<h1 id="210-211">2.1.0 升级 2.1.1指导</h1>
<h2 id="zero-config">使用 zero config 服务发现的场景</h2>
<p>zero config 服务发现是 2.1.0 新增的功能， 2.1.1 对发现过程中交换的报文格式进行了优化。 如果使用了 zero config
功能， 升级到 2.1.1 的时候，需要对相关服务也同时做升级， 否则无法发现实例。 </p>
<h2 id="swagger-generator-spring-data-page">使用 <code>swagger-generator-spring-data</code> 扩展，支持 <code>Page</code> 接口参数的场景</h2>
<p>由于 <code>spring-data</code> 不同的版本的接口差异很大， 这个模块支持的扩展对应的 <code>spring-data</code> 版本为
<code>2.1.9.RELEASE</code>， 并且对于 <code>Sort</code> 接口的序列化没完整支持。 开发者如果使用 <code>spring-data</code>
的不同版本， 或者需要对 <code>spring-data</code> 的不同接口提供扩展支持， 需要在项目中引入需要的
版本， 并参考 <code>swagger-generator-spring-data</code> 实现自己的扩展，而不是直接依赖于
<code>swagger-generator-spring-data</code> 模块。 </p>
