CDIコンテナにSeasar2のコンポーネントを移す (その２)

前回の、CDIコンテナにSeasar2のコンポーネントを移す (その１)に書いた記事の続きです。

サーバーの起動処理（例）

import org.eclipse.jetty.server.Server;
import org.glassfish.jersey.jetty.JettyHttpContainerFactory;

public class HogeMain {
    public static void main(String[] args) {
        HogeConfig config = new HogeConfig();
        Server server = JettyHttpContainerFactory.createServer(URI, config, false);
        server.start();
    }
}

S2コンテナの中身を CDIコンテナに移す処理のサンプル

処理の説明はまた今度。。

import org.glassfish.jersey.server.ResourceConfig;

public class HogeConfig extends ResourceConfig {

    public HogeConfig() {

        packages(this.getClass().getPackage().getName());

        register(new AbstractBinder() {
            @Override
            protected void configure() {
                for (ComponentDef def : getComponentDefs()) {
                    Class<?> clazz = def.getComponentClass();
                    String name = def.getComponentName();
                    Descriptor descriptor;
                    if (InstanceDef.SINGLETON_NAME.equals(def.getInstanceDef().getName())
                            || InstanceDef.APPLICATION_NAME.equals(def.getInstanceDef().getName())) {
                        descriptor = BuilderHelper.createConstantDescriptor(def.getComponent(), name,
                                clazz.getInterfaces());
                    } else {
                        DescriptorBuilder builder = BuilderHelper.link(clazz).named(name).in(PerLookup.class);
                        for (Class<?> contract : clazz.getInterfaces()) {
                            builder = builder.to(contract);
                        }
                        descriptor = builder.build();
                    }
                    this.bind(descriptor);
                }
            }

            private List<ComponentDef> getComponentDefs() {
                S2Container container = S2ContainerFactory.create();
                container.init();
                List<ComponentDef> componentDefList = new ArrayList<ComponentDef>();
                componentDefList.addAll(getComponentDefs(container));
                return componentDefList;
            }

            private Set<ComponentDef> getComponentDefs(S2Container container) {
                Set<ComponentDef> componentDefSet = new LinkedHashSet<ComponentDef>();
                for (int i = 0; i < container.getComponentDefSize(); i++) {
                    ComponentDef componentDef = container.getComponentDef(i);
                    componentDefSet.add(componentDef);
                }
                for (int i = 0; i < container.getChildSize(); i++) {
                    S2Container child = container.getChild(i);
                    componentDefSet.addAll(getComponentDefs(child));
                }
                return componentDefSet;
            }
        });
    }
}

続く

・・・かも。。
