Spring Cloud Zuul集成Swagger實(shí)現(xiàn)過(guò)程解析
Spring Cloud Zuul 集成Swagger
1.準(zhǔn)備服務(wù)注冊(cè)中心eureka-server
2.創(chuàng)建微服務(wù)swagger-service-a
step1. 創(chuàng)建微服務(wù)swagger-service-a(Spring Boot項(xiàng)目),添加eureka-client起步依賴,web起步依賴 和swagger依賴
<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.在配置類添加注解@EnableDiscoveryClient ,,將當(dāng)前應(yīng)用 添加到 服務(wù)治理體系中,開(kāi)啟微服務(wù)注冊(cè)與發(fā)現(xiàn)。
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
@EnableSwagger2
public 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 實(shí)例文檔")
.description("swagger-service-a 實(shí)例文檔 1.0")
.termsOfServiceUrl("https:github")
.version("1.0")
.build();
}
}
step4.application.properties文件中添加配置
#微服務(wù)基本信息
spring.application.name=swagger-service-a
server.port=10010
#注冊(cè)中心
eureka.client.serviceUrl.defaultZone=http://localhost:1001/eureka/
#要生成文檔的package
swagger.base-package=com.example
step5.添加一個(gè)微服務(wù)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;
@RestController
public 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.啟動(dòng)微服務(wù),訪問(wèn) http://localhost:10010/swagger-ui.html
3.創(chuàng)建微服務(wù)swagger-service-b (參考swagger-service-a ), 啟動(dòng)微服務(wù)swagger-service-b并訪問(wèn)http://localhost:10020/swagger-ui.html
4.構(gòu)建API網(wǎng)關(guān)并整合Swagger
step1.創(chuàng)建API網(wǎng)關(guān)微服務(wù)swagger-api-gateway,添加eureka-client起步依賴,zuul起步依賴 和 swagger依賴 :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.在配置類添加注解@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
@EnableSwagger2
public 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 實(shí)例文檔")
.description("swagger-service 實(shí)例文檔 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
@Primary
class 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
#微服務(wù)基本信息
spring.application.name=swagger-api-gateway
server.port=10030
#注冊(cè)中心
eureka.client.serviceUrl.defaultZone=http://localhost:1001/eureka/
#要生成文檔的package
swagger.base-package=com.example
step6.啟動(dòng)微服務(wù),訪問(wèn)http://localhost:10030/swagger-ui.html
