# 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。

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

         <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.5.0</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.5.0</version>
        </dependency>

        <!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-core -->
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-core</artifactId>
            <version>2.8.6</version>
        </dependency>

        <!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind -->
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>2.8.6</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-annotations -->
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-annotations</artifactId>
            <version>2.8.6</version>
        </dependency>

* 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
