Springfox2.6.1+SpringMVC+Swagger2配置手记
最近一直在捣鼓Swagger的事情，起初使用Swagger1可以配个 swagger-springmvc成功，但是它配合SpringMVC项目如果是一个上传文件就不太友好了，无法展示上传文件的按钮，所以有上传文件，图片的api就无法使用了！！！！
百度了好一阵子，在万能的stackoverflow上终于得到答案，国内的搜索网站贴吧这点儿真的有些逊色了，没有关于这方面的解决方案，还是靠我微薄的英语知识搜索到的，原来 swagger-springmvc1.0.2（最新的）已经过时了，已经被springfox取代了 ！！！！！！！！
好吧，伐开心！好不容易熬了几个通宵配置起来的swagger就这样夭折了。
那就继续研究springfox的swagger配置；
现在时刻的当前版本是springfox2.6.1；果断maven下来
<dependency>
<groupId>io.springfoxgroupId>
<artifactId>springfox-swagger2artifactId>
<version>${springfox.version}version>
dependency>
<dependency>
<groupId>io.springfoxgroupId>
<artifactId>springfox-swagger-uiartifactId>
<version>${springfox.version}version>
dependency>在然后写配置：
@Configuration // 配置注解
@EnableWebMvc // 启用Mvc //非springboot框架需要引入注解@EnableWebMvc
@EnableSwagger2 // 启用Swagger2，毕竟SpringFox的核心依旧是Swagger
// @ComponentScan(basePackages = "com.june.controller.back.common.*")//然而并没有卵用
public class SwaggerConfig extends WebMvcConfigurerAdapter {
@Bean
public Docket customDocket() {
return new Docket(DocumentationType.SWAGGER_2).select()// 选择哪些路径和API会生成document
.apis(RequestHandlerSelectors.any())// 对所有api进行监控
.paths(PathSelectors.any())// 对所有路径进行监控
.build().apiInfo(apiInfo());
}// */
private ApiInfo apiInfo() {
return new ApiInfo(PROJ, DESC, VERS, SERV, new Contact(NAME, URL, CONT), LICS, L_URL);
}
}小弟的所有配置都是参考了这位CSDN的仁兄的博客
好吧开开心心的（其实并不开心，工作好好的，就今天公司说辞就辞，把一位一起工作的同事给辞掉了，很震惊也很愤怒，更为自己考虑考虑），
然后运行，心想这个应该不会有问题了，因为以前的swagger1已经配置的very very good了，至少运行是没有任何问题的，结果呵呵哒！

解决问题，在这个贴最后发现一位仁兄这样总结的：
a work around is to rollback to springfox-swagger2 2.5.0 .呵呵，现在正在研究 spring2.5.0了……有成果了在了分享！
