上一级下一级的排序

还可以再抽象，先暂时这样，方便看：

     * @param property
     * @param model
     * @return
     */
    @RequestMapping(value = "/down", method = RequestMethod.POST)

    	property = propertyService.findBySortCode(property.getSortCode());
    	String parentCode = property.getSortCode().substring(0, property.getSortCode().lastIndexOf("-"));
        List<Property> properties = propertyService.findChild(parentCode);
        int index = properties.indexOf(property);
        Property nextProperty = properties.get(index+1); 
        long sortId = property.getSortId();

        property.setSortId(nextSortId);

        propertyService.update(property);
        propertyService.update(nextProperty);
        return "SUCCESS";
    }
