Method Detail

setMaxRowsPerPoll

public void setMaxRowsPerPoll(java.lang.Integer maxRowsPerPoll)

The maximum number of rows to pull out of the query results per poll (if greater than zero, otherwise all rows will be packed into the outgoing message). The value is ultimately set on the underlying JdbcPollingChannelAdapter. If not specified this value will default to zero. This parameter is only applicable if a selectQuery was provided. Null values are not permitted.

Parameters:

maxRowsPerPoll - Must not be null.

onInit

protected void onInit()

Description copied from class: IntegrationObjectSupport

Subclasses may implement this for initialization logic.

Overrides:

onInit in class AbstractReplyProducingMessageHandler

handleRequestMessage

protected java.lang.Object handleRequestMessage(Message<?> requestMessage)

Description copied from class: AbstractReplyProducingMessageHandler

Subclasses must implement this method to handle the request Message. The return value may be a Message, a MessageBuilder, or any plain Object. The base class will handle the final creation of a reply Message from any of those starting points. If the return value is null, the Message flow will end here.

Specified by:

handleRequestMessage in class AbstractReplyProducingMessageHandler

setKeysGenerated

public void setKeysGenerated(boolean keysGenerated)

Flag to indicate that the update query is an insert with autogenerated keys, which will be logged at debug level.

Parameters:

keysGenerated - the flag value to set

setRequestSqlParameterSourceFactory

public void setRequestSqlParameterSourceFactory(SqlParameterSourceFactory sqlParameterSourceFactory)

setReplySqlParameterSourceFactory

public void setReplySqlParameterSourceFactory(SqlParameterSourceFactory sqlParameterSourceFactory)

setRowMapper

public void setRowMapper(org.springframework.jdbc.core.RowMapper<?> rowMapper)
