org.springframework.jms.connection
Class DelegatingConnectionFactory

java.lang.Object
  org.springframework.jms.connection.DelegatingConnectionFactory

All Implemented Interfaces:

ConnectionFactory, QueueConnectionFactory, TopicConnectionFactory, InitializingBean, SmartConnectionFactory

---

public class DelegatingConnectionFactory
extends Object
implements SmartConnectionFactory, QueueConnectionFactory, TopicConnectionFactory, InitializingBean

ConnectionFactory implementation that delegates all calls to a given target ConnectionFactory.

This class allows for being subclassed, with subclasses overriding only those methods (such as createConnection()) that should not simply delegate to the target ConnectionFactory.

Can also be defined as-is, wrapping a specific target ConnectionFactory, using the "shouldStopConnections" flag to indicate whether Connections obtained from the target factory are supposed to be stopped before closed. The latter may be necessary for some connection pools that simply return released connections to the pool, not stopping them while they sit in the pool.

Since:

2.0.2

Juergen Hoeller

Constructor Detail

DelegatingConnectionFactory

public DelegatingConnectionFactory()

Method Detail

setTargetConnectionFactory

public void setTargetConnectionFactory(ConnectionFactory targetConnectionFactory)

Set the target ConnectionFactory that this ConnectionFactory should delegate to.

---

getTargetConnectionFactory

public ConnectionFactory getTargetConnectionFactory()

Return the target ConnectionFactory that this ConnectionFactory delegates to.

---

setShouldStopConnections

public void setShouldStopConnections(boolean shouldStopConnections)

Indicate whether Connections obtained from the target factory are supposed to be stopped before closed ("true") or simply closed ("false"). The latter may be necessary for some connection pools that simply return released connections to the pool, not stopping them while they sit in the pool.

Default is "false", simply closing Connections.

afterPropertiesSet

public void afterPropertiesSet()

Description copied from interface: InitializingBean

Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

Specified by:

afterPropertiesSet in interface InitializingBean
