Performs a query, poll, insert, update or delete in a relational database using MyBatis.

Name Kind Group Required Default Type Enum Description
statement path common true java.lang.String The statement name in the MyBatis XML mapping file which maps to the query, insert, update or delete operation you wish to evaluate.
outputHeader parameter common java.lang.String Store the query result in a header instead of the message body. By default, outputHeader == null and the query result is stored in the message body, any existing content in the message body is discarded. If outputHeader is set, the value is used as the name of the header to store the query result and the original message body is preserved. Setting outputHeader will also omit populating the default CamelMyBatisResult header since it would be the same as outputHeader all the time.
bridgeErrorHandler parameter consumer boolean Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN/ERROR level and ignored.
inputHeader parameter consumer java.lang.String User the header value for input parameters instead of the message body. By default, inputHeader == null and the input parameters are taken from the message body. If outputHeader is set, the value is used and query parameters will be taken from the header instead of the body.
maxMessagesPerPoll parameter consumer 0 int This option is intended to split results returned by the database pool into the batches and deliver them in multiple exchanges. This integer defines the maximum messages to deliver in single exchange. By default, no maximum is set. Can be used to set a limit of e.g. 1000 to avoid when starting up the server that there are thousands of files. Set a value of 0 or negative to disable it.
onConsume parameter consumer java.lang.String Statement to run after data has been processed in the route
routeEmptyResultSet parameter consumer boolean Whether allow empty resultset to be routed to the next hop
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.
transacted parameter consumer boolean Enables or disables transaction. If enabled then if processing an exchange failed then the consumer + break out processing any further exchanges to cause a rollback eager
useIterator parameter consumer true boolean Process resultset individually or as a list
exceptionHandler parameter consumer (advanced) org.apache.camel.spi.ExceptionHandler To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this options is not in use. By default the consumer will deal with exceptions, that will be logged at WARN/ERROR level and ignored.
exchangePattern parameter consumer (advanced) org.apache.camel.ExchangePattern InOnly
RobustInOnly
InOut
InOptionalOut
OutOnly
RobustOutOnly
OutIn
OutOptionalIn
Sets the exchange pattern when the consumer creates an exchange.
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.
executorType parameter producer SIMPLE org.apache.ibatis.session.ExecutorType SIMPLE
REUSE
BATCH
The executor type to be used while executing statements.
  • simple - executor does nothing special.
  • reuse - executor reuses prepared statements.
  • batch - executor reuses statements and batches updates.
statementType parameter producer org.apache.camel.component.mybatis.StatementType SelectOne
SelectList
Insert
InsertList
Update
UpdateList
Delete
DeleteList
Mandatory to specify for the producer to control which kind of operation to invoke.
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. You can also specify time values using units, such as 60s (60 seconds), 5m30s (5 minutes and 30 seconds), and 1h (1 hour).
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. You can also specify time values using units, such as 60s (60 seconds), 5m30s (5 minutes and 30 seconds), and 1h (1 hour).
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 none org.apache.camel.spi.ScheduledPollConsumerScheduler none
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.
