Description: Camel Velocity support
Scheme: velocity
Syntax: velocity:resourceUri
Maven: org.apache.camel/camel-velocity/2.16.1
Name Kind Group Required Default Type Enum Description
resourceUri path producer true java.lang.String Path to the resource
sendEmptyMessageWhenIdle parameter consumer boolean If the polling consumer did not poll any files, you can enable this option to send an empty message (no body) instead.
pollStrategy parameter consumer (advanced) org.apache.camel.spi.PollingConsumerPollStrategy A pluggable org.apache.camel.PollingConsumerPollingStrategy allowing you to provide your custom implementation to control error handling usually occurred during the poll operation before an Exchange have been created and being routed in Camel.
contentCache parameter producer false boolean Sets whether to use resource content cache or not
encoding parameter producer java.lang.String Character encoding of the resource content.
loaderCache parameter producer true boolean Enables / disables the velocity resource loader cache which is enabled by default
propertiesFile parameter producer java.lang.String The URI of the properties file which is used for VelocityEngine initialization.
exchangePattern parameter advanced InOnly org.apache.camel.ExchangePattern InOnly
RobustInOnly
InOut
InOptionalOut
OutOnly
RobustOutOnly
OutIn
OutOptionalIn
Sets the default exchange pattern when creating an exchange
synchronous parameter advanced false boolean Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).
backoffErrorThreshold parameter scheduler int The number of subsequent error polls (failed due some error) that should happen before the backoffMultipler should kick-in.
backoffIdleThreshold parameter scheduler int The number of subsequent idle polls that should happen before the backoffMultipler should kick-in.
backoffMultiplier parameter scheduler int To let the scheduled polling consumer backoff if there has been a number of subsequent idles/errors in a row. The multiplier is then the number of polls that will be skipped before the next actual attempt is happening again. When this option is in use then backoffIdleThreshold and/or backoffErrorThreshold must also be configured.
delay parameter scheduler 500 long Milliseconds before the next poll.
greedy parameter scheduler boolean If greedy is enabled, then the ScheduledPollConsumer will run immediately again, if the previous run polled 1 or more messages.
initialDelay parameter scheduler 1000 long Milliseconds before the first poll starts.
runLoggingLevel parameter scheduler TRACE org.apache.camel.LoggingLevel TRACE
DEBUG
INFO
WARN
ERROR
OFF
The consumer logs a start/complete log line when it polls. This option allows you to configure the logging level for that.
scheduledExecutorService parameter scheduler java.util.concurrent.ScheduledExecutorService Allows for configuring a custom/shared thread pool to use for the consumer. By default each consumer has its own single threaded thread pool.
scheduler parameter scheduler org.apache.camel.spi.ScheduledPollConsumerScheduler spring
quartz2
To use a cron scheduler from either camel-spring or camel-quartz2 component
schedulerProperties parameter scheduler java.util.Map To configure additional properties when using a custom scheduler or any of the Quartz2, Spring based scheduler.
startScheduler parameter scheduler true boolean Whether the scheduler should be auto started.
timeUnit parameter scheduler MILLISECONDS java.util.concurrent.TimeUnit NANOSECONDS
MICROSECONDS
MILLISECONDS
SECONDS
MINUTES
HOURS
DAYS
Time unit for initialDelay and delay options.
useFixedDelay parameter scheduler true boolean Controls if fixed delay or fixed rate is used. See ScheduledExecutorService in JDK for details.
