① WebWork2.2.1とSeasarをつなげてみる。

1. ObjectFactoryを継承したクラスを作る

com.opensymphony.xwork.ObjectFactoryを継承したクラスを作る。その際com.opensymphony.webwork.util.ObjectFactoryInitializableをimplementsする

public class S2ObjectFactory extends ObjectFactory implements ObjectFactoryInitializable {

    private S2Container container = null;

    /**
     * @see com.opensymphony.webwork.util.ObjectFactoryInitializable#init(javax.servlet.ServletContext)
     */
    public void init(ServletContext servletContext) {
        this.container = SingletonS2ContainerFactory.getContainer();
    }

    /**
     * @see com.opensymphony.xwork.ObjectFactory#buildAction(java.lang.String, java.lang.String,
     * com.opensymphony.xwork.config.entities.ActionConfig, java.util.Map)
     */
    public Object buildAction(String actionName, String namespace, ActionConfig config, Map extraContext) throws Exception {
        return buildBean(config.getClassName(), extraContext);
    }

    /**
     * @see com.opensymphony.xwork.ObjectFactory#buildBean(java.lang.Class, java.util.Map)
     */
    public Object buildBean(Class clazz, Map extraContext) throws Exception {
        return getComponent(clazz);
    }

    /**
     * @see com.opensymphony.xwork.ObjectFactory#buildBean(java.lang.String, java.util.Map)
     */
    public Object buildBean(String className, Map extraContext) throws Exception {
        return getComponent(className);
    }

    private Object getComponent(Object targetClass) throws InstantiationException, IllegalAccessException,
            ClassNotFoundException {
        if (this.container.hasComponentDef(targetClass)) {
            return this.container.getComponent(targetClass);
        }
        // 指定されたクラスがない場合
        // 実際はgetClassInstanceメソッドでContinuation対応がなれているがとりあえず未対応
        Class clazz = null;
        if (targetClass instanceof Class) {
            clazz = (Class) targetClass;
        } else if (targetClass instanceof String) {
            clazz = Class.forName((String) targetClass);
        }
        if (clazz == null) {
            throw new ClassNotFoundException(targetClass.toString());
        }
        return clazz.newInstance();
    }
}

2. webwork.properties

webwork.propertiesに上記で作ったObjectFactoryを設定する

webwork.objectFactory = jp.co.ysd.webwork.seaser.S2ObjectFactory
