## org.springframework.jms.connection
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 `createConnection()` call, that is, implicitly invoking `createConnection(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()` 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()` 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.

Constructor Detail

### UserCredentialsConnectionFactoryAdapter

    public UserCredentialsConnectionFactoryAdapter()

Method Detail

### setTargetConnectionFactory

    public void setTargetConnectionFactory(ConnectionFactory targetConnectionFactory)

  Set the target ConnectionFactory that this ConnectionFactory should delegate to.

### setUsername

    public void setUsername(String username)

  Set the username that this adapter should use for retrieving Connections. Default is no specific user.

### setPassword

    public void setPassword(String password)

  Set the password that this adapter should use for retrieving Connections. Default is no specific password.

### afterPropertiesSet

    public void afterPropertiesSet()

  Description copied from interface: `InitializingBean`
  Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

  This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

  Specified by:
    `afterPropertiesSet` in interface `InitializingBean`

### setCredentialsForCurrentThread

    public void setCredentialsForCurrentThread(String username,
                                               String password)

  Set user credententials for this proxy and the current thread. The given username and password will be applied to all subsequent `createConnection()` calls on this ConnectionFactory proxy.

  This will override any statically specified user credentials, that is, values of the "username" and "password" bean properties.

  Parameters:
    `username` - the username to apply
    `password` - the password to apply
  See Also:
    `removeCredentialsFromCurrentThread()`

### removeCredentialsFromCurrentThread

    public void removeCredentialsFromCurrentThread()

  Remove any user credentials for this proxy from the current thread. Statically specified user credentials apply again afterwards.

    `setCredentialsForCurrentThread(java.lang.String, java.lang.String)`
