Swagger2 3.0由于新增了Starter 因此可以直接使用starter方式
<!-- https://mvnrepository.com/artifact/io.springfox/springfox-boot-starter -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-boot-starter</artifactId>
            <version>3.0.0</version>
        </dependency>
在没有starter前 一般都是引入以下依赖  两个依赖的版本最好一致，避免出现冲突
<!--        &lt;!&ndash; https://mvnrepository.com/artifact/io.springfox/springfox-swagger2 &ndash;&gt;-->
<!--        <dependency>-->
<!--            <groupId>io.springfox</groupId>-->
<!--            <artifactId>springfox-swagger2</artifactId>-->
<!--            <version>3.0.0</version>-->
<!--        </dependency>-->
<!--        <dependency>-->
<!--            <groupId>io.springfox</groupId>-->
<!--            <artifactId>springfox-swagger-ui</artifactId>-->
<!--            <version>3.0.0</version>-->
<!--        </dependency>-->

new Docket(DocumentationType documentationType); 有参构造 参数 对应为 swagger版本

.apiInfo(api()) return —>>>Docket ApiInfoBuilder()

.select() —>>> return ApiSelectorBuilder

ApiSelectorBuilder .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))
