Construct an instance with the provided delegateCommonErrorHandlers.- Parameters:
recordErrorHandler- the error handler for record listeners.batchErrorHandler- the error handler for batch listeners.

Method Detail
-
remainingRecords
public boolean remainingRecords()
Description copied from interface:CommonErrorHandlerReturn false if this error handler should only receive the current failed record; remaining records will be passed to the listener after the error handler returns. When true (default), all remaining records including the failed record are passed to the error handler.- Specified by:
remainingRecordsin interfaceCommonErrorHandler- Returns:
- false to receive only the failed record.
- See Also:
CommonErrorHandler.handleRecord(Exception, ConsumerRecord, Consumer, MessageListenerContainer),CommonErrorHandler.handleRemaining(Exception, List, Consumer, MessageListenerContainer)
-
deliveryAttemptHeader
public boolean deliveryAttemptHeader()
Description copied from interface:CommonErrorHandlerReturn true if this error handler supports delivery attempts headers.- Specified by:
deliveryAttemptHeaderin interfaceCommonErrorHandler- Returns:
- true if capable.
-
handleOtherException
public void handleOtherException(java.lang.Exception thrownException, org.apache.kafka.clients.consumer.Consumer<?,?> consumer, MessageListenerContainer container, boolean batchListener)Description copied from interface:CommonErrorHandlerCalled when an exception is thrown with no records available, e.g. if the consumer poll throws an exception.- Specified by:
handleOtherExceptionin interfaceCommonErrorHandler- Parameters:
thrownException- the exception.consumer- the consumer.container- the container.batchListener- true if the listener is a batch listener.
-
handleRecord
public void handleRecord(java.lang.Exception thrownException, org.apache.kafka.clients.consumer.ConsumerRecord<?,?> record, org.apache.kafka.clients.consumer.Consumer<?,?> consumer, MessageListenerContainer container)Description copied from interface:CommonErrorHandlerHandle the exception for a record listener whenCommonErrorHandler.remainingRecords()returns false. Use this to handle just the single failed record; remaining records from the poll will be sent to the listener.- Specified by:
handleRecordin interfaceCommonErrorHandler- Parameters:
thrownException- the exception.record- the record.consumer- the consumer.container- the container.- See Also:
CommonErrorHandler.remainingRecords()
-
handleRemaining
public void handleRemaining(java.lang.Exception thrownException, java.util.List<org.apache.kafka.clients.consumer.ConsumerRecord<?,?>> records, org.apache.kafka.clients.consumer.Consumer<?,?> consumer, MessageListenerContainer container)Description copied from interface:CommonErrorHandlerHandle the exception for a record listener whenCommonErrorHandler.remainingRecords()returns true. The failed record and all the remaining records from the poll are passed in. Usually used when the error handler performs seeks so that the remaining records will be redelivered on the next poll.- Specified by:
handleRemainingin interfaceCommonErrorHandler- Parameters:
thrownException- the exception.records- the remaining records including the one that failed.consumer- the consumer.container- the container.- See Also:
CommonErrorHandler.remainingRecords()
-
handleBatch
public void handleBatch(java.lang.Exception thrownException, org.apache.kafka.clients.consumer.ConsumerRecords<?,?> data, org.apache.kafka.clients.consumer.Consumer<?,?> consumer, MessageListenerContainer container, java.lang.Runnable invokeListener)Description copied from interface:CommonErrorHandlerHandle the exception for a batch listener. The completeConsumerRecordsfrom the poll is supplied. The error handler needs to perform seeks if you wish to reprocess the records in the batch.- Specified by:
handleBatchin interfaceCommonErrorHandler- Parameters:
thrownException- the exception.data- the consumer records.consumer- the consumer.container- the container.invokeListener- a callback to re-invoke the listener.
-
deliveryAttempt
public int deliveryAttempt(TopicPartitionOffset topicPartitionOffset)
Description copied from interface:DeliveryAttemptAwareReturn the next delivery attempt for the topic/partition/offset.- Specified by:
deliveryAttemptin interfaceCommonErrorHandler- Specified by:
deliveryAttemptin interfaceDeliveryAttemptAware- Parameters:
topicPartitionOffset- the topic/partition/offset.- Returns:
- the next delivery attempt.
-
clearThreadState
public void clearThreadState()
Description copied from interface:CommonErrorHandlerOptional method to clear thread state; will be called just before a consumer thread terminates.- Specified by:
clearThreadStatein interfaceCommonErrorHandler
-
isAckAfterHandle
public boolean isAckAfterHandle()
Description copied from interface:CommonErrorHandlerReturn true if the offset should be committed for a handled error (no exception thrown).- Specified by:
isAckAfterHandlein interfaceCommonErrorHandler- Returns:
- true to commit.
-
setAckAfterHandle
public void setAckAfterHandle(boolean ack)
Description copied from interface:CommonErrorHandlerSet to false to prevent the container from committing the offset of a recovered record (when the error handler does not itself throw an exception).- Specified by:
setAckAfterHandlein interfaceCommonErrorHandler- Parameters:
ack- false to not commit.
