Class JmsGatewaySupport

java.lang.Object

org.springframework.jms.core.support.JmsGatewaySupport

All Implemented Interfaces:

org.springframework.beans.factory.InitializingBean

public abstract class JmsGatewaySupport
extends Object
implements org.springframework.beans.factory.InitializingBean

Convenient super class for application classes that need JMS access.

Requires a ConnectionFactory or a JmsTemplate instance to be set. It will create its own JmsTemplate if a ConnectionFactory is passed in. A custom JmsTemplate instance can be created for a given ConnectionFactory through overriding the createJmsTemplate(javax.jms.ConnectionFactory) method.

Since:

1.1.1

Method Detail

setConnectionFactory

public final void setConnectionFactory(javax.jms.ConnectionFactory connectionFactory)

Set the JMS connection factory to be used by the gateway. Will automatically create a JmsTemplate for the given ConnectionFactory.

See Also:

createJmsTemplate(javax.jms.ConnectionFactory), setConnectionFactory(javax.jms.ConnectionFactory)

createJmsTemplate

protected JmsTemplate createJmsTemplate(javax.jms.ConnectionFactory connectionFactory)

Create a JmsTemplate for the given ConnectionFactory. Only invoked if populating the gateway with a ConnectionFactory reference.

Can be overridden in subclasses to provide a JmsTemplate instance with a different configuration.

Parameters:

connectionFactory - the JMS ConnectionFactory to create a JmsTemplate for

Returns:

the new JmsTemplate instance

See Also:

setConnectionFactory(javax.jms.ConnectionFactory)

getConnectionFactory

public final javax.jms.ConnectionFactory getConnectionFactory()

Return the JMS ConnectionFactory used by the gateway.

setJmsTemplate

public final void setJmsTemplate(JmsTemplate jmsTemplate)

Set the JmsTemplate for the gateway.

See Also:

setConnectionFactory(javax.jms.ConnectionFactory)

getJmsTemplate

public final JmsTemplate getJmsTemplate()

Return the JmsTemplate for the gateway.

afterPropertiesSet

public final void afterPropertiesSet()
                              throws IllegalArgumentException,
                                     org.springframework.beans.factory.BeanInitializationException

Specified by:

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

Throws:

IllegalArgumentException

org.springframework.beans.factory.BeanInitializationException

initGateway

protected void initGateway()
                    throws Exception

Subclasses can override this for custom initialization behavior. Gets called after population of this instance's bean properties.

Throws:

Exception - if initialization fails
