Spring Cloud Zuul 集成Swagger

1.准备服务注册中心eureka-server

2.创建微服务swagger-service-a

step1. 创建微服务swagger-service-a(Spring Boot项目)，添加eureka-client起步依赖，web起步依赖 和swagger依赖

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> </dependency> <!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger2 --> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>2.9.2</version> </dependency> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> <version>2.9.2</version> </dependency>

step2.在配置类添加注解@EnableDiscoveryClient ，，将当前应用 添加到 服务治理体系中，开启微服务注册与发现。

step3.配置swagger

package com.example.swaggerservicea;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import springfox.documentation.builders.ApiInfoBuilder;import springfox.documentation.builders.PathSelectors;import springfox.documentation.builders.RequestHandlerSelectors;import springfox.documentation.service.ApiInfo;import springfox.documentation.spi.DocumentationType;import springfox.documentation.spring.web.plugins.Docket;import springfox.documentation.swagger2.annotations.EnableSwagger2;@Configuration@EnableSwagger2public class SwaggerConfig { @Bean public Docket api() { return new Docket(DocumentationType.SWAGGER_2) .apiInfo(apiInfo()) .select() .apis(RequestHandlerSelectors.any()) .paths(PathSelectors.any()).build(); } private ApiInfo apiInfo() { return new ApiInfoBuilder() .title("swagger-service-a 实例文档") .description("swagger-service-a 实例文档 1.0") .termsOfServiceUrl("https:github") .version("1.0") .build(); }}

step4.application.properties文件中添加配置

#微服务基本信息
spring.application.name=swagger-service-a
server.port=10010
#注册中心
eureka.client.serviceUrl.defaultZone=http://localhost:1001/eureka/
#要生成文档的package
swagger.base-package=com.example

step5.添加一个微服务提供的功能

import org.springframework.beans.factory.annotation.Autowired;import org.springframework.cloud.client.discovery.DiscoveryClient;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RestController;@RestControllerpublic class AaaController { @Autowired DiscoveryClient discoveryClient; @GetMapping("/service-a") public String dc() { String services = "service-a Services: " + discoveryClient.getServices(); System.out.println(services); return services; }}

step6.启动微服务，访问 http://localhost:10010/swagger-ui.html

3.创建微服务swagger-service-b （参考swagger-service-a ）， 启动微服务swagger-service-b并访问http://localhost:10020/swagger-ui.html

4.构建API网关并整合Swagger

step1.创建API网关微服务swagger-api-gateway，添加eureka-client起步依赖，zuul起步依赖 和 swagger依赖 :spring-cloud-starter-netflix-eureka-client，spring-cloud-starter-netflix-zuul

<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-zuul</artifactId> </dependency> <!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger2 --> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>2.9.2</version> </dependency> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> <version>2.9.2</version> </dependency>

step2.在配置类添加注解@SpringCloudApplication ，@EnableZuulProxy

step3.配置swagger

import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import springfox.documentation.builders.ApiInfoBuilder;import springfox.documentation.builders.PathSelectors;import springfox.documentation.builders.RequestHandlerSelectors;import springfox.documentation.service.ApiInfo;import springfox.documentation.spi.DocumentationType;import springfox.documentation.spring.web.plugins.Docket;import springfox.documentation.swagger2.annotations.EnableSwagger2;@Configuration@EnableSwagger2public class SwaggerConfig { @Bean public Docket api() { return new Docket(DocumentationType.SWAGGER_2) .apiInfo(apiInfo()) .select() .apis(RequestHandlerSelectors.any()) .paths(PathSelectors.any()).build(); } private ApiInfo apiInfo() { return new ApiInfoBuilder() .title("swagger-service 实例文档") .description("swagger-service 实例文档 1.0") .termsOfServiceUrl("https:github") .version("1.0") .build(); }}

step4.配置swagger

package com.example.swaggerapigateway;import java.util.ArrayList;import java.util.List;import org.springframework.context.annotation.Primary;import org.springframework.stereotype.Component;import springfox.documentation.swagger.web.SwaggerResource;import springfox.documentation.swagger.web.SwaggerResourcesProvider;@Component@Primaryclass DocumentationConfig implements SwaggerResourcesProvider { @Override public List<SwaggerResource> get() { List resources = new ArrayList<>(); resources.add(swaggerResource("service-a", "/swagger-service-a/v2/api-docs", "2.0")); resources.add(swaggerResource("service-b", "/swagger-service-b/v2/api-docs", "2.0")); return resources; } private SwaggerResource swaggerResource(String name, String location, String version) { SwaggerResource swaggerResource = new SwaggerResource(); swaggerResource.setName(name); swaggerResource.setLocation(location); swaggerResource.setSwaggerVersion(version); return swaggerResource; }}

step5.application.properties文件中添加配置

#微服务基本信息
spring.application.name=swagger-api-gateway
server.port=10030
#注册中心
eureka.client.serviceUrl.defaultZone=http://localhost:1001/eureka/
#要生成文档的package
swagger.base-package=com.example

step6.启动微服务，访问http://localhost:10030/swagger-ui.html
