JndiObjectTargetSource()
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>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).
