AOP
org.springframework.aop.TargetSource that provides
configurable JNDI lookups for getTarget() calls.
Can be used as alternative to
JndiObjectFactoryBean , to allow for
relocating a JNDI object lazily or for each operation (see "lookupOnStartup"
and "cache" properties). This is particularly useful during development, as it
allows for hot restarting of the JNDI server (for example, a remote JMS server).
Example:
<bean id="queueConnectionFactoryTarget" class="org.springframework.jndi.JndiObjectTargetSource">
<property name="jndiName" value="JmsQueueConnectionFactory"/>
<property name="lookupOnStartup" value="false"/>
</bean>
<bean id="queueConnectionFactory" class="org.springframework.aop.framework.ProxyFactoryBean">
<property name="proxyInterfaces" value="javax.jms.QueueConnectionFactory"/>
<property name="targetSource" ref="queueConnectionFactoryTarget"/>
</bean>
A createQueueConnection call on the "queueConnectionFactory" proxy will
cause a lazy JNDI lookup for "JmsQueueConnectionFactory" and a subsequent delegating
call to the retrieved QueueConnectionFactory's createQueueConnection.
Alternatively, use a
JndiObjectFactoryBean with a "proxyInterface".
"lookupOnStartup" and "cache" can then be specified on the JndiObjectFactoryBean,
creating a JndiObjectTargetSource underneath (instead of defining separate
ProxyFactoryBean and JndiObjectTargetSource beans).
