swagger2的分组配置

当微服务的服务越来越多swagger2展示的越来越长这时候需要进行分页展示
swagger2头上有下拉框可以groupName进行分组展示

java代码代码：

@Configuration
@EnableSwagger2
public class SwaggerConfig {

@Bean
    public Docket createRestApi() {


        return new Docket(DocumentationType.SWAGGER_2)
        .globalOperationParameters(operationParameters())
        .groupName("第一个接口服务页面")
        .genericModelSubstitutes(DeferredResult.class)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.tan.oauth2.controller"))
                .paths(PathSelectors.any())
                .build();
    }
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title(" createRestApi  Spring Boot中使用Swagger2构建RESTful APIs")
                .description("更多Spring Boot相关文章请关注：http://blog.didispace.com/")
                .termsOfServiceUrl("http://github.com/")
                .contact("程序猿痛苦")
                .version("1.0")
                .build();
    }
    @Bean
    public Docket openRestApi() {
    Predicate<RequestHandler> predicate = new Predicate<RequestHandler>() {
            @Override
            public boolean apply(RequestHandler input) {
//                 Class<?> declaringClass = input.declaringClass();
//                 if (declaringClass == BasicErrorController.class)// 排除
//                     return false;
//                 if(declaringClass.isAnnotationPresent(ApiOperation.class)) // 被注解的类
//                     return true;
//                 if(input.isAnnotatedWith(ResponseBody.class)) // 被注解的方法
//                     return true;
//                 if (input.isAnnotatedWith(ApiOperation.class))//只有添加了ApiOperation注解的method才在API中显示
//                     return true;
                if (input.isAnnotatedWith(ApiOperation.class))//只有添加了ApiOperation注解的method才在API中显示
                return true;
                return false;
            }
        };
    return new Docket(DocumentationType.SWAGGER_2)
    .groupName("第二个接口服务页面")
    .genericModelSubstitutes(DeferredResult.class)
    .apiInfo(openapiInfo())
    .select()
    .apis(RequestHandlerSelectors.basePackage("com.tan.oauth2.controller2"))
//     .apis(predicate)
    .paths(PathSelectors.any())
    .build();
    }
    private ApiInfo openapiInfo() {
    return new ApiInfoBuilder()
    .title("openRestApi Spring Boot中使用Swagger2构建RESTful APIs")
    .description("更多Spring Boot相关文章请关注：http://blog.didispace.com/")
    .termsOfServiceUrl("http://github.com/")
    .contact("程序猿痛苦")
    .version("1.0")
    .build();
    }
   
    public  List<Parameter> operationParameters() {
    //添加head参数start
    ParameterBuilder tokenPar = new ParameterBuilder();
    List<Parameter> pars = new ArrayList<Parameter>();
    tokenPar.name("x-access-token")
    .description("令牌")
    .modelRef(new ModelRef("string"))
    .parameterType("header")
    .required(false)
    .build();
    pars.add(tokenPar.build());
    //添加head参数end
    return pars; 
    }
   
}
