Constructor Detail

StoredProcOutboundGateway

public StoredProcOutboundGateway(StoredProcExecutor storedProcExecutor)

Constructor taking StoredProcExecutor.

Parameters:

storedProcExecutor - Must not be null.

Method Detail

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 AbstractMessageHandler

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.

setExpectSingleResult

public void setExpectSingleResult(boolean expectSingleResult)

This parameter indicates that only one result object shall be returned from the Stored Procedure/Function Call. If set to true, a resultMap that contains only 1 element, will have that 1 element extracted and returned as payload. If the resultMap contains more than 1 element and expectSingleResult is true, then a MessagingException is thrown. Otherwise the complete resultMap is returned as the Message payload. Important Note: Several databases such as H2 are not fully supported. The H2 database, for example, does not fully support the CallableStatement semantics and when executing function calls against H2, a result list is returned rather than a single value. Therefore, even if you set expectSingleResult = true, you may end up with a collection being returned.

Parameters:

expectSingleResult - true if a single result is expected.
