前言
swagger,中文“拽”的意思。它是一个功能强大的api框架，它的集成非常简单，不仅提供了在线文档的查阅，
而且还提供了在线文档的测试。另外swagger很容易构建restful风格的api。
Swagger是一组围绕OpenAPI规范构建的开源工具，可帮助设计、构建、记录和使用REST API。
简单说下，它的出现就是为了方便进行测试后台的restful形式的接口，实现动态的更新，当我们在后台的接口
修改了后，swagger可以实现自动的更新，而不需要认为的维护这个接口进行测试。
swagger通过注解表明该接口会生成文档，包括接口名、请求方法、参数、返回信息的等等。
<dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>2.7.0</version> </dependency> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> <version>2.7.0</version> </dependency>
通过@Configuration注解，表明它是一个配置类，@EnableSwagger2开启swagger2。
apiINfo()配置一些基本的信息。apis()指定扫描的包会生成文档。
再通过createRestApi函数创建Docket的Bean之后，apiInfo()用来创建该Api的基本信息（这些基本信息会
展现在文档页面中）。select()函数返回一个ApiSelectorBuilder实例用来控制哪些接口暴露给Swagger来
展现，本例采用指定扫描的包路径来定义，Swagger会扫描该包下所有Controller定义的API，并产生文档内容
（除了被@ApiIgnore指定的请求）。

描述主要来源于函数等命名产生，对用户并不友好，我们通常需要自己增加一些说明来丰富文档内容。
如下所示，我们通过@ApiOperation注解来给API增加说明、通过@ApiImplicitParams、@ApiImplicitParam
注解来给参数增加说明。
