Class UserCredentialsConnectionFactoryAdapter

java.lang.Object
org.springframework.jms.connection.UserCredentialsConnectionFactoryAdapter
All Implemented Interfaces:
ConnectionFactory, QueueConnectionFactory, TopicConnectionFactory, InitializingBean

public class UserCredentialsConnectionFactoryAdapter extends Object implements ConnectionFactory, QueueConnectionFactory, TopicConnectionFactory, InitializingBean
An adapter for a target JMS ConnectionFactory, applying the given user credentials to every standard methods that can also be used with authentication, this createConnection() and createContext(). In other words, it is implicitly invoking createConnection(username, password) or createContext(username, password)} 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 user credentials configured. Client code can work with the ConnectionFactory without passing in username and password on every createConnection() and createContext() 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/jms/mycf"/>
 </bean>

 <bean id="myConnectionFactory" class="org.springframework.jms.connection.UserCredentialsConnectionFactoryAdapter">
   <property name="targetConnectionFactory" ref="myTargetConnectionFactory"/>
   <property name="username" value="myusername"/>
   <property name="password" value="mypassword"/>
 </bean>

If the "username" is empty, this proxy will simply delegate to the standard createConnection() or createContext() method of the target ConnectionFactory. This can be used to keep a UserCredentialsConnectionFactoryAdapter bean definition just for the option of implicitly passing in user credentials if the particular target ConnectionFactory requires it.

As of Spring Framework 5, this class delegates JMS 2.0 JMSContext calls and therefore requires the JMS 2.0 API to be present at runtime. It may nevertheless run against a JMS 1.1 driver (bound to the JMS 2.0 API) as long as no actual JMS 2.0 calls are triggered by the application's setup.
