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

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).

public JndiObjectTargetSource()

方法详细资料

setLookupOnStartup

public void setLookupOnStartup(boolean lookupOnStartup)

Set whether to look up the JNDI object on startup. Default is "true".

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.

另请参阅:

setCache(boolean)

setCache

public void setCache(boolean cache)

Set whether to cache the JNDI object once it has been located. Default is "true".

Can be turned off to allow for hot redeployment of JNDI objects. In this case, the JNDI object will be fetched for each invocation.
