# Swagger2 SpringMVC集成(非SpringBoot)
Swgger
做过手机端接口的同学们都有过历史的经历,写完一个接口之后,Junit测试调试过后,需要在接口文档中详细的去编写给客户端开发同学看的一份文档,而且稍微不注意就有可能写错一个字母,下面来段单口相声(PS: 不会单口相声的程序员不是好产品!!!)
场景:APP活动接口
任务:我,APP开发者
时间:及其困乏的下午
我:Hi,哥们,接口开发好了,文档已经在git上面更新。
APP开发者:恩,我来请求一下。
......大约半分钟后...
APP开发者:接口请求不到。
我:(内心:怎么可能,我都单元测试过了,我确信我看的都是绿的啊,绿的啊,)你是不是写的有问题,自己检查一下哈(PS:怎么可能是我的问题)。
........大约一分钟后......
APP开发者:请求不到。
APP开发者:请求不到。
APP开发者: 请求不到。
我: 我来看一下(PS :我也是客户端开发者),没什么问题,怎么就请求不到呢,好吧我笑而不语的把/INfo 修改成/info SUCCESS !
也许上面的经历你也经历过,我也只是说明一下有这么中情况,事情是真实的,剧情嘛~ 每一个程序员都是一个优秀的导演,哈哈哈 ~ 下面切入整体,介绍一下怎么把Swagger2 和 SpringMVC 结合,看到最后的结果,你就知道Swagger2的有点了。

集成步骤
- 构建Maven工程
- 添加Swagger2依赖

* 配置Swagger2
@Component
@Configuration
@EnableSwagger2
@EnableWebMvc
@ComponentScan("com.zhaoshuai.controller")
public class Swagger2Config {
@Bean
public Docket createAPI() {
return new Docket(DocumentationType.SWAGGER_2).forCodeGeneration(true).select().apis(RequestHandlerSelectors.any())
//过滤生成链接
.paths(PathSelectors.any()).build().apiInfo(apiInfo());
}
private ApiInfo apiInfo() {
Contact contact=new Contact("赵帅","http://blog.maileba.top","zhaoshuaivov@163.com");
ApiInfo apiInfo = new ApiInfoBuilder().license("Apache License Version 2.0").title("Swagger 集成测试").description("Swagger API Teste").contact(contact).version("1.0").build();
return apiInfo;
}
}
* 设置spring-mvc.xml
<mvc:default-servlet-handler />
<mvc:resources location="classpath:/META-INF/resources/" mapping="swagger-ui.html"/>
<mvc:resources location="classpath:/META-INF/resources/webjars/" mapping="/webjars/**"/>
* 验证 http://ip:prot/project_name/swagger-ui.html 如果没有project_name 则省去
