<content type="html"><![CDATA[<p><img src="http://cdn.tiimor.cn/images/GreenDao.png" alt="GreenDao"></p><p>GreenDao 是一个将对象映射到 SQLite 数据库中的轻量且快速的 ORM 解决方案。它的本质就是提供一个面向对象的接口，使得开发者更加方便地将数据存储到数据库SQLite之中。我们只需要定义数据模型，GreenDao就会为我们生成实体类以及DAOs(data access objects)，（在3.0之后不需要我们编写generator而是编写实体类并添加注解，GreenDao会为我们生成schema，以及DAOs）从而避免了开发者编写较多枯燥的数据存储和加载的代码。</p><a id="more"></a><hr><blockquote><ul><li><a

<p>GreenDao 是一个将对象映射到 SQLite 数据库中的轻量且快速的 ORM 解决方案。它的本质就是提供一个面向对象的接口，使得开发者更加方便地将数据存储到数据库SQLite之中。我们只需要定义数据模型，GreenDao就会为我们生成实体类以及DAOs(data access objects)，（在3.0之后不需要我们编写generator而是编写实体类并添加注解，GreenDao会为我们生成schema，以及DAOs）从而避免了开发者编写较多枯燥的数据存储和加载的代码。</p>

App出现bug的时候，甚至仅仅是修改一行代码，都要重新发布新版本对bug进行修复，这样带来的缺点是明显的，需要用户重新升级app，覆盖率太慢，成本太高。所以就出现了热修复技术，通过打补丁的方式，通过从服务器下载补丁包，然后对有问题的类中出问题的方法，进行替换，优点是用户无感知修复，无需下载新的应用，代价小。对比其他的热修复方案，<strong>来耍一耍阿里-Sophix</strong>

<p>以往当Android App出现bug的时候，甚至仅仅是修改一行代码，都要重新发布新版本对bug进行修复，这样带来的缺点是明显的，需要用户重新升级app，覆盖率太慢，成本太高。所以就出现了热修复技术，通过打补丁的方式，通过从服务器下载补丁包，然后对有问题的类中出问题的方法，进行替换，优点是用户无感知修复，无需下载新的应用，代价小。对比其他的热修复方案，<strong>来耍一耍阿里-Sophix</strong> 。</p>
