Springcloud基于Zuul做网关路由聚合SwaggerUi的配置

第一步，在服务中手动创建Docket；
 

swagger配置类SwaggerConfig

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo());
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("公共APi")
                .description("测试")
                .version("1.0")
                .build();
    }
}

第二步，引入依赖
 

      <dependency>
            <groupId>com.spring4all</groupId>
            <artifactId>swagger-spring-boot-starter</artifactId>
            <version>1.8.0.RELEASE</version>
        </dependency>

第三步，在启动类上加入注解@EnableSwagger2Doc

 

@SpringCloudApplication
@EnableSwagger2Doc
public class PublicApplication {

    @Bean
    public RestTemplate restTemplate(RestTemplateBuilder builder) {
        return builder.build();
    }

    public static void main(String[] args) {
        SpringApplication.run(PublicApplication.class, args);
    }

第三步在网关Zuul启动类上加上EnableSwagger2Doc，并配置SwaggerUi Resource

@EnableZuulProxy
@EnableFeignClients
@SpringCloudApplication
@EnableCaching
@EnableSwagger2Doc
public class TripGatewayApplication {
    public static void main(String[] args) {
        SpringApplication.run(TripGatewayApplication.class, args);
    }

    @Primary
    @Component
    class DocumentationConfig implements SwaggerResourcesProvider {


        @Override
        public List<SwaggerResource> get() {
            List<SwaggerResource> swaggerResourceList = new ArrayList<>();
            swaggerResourceList.add(createSwaggerResource("public-swagger", "http://localhost:10015/v2/api-docs", "1.0"));
            swaggerResourceList.add(createSwaggerResource("country-swagger", "http://localhost:10012/v2/api-docs", "1.0"));
            return swaggerResourceList;
        }

        private SwaggerResource createSwaggerResource(String name, String url, String version){
            SwaggerResource swaggerResource = new SwaggerResource();
            swaggerResource.setName(name);
            swaggerResource.setUrl(url);
            swaggerResource.setSwaggerVersion(version);
            return swaggerResource;
        }
    }

}

第五步，分别在上public-swagger、country-swagger 两个服务中加入跨域请求的配置；

@Configuration
public class CorsConfig {
    private CorsConfiguration buildConfig() {
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.addAllowedOrigin("*");
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addAllowedMethod("*");
        return corsConfiguration;
    }

    @Bean
    public CorsFilter corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        // 配置所有请求
        source.registerCorsConfiguration("/**", buildConfig());
        return new CorsFilter(source);
    }

}

大功告成，看效果；说明：网关端口是10001，public-swagger端口是10015、country-swagger端口是10012
