MVC层和持久层衔接一个比较重大的调整：

        	//如果是以POST方式请求数据，则获取Detach状态的对象，其他则保留Session方式以便获取Lazy属性
        	HttpServletRequest request = this.getRequest();
        	if(request.getMethod().equalsIgnoreCase("POST")){
        		bindingEntity = getEntityService().findDetachedOne(getId());
        	}else{
        		bindingEntity = getEntityService().findOne(getId());
        	}
