeout

public void setRequestTimeout(long requestTimeout)

Set the timeout value for sending request messages. If not explicitly configured, the default is an indefinite timeout.

Parameters:

requestTimeout - the timeout value in milliseconds

setReplyTimeout

public void setReplyTimeout(long replyTimeout)

Set the timeout value for receiving reply messages. If not explicitly configured, the default is an indefinite timeout.

Parameters:

replyTimeout - the timeout value in milliseconds

setShouldThrowErrors

public void setShouldThrowErrors(boolean shouldThrowErrors)

Specify whether the Throwable payload of a received ErrorMessage should be extracted and thrown from a send-and-receive operation. Otherwise, the ErrorMessage would be returned just like any other reply Message. The default is true.
