JPA

JPA

Scheme: jpa
Name Kind Type Required Deprecated Default Value Enum Values Description
entityType path java.lang.Class true false The JPA annotated class to use as entity.
persistenceUnit parameter java.lang.String true false camel The JPA persistence unit used by default.
joinTransaction parameter boolean false true The camel-jpa component will join transaction by default. You can use this option to turn this off, for example if you use LOCAL_RESOURCE and join transaction doesn't work with your JPA provider. This option can also be set globally on the JpaComponent, instead of having to set it on all endpoints.
maximumResults parameter int false -1 Set the maximum number of results to retrieve on the Query.
consumeDelete parameter boolean false true If true, the entity is deleted after it is consumed; if false, the entity is not deleted.
consumeLockEntity parameter boolean false true Specifies whether or not to set an exclusive lock on each entity bean while processing the results from polling.
maxMessagesPerPoll parameter int false An integer value to define the maximum number of messages to gather per poll. By default, no maximum is set. Can be used to avoid polling many thousands of messages when starting up the server. Set a value of 0 or negative to disable.
flushOnSend parameter boolean false true Flushes the EntityManager after the entity bean has been persisted.
usePersist parameter boolean false Indicates to use entityManager.persist(entity) instead of entityManager.merge(entity). Note: entityManager.persist(entity) doesn't work for detached entities (where the EntityManager has to execute an UPDATE instead of an INSERT query)!
usePassedInEntityManager parameter boolean false If set to true, then Camel will use the EntityManager from the header JpaConstants.ENTITYMANAGER instead of the configured entity manager on the component/endpoint. This allows end users to control which entity manager will be in use.
startScheduler parameter boolean false true Whether the scheduler should be auto started.
initialDelay parameter long false 1000 Milliseconds before the first poll starts.
delay parameter long false 500 Milliseconds before the next poll.
timeUnit parameter java.util.concurrent.TimeUnit false MILLISECONDS NANOSECONDS
MICROSECONDS
MILLISECONDS
SECONDS
MINUTES
HOURS
DAYS
Time unit for initialDelay and delay options.
useFixedDelay parameter boolean false true Controls if fixed delay or fixed rate is used. See ScheduledExecutorService in JDK for details.
pollStrategy parameter org.apache.camel.spi.PollingConsumerPollStrategy false 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.
runLoggingLevel parameter org.apache.camel.LoggingLevel false TRACE DEBUG
ERROR
INFO
TRACE
WARN
OFF
The consumer logs a start/complete log line when it polls. This option allows you to configure the logging level for that.
sendEmptyMessageWhenIdle parameter boolean false If the polling consumer did not poll any files, you can enable this option to send an empty message (no body) instead.
greedy parameter boolean false If greedy is enabled, then the ScheduledPollConsumer will run immediately again, if the previous run polled 1 or more messages.
scheduler parameter org.apache.camel.spi.ScheduledPollConsumerScheduler false spring
quartz2
To use a cron scheduler from either camel-spring or camel-quartz2 component
schedulerProperties parameter java.util.Map false To configure additional properties when using a custom scheduler or any of the Quartz2, Spring based scheduler.
scheduledExecutorService parameter java.util.concurrent.ScheduledExecutorService false Allows for configuring a custom/shared thread pool to use for the consumer. By default each consumer has its own single threaded thread pool.
backoffMultiplier parameter int false 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.
backoffIdleThreshold parameter int false The number of subsequent idle polls that should happen before the backoffMultipler should kick-in.
backoffErrorThreshold parameter int false The number of subsequent error polls (failed due some error) that should happen before the backoffMultipler should kick-in.
exchangePattern parameter org.apache.camel.ExchangePattern false InOnly InOnly
RobustInOnly
InOut
InOptionalOut
OutOnly
RobustOutOnly
OutIn
OutOptionalIn
Sets the default exchange pattern when creating an exchange
synchronous parameter boolean false false Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).
