public class ConnectionSpecConnectionFactoryAdapter
An adapter for a target CCI ConnectionFactory
,
applying the given ConnectionSpec to every standard getConnection()
call, that is, implicitly invoking getConnection(ConnectionSpec)
on the target. All other methods simply delegate to the corresponding methods
of the target ConnectionFactory.
Can be used to proxy a target JNDI ConnectionFactory that does not have a
ConnectionSpec configured. Client code can work with the ConnectionFactory
without passing in a ConnectionSpec on every getConnection()
call.
In the following example, client code can simply transparently work with the preconfigured "myConnectionFactory", implicitly accessing "myTargetConnectionFactory" with the specified user credentials.
<bean id="myTargetConnectionFactory" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiName" value="java:comp/env/cci/mycf"/> </bean> <bean id="myConnectionFactory" class="org.springframework.jca.cci.connection.ConnectionSpecConnectionFactoryAdapter"> <property name="targetConnectionFactory" ref="myTargetConnectionFactory"/> <property name="connectionSpec"> <bean class="your.resource.adapter.ConnectionSpecImpl"> <property name="username" value="myusername"/> <property name="password" value="mypassword"/> </bean> </property> </bean>
If the "connectionSpec" is empty, this proxy will simply delegate to the
standard getConnection()
method of the target ConnectionFactory.
This can be used to keep a UserCredentialsConnectionFactoryAdapter bean definition
just for the option of implicitly passing in a ConnectionSpec if the
particular target ConnectionFactory requires it.
