7.8. Bean Metadata Builder
When using the Microcontainer in your code, use
BeanMetaDataBuilder to create and configure your bean metadata.
Example 7.17. BeanMetaDataBuilder
<bean name="BuilderUtil" class="org.jboss.demos.ioc.builder.BuilderUtil"/>
<bean name="BuilderExampleHolder" class="org.jboss.demos.ioc.builder.BuilderExampleHolder">
<constructor>
<parameter><inject bean="BUExample"/></parameter>
</constructor>
</bean>
Using this concept, you don't expose your code to any Microcontainer implementation details.
public class BuilderUtil {
private KernelController controller;
@Constructor
public BuilderUtil(@Inject(bean = KernelConstants.KERNEL_CONTROLLER_NAME) KernelController controller) {
this.controller = controller;
}
public void create() throws Throwable {
BeanMetaDataBuilder builder = BeanMetaDataBuilder.createBuilder("BUExample", BuilderExample.class.getName());
builder.addStartParameter(Kernel.class.getName(), builder.createInject(KernelConstants.KERNEL_NAME));
controller.install(builder.getBeanMetaData());
}
public void destroy() {
controller.uninstall("BUExample");
}
}
