Adding Spring to the mix (GWT, Maven, Eclipse)

Great tutorial for adding Spring into the mix of my last post.

http://www.springbyexample.org/examples/simple-gwt-spring-webapp-reference.html

The tutorial doesn't cover everything though, make sure to take a look at the sample application

svn co http://svn.springbyexample.org/web/simple-gwt-webapp/tags/1.0/ simple-gwt-webapp

Constants in Spring Context

Found an easy way to include a constant declared in some random Java file into the context file.

http://www.unicon.net/node/601

<bean id="Context" class="javax.naming.InitialContext"> 
    <constructor-arg> 
        <util:map id="jmsProperties" map-class="java.util.Hashtable"> 
            <entry> 
                <key><util:constant static-field="javax.naming.Context.INITIAL_CONTEXT_FACTORY"/></key> 
                <value>org.apache.activemq.jndi.ActiveMQInitialContextFactory</value> 
            </entry> 
            <entry> 
                <key><util:constant static-field="javax.naming.Context.PROVIDER_URL"/></key> 
                <value>tcp://localhost:61616</value> 
            </entry> 
        </util:map> 
    </constructor-arg> 
</bean>

Create custom Spring injected Dozer BeanFactory

Autowiring objects not instantiated by the Spring Framework

In order to enabled autowiring capabilities, add the following properties to the beans element.
xsi:schemaLocation="http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"
xmlns:context="http://www.springframework.org/schema/context"

And make sure this line is included within the beans element
<context:annotation-config />

Next, in your code, get an instance of AutowireCapableBeanFactory.

Hint: Subclasses of AbstractApplicationContext have a getAutowireCapableBeanFactory, just one way to get such an instance.

Finally call the autowireBean(MyObject) method and like magic, so long as the annotations are correct, Spring will inject the correct instances.
