Constructor Details

JdbcOutboundGateway

public JdbcOutboundGateway(DataSource dataSource,
 String updateQuery)

Construct an instance based on the provided DataSource and update SQL.

Parameters:

dataSource - the DataSource for execution.

updateQuery - the query to execute.

JdbcOutboundGateway

public JdbcOutboundGateway(DataSource dataSource,
 String updateQuery,
 String selectQuery)

Construct an instance based on the provided DataSource, select and update SQLs.

Parameters:

dataSource - the DataSource for execution.

updateQuery - the update to execute.

selectQuery - the select to execute.

JdbcOutboundGateway

public JdbcOutboundGateway(JdbcOperations jdbcOperations,
 String updateQuery)

Construct an instance based on the provided JdbcOperations and update SQL.

Parameters:

jdbcOperations - the JdbcOperations for execution.

updateQuery - the query to execute.

JdbcOutboundGateway

public JdbcOutboundGateway(JdbcOperations jdbcOperations,
 String updateQuery,
 String selectQuery)

Construct an instance based on the provided JdbcOperations, select and update SQLs.

Parameters:

jdbcOperations - the JdbcOperations for execution.

updateQuery - the update to execute.

selectQuery - the select to execute.

Method Details

setMaxRows

public void setMaxRows(Integer maxRows)

The maximum number of rows to query. The value is set on the underlying JdbcPollingChannelAdapter. Also used to check before producing reply: if result has only one item and maxRows is not set or configured to 1, only that item is returned. Otherwise, the whole list. If not specified this value will default to 1. This parameter is only applicable if a selectQuery was provided. Null values are not permitted.

Parameters:

maxRows - the number of rows to select. Must not be null.

Since:

5.1

• JdbcPollingChannelAdapter.setMaxRows(int)

setKeysGenerated

public void setKeysGenerated(boolean keysGenerated)

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

Parameters:

keysGenerated - the flag value to set

setRequestSqlParameterSourceFactory

public void setRequestSqlParameterSourceFactory(SqlParameterSourceFactory sqlParameterSourceFactory)

Set a SqlParameterSourceFactory for update query.

Parameters:

sqlParameterSourceFactory - the SqlParameterSourceFactory to use.

setRequestPreparedStatementSetter

public void setRequestPreparedStatementSetter(MessagePreparedStatementSetter requestPreparedStatementSetter)

Set a MessagePreparedStatementSetter for update query.

Parameters:

requestPreparedStatementSetter - the MessagePreparedStatementSetter to use.

setReplySqlParameterSourceFactory

public void setReplySqlParameterSourceFactory(SqlParameterSourceFactory sqlParameterSourceFactory)

/** Set a SqlParameterSourceFactory for select query.

Parameters:

sqlParameterSourceFactory - the SqlParameterSourceFactory to use.

setRowMapper

public void setRowMapper(RowMapper<?> rowMapper)

Set a select result RowMapper.

Parameters:

rowMapper - the RowMapper to use.

getComponentType

public String getComponentType()

Description copied from class: IntegrationObjectSupport

Subclasses may implement this method to provide component type information.

Specified by:

getComponentType in interface NamedComponent

Overrides:

getComponentType in class MessageHandlerSupport

doInit

protected void doInit()

Overrides:

doInit in class AbstractReplyProducingMessageHandler

handleRequestMessage

protected 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

Parameters:

requestMessage - The request message.

Returns:

The result of handling the message, or null.
