使用springfox 集成swagger 与spring mvc

1. 建立一个maven 模块 将springfox相关的配置都配置在一个单独的api模块中，能够把这个模块当成web应用跑起来。

<!-- Include a swagger configuration-->
<bean name="/applicationSwaggerConfig" class="cn.com.yixun.doc.swagger.Swagger2Spring"/>

启动项目以后打开网址，{项目地址}/swagger-ui.html 就能够访问了。

后记：因为swagger对项目的侵入性比较强，能够考虑把注解写在接口上。
