Spring Boot 集成 Swagger2 與配置 OAuth2.0 授權

Spring Boot 集成 Swagger2 很簡單，由於接口采用了OAuth2.0 & JWT 協議做了安全驗證，使用過程中也遇到了很多小的問題，多次嘗試下述配置可以正常使用。

Maven

配置 Resource Owner Password Credentials 模式的 Client

Test

問題：

swagger-2.9.1 /csrf is 404 問題 

A：這個問題在 2.9.x 版本中有(https://github.com/springfox/springfox/issues/2603) ，暫時還沒有找到好的解決方案，回退到 2.8.0 版本。

配置 ApiKey 后 HTTP 頭 Authorization: Bearer {THE TOKEN} 不生效問題

A：2.7.x 版本沒有問題(https://github.com/springfox/springfox/issues/1812)

@Bean
    public SecurityScheme apiKey() {
        return new ApiKey(HttpHeaders.AUTHORIZATION, "apiKey", "header");
    }

后面使用了 OAuth2.0 協議在 2.8.0 版本中無問題。
