Swagger实现接口版本号管理

前言：使用swagger暴露对外接口时原则是每个系统在不同的迭代版本仅仅需要暴露该迭代版本的接口给外部使用，客户端不需要关心不相关的接口

---

先来看张效果图

 下面是实现代码：

定义注解ApiVersion：

/**
 * 接口版本管理注解
 * @author 周宁
 * @Date 2018-08-30 11:48
 */
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface ApiVersion {

    /**
     * 接口版本号(对应swagger中的group)
     * @return String[]
     */
    String[] group();

}

 

定义一个用于版本常量的类ApiVersionConstant

/**
 * api版本号常量类
 * @author 周宁
 * @Date 2018-08-30 13:30
 */
public interface ApiVersionConstant {
    /**
     * 图审系统手机app1.0.0版本
     */
    String FAP_APP100 = "app1.0.0";

}

 

 更改SwaggerConfig添加Docket(可以理解成一组swagger 接口的集合)，并定义groupName,根据ApiVersion的group方法区分不同组(迭代)的接口，代码如下:

@Configuration
@EnableSwagger2
@EnableWebMvc
public class SwaggerConfig {
    
    //默认版本的接口api-docs分组
    @Bean
    public Docket vDefault(){
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(buildApiInf())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.gysoft"))//controller路径
                .paths(PathSelectors.any())
                .build();
    }
    //app1.0.0版本对外接口
    @Bean
    public Docket vApp100(){
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(buildApiInf())
                .groupName(FAP_APP100)
                .select()
                .apis(input -> {
                    ApiVersion apiVersion = input.getHandlerMethod().getMethodAnnotation(ApiVersion.class);
                    if(apiVersion!=null&&Arrays.asList(apiVersion.group()).contains(FAP_APP100)){
                        return true;
                    }
                    return false;
                })//controller路径
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo buildApiInf(){
        return new ApiInfoBuilder()
                .title("接口列表")
                .termsOfServiceUrl("http://127.0.0.1:8080/swagger-ui.html")
                .description("springmvc swagger 接口测试")
                .version("1.0.0")
                .build();
    }

}
