/**
 * 事件定义
 */
public abstract class AbstractEvent extends EventObject{

	/**
	 *
	 */
	private static final long serialVersionUID = 977722347679465568L;

	public  AbstractEvent(Object source) {
		super(source);
	}


}

2.定义业务事件

public class BizEvent extends AbstractEvent {
    public bizEvent(DetailModel DetailModel) {
        super(DetailModel);
    }
}

3.定义事件监听基础接口

public interface IEventListener extends EventListener {
	
	void processEventOccurred(AbstractEvent evt);

}

4.定义业务监听

public class BizListener implements IEventListener {

    /**
     * key: id
     * value: BizModel
     */
    private static Map<String, BizModel> CASCADE_APPLY_DETAIL_CACHE = new ConcurrentHashMap<String,BizModel>();

    public BizListener(EventRegister register) {
        regis
