Swagger笔记之Swagger2配置

@TOC

什么是 Swagger？

Swagger是一组围绕 OpenAPI 规范构建的开源工具，可帮助您设计、构建、记录和使用 REST API。主要的 Swagger 工具包括：

Swagger Editor – 基于浏览器的编辑器，您可以在其中编写 OpenAPI 规范。
Swagger UI – 将 OpenAPI 规范呈现为交互式 API 文档。

swagger2于17年停止维护，现在最新的版本为 Swagger3（Open Api3）。

依赖引入

我们可以去 mvnrepository（maven中央仓库） 搜索版本，但是建议不要用最新版

        <!-- swagger2  -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>

详细配置

配置文件加上@EnableSwagger2、@Configuration 会自动开启配置，启动类不需要加任何注解

}

swagger资源访问路径加入白名单

- /swagger-ui.html
- /doc.html
- /swagger-resources/**
- /v2/api-docs

访问路径：

http:IP:端口号/swagger-ui.html 原生地址
http:IP:端口号/doc.html bootStrap-UI地址

小技巧：

不建议使用swagger原生页面设置权限，建议使用doc页面设置token，搜索接口更方便
