public class JndiObjectTargetSource extends JndiObjectLocator implements org.springframework.aop.TargetSource
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).

Can be turned off to allow for late availability of the JNDI object. In this case, the JNDI object will be fetched on first access.
setCache(boolean)public void setCache(boolean cache)
Can be turned off to allow for hot redeployment of JNDI objects. In this case, the JNDI object will be fetched for each invocation.
