5.5. Using Custom Adapters

In Chapters 7 and 9, you will learn about custom adapters. In this brief section, I will illustrate an example that shows how you can configure a custom adapter.

Gilead, a custom Hibernate adapter that you will learn about in Chapter 7, can be configured in remoting-config.xml like so:

<adapters>
    <adapter-definition id="persistent-adapter"
        class="net.sf.gilead.blazeds.adapter.PersistentAdapter">
        <properties>
            <persistence-factory>
                <class>net.sf.gilead.sample.server.ApplicationContext</class>
                <singleton>true</singleton>
                <method>getSessionFactory</method>
            </persistence-factory>
        </properties>
    </adapter-definition>
</adapters>

Using the Spring BlazeDS adapter JSON format is used to configure parameters on a custom adapter. The preceding configuration under Spring BlazeDS would be:

<bean id="persistent-adapter"
class="org.springframework.flex.core.ManageableComponentFactoryBean">
    <constructor-arg value="net.sf.gilead.blazeds.adapter.PersistentAdapter"/>
    <property name="properties">
        <value>
            {"persistenceFactory" :
                { "class" :
                  "net.sf.gilead.sample.server.ApplicationContext",
                  "singleton" : "true",
                  "method": "getSessionFactory"
                }
            }
        </value>
    </property>
</bean>

The Spring BlazeDS configuration for custom adapters configures these adapters using the org.springframework.flex.core.ManageableComponentFactoryBean.
