Mybatis Generator tool 在我们开启一个新项目的研发后,通常要编写很多的 entity/pojo/dto/mapper/dao... , 大多研发兄弟们都会抱怨,为什么我要重复写 CRUD ? 我们为了避免编写一些不必要的重复代码,这节给大家介绍介绍使用一个开源工具,来帮助我们从这种简单枯燥的编码中解救出来。 隆重有请: MyBatis通用Mapper4 通用Mapper都可以极大的方便开发人员。可以随意的按照自己的需要选择通用方法,还可以很方便的开发自己的通用方法。 极其方便的使用 MyBatis单表 的增删改查。 支持单表操作,不支持通用的多表联合查询。 通用 Mapper 支持 Mybatis-3.2.4 及以上版本。 Tips: 各位技术同仁一定要有版本意识哦~ Let's code!

Thanks The "R4" image will only work on 4-inch iPhone running iOS 7 or later. On older version of iOS it will use 2x image. Example. If you

Magento: how to get the price of a product with catalog rules applied

时光毁灭记忆、已成空白 提交于 2019-11-29 00:24:24
问题 I'm developing a script (external to Magento, not a module) which aims to output a text list of all available products, their prices and some other attributes. However, catalog price rules don't seem to be applied to product prices. If I use any of the following: $_product->getPrice() $_product->getFinalPrice() I get the normal price (without rules being applied). If I use: $_product->getSpecialPrice() I get null unless the product actually has a special price inserted in the product itself

Using Lucene to count results in categories

女生的网名这么多〃 提交于 2019-11-28 19:03:57
问题 I am trying to use Lucene Java 2.3.2 to implement search on a catalog of products. Apart from the regular fields for a product, there is field called 'Category'. A product can fall in multiple categories. Currently, I use FilteredQuery to search for the same search term with every Category to get the number of results per category. This results in 20-30 internal search calls per query to display the results. This is slowing down the search considerably. Is there a faster way of achieving the

Magento products by categories

六眼飞鱼酱① 提交于 2019-11-27 19:51:53
Does anyone know how I can get a list of products belonging to a specific category from within a view file in Magento ? mivec You can use magento object to filter. Example: $categoryId = 123; // a category id that you can get from admin $category = Mage::getModel('catalog/category')->load($categoryId); $products = Mage::getModel('catalog/product') ->getCollection() ->addCategoryFilter($category) ->load(); print_r($products); It all depends on which view you're in. ;-) First off, I hope you stayed within your template set (default in my example). Use this as an example : <?php $_cat = $this-

What are the JPA @Table annotation “catalog” and “schema” variables used for?

偶尔善良 提交于 2019-11-27 12:59:54
问题 Why are these important, what effect do they have on the database at hand? Isn't the "schema" already decided at that point, as it exists in the database? What exactly is a "catalog"? What kind of variable/input is the JPA catalog field expecting? Also, same question for the "schema" field. 回答1: Catalogs and schemas are "namespaces" that you define on the server side of the database. Some databases contains schemas, some contains catalogs, and some contains both. When logging in with a
