2019独角兽企业重金招聘Python工程师标准>>> 
一、新建maven工程
根据spring cloud官方文档，在pom.xml导入如下代码
org.springframework.boot spring-boot-starter-parent 1.4.5.RELEASE org.springframework.cloud spring-cloud-dependencies Camden.SR6 pom import org.springframework.cloud spring-cloud-starter-config org.springframework.cloud spring-cloud-starter-eureka
二、建立注册中心
新建名称为 discovery 的 module
1.在该module下的pom.xml导入如下配置：
org.springframework.cloud spring-cloud-netflix-eureka-server
2.在src/main/java目录下新建discovery文件夹，然后新建一个application
package discovery; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer; @SpringBootApplication @EnableEurekaServer public class DiscoveryApplicaion { public static void main(String[] args) { SpringApplication.run(DiscoveryApplicaion.class, args); } }
3.在该module下的src/main/resources文件夹下，新建文件application.yml，配置注册中心eureka的相关服务
server: port: 8081 eureka: instance: hostname: localhost client: registerWithEureka: false fetchRegistry: false serviceUrl: defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
三、构建一个服务A
新建一个名为service的module
1.在src/main/java目录下新建service文件夹，然后新建一个application
package service; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.client.discovery.EnableDiscoveryClient; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; @SpringBootApplication @EnableDiscoveryClient @RestController public class ServiceApplication { @GetMapping("/service") public String service(){ return "service"; } public static void main(String[] args) { SpringApplication.run(ServiceApplication.class, args); } }
2.在该module下的src/main/resources文件夹下，新建文件application.yml
spring: application: name: service.service eureka: client: serviceUrl: defaultZone: http://localhost:8081/eureka/ server: port: 8082
四、构建第二个服务B
新建一个名为service2的module
1.在src/main/java目录下新建service2文件夹，然后新建一个application
package service2; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.client.discovery.EnableDiscoveryClient; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @SpringBootApplication @EnableDiscoveryClient @RestController public class Service2Application { @RequestMapping("/service2") public String service2(){ return "service2"; } public static void main(String[] args) { SpringApplication.run(Service2Application.class, args); } }
2.在该module下的src/main/resources文件夹下，新建文件application.yml
spring: application: name: service2 eureka: client: serviceUrl: defaultZone: http://localhost:8081/eureka/ server: port: 8083
五、配置网关
新建名称为 gateway 的 module
1.在该module下的pom.xml导入如下配置：
package gateway; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.netflix.eureka.EnableEurekaClient; import org.springframework.cloud.netflix.zuul.EnableZuulProxy; @SpringBootApplication @EnableZuulProxy @EnableEurekaClient public class GatewayApplication { public static void main(String[] args) { SpringApplication.run(GatewayApplication.class, args); } }
2.在src/main/java目录下新建gateway文件夹，然后新建一个application
eureka: client: serviceUrl: defaultZone: http://localhost:8081/eureka/ spring: application: name: gateway server: port: 8084 zuul: routes: service: /service/** service2: /service2/**
3.在该module下的src/main/resources文件夹下，新建文件application.yml
六、启动服务
先启动discovery模块，再启动其他模块
在浏览器依次输入：
http://localhost:8081/
http://localhost:8082/servicehttp://localhost:8083/service2http://localhost:8084/service/servicehttp://localhost:8084/service2/service2
