本篇文章主要介绍了在idea环境下构建springCloud项目,小编觉得挺不错的,现在分享给大家,也给大家做个参考。一起跟随小编过来看看吧
 springCloud是基于springboot搭建的微服务。它利用Spring Boot的开发便利性巧妙地简化了分布式系统基础设施的开发,如服务发现注册、配置中心、消息总线、负载均衡、断路器、数据监控等,都可以用Spring Boot的开发风格做到一键启动和部署。
spring cloud官方文档:http://projects.spring.io/spring-cloud/ spring cloud 中文网 : https://springcloud.cc/ 最终搭建后的工程源代码:https://github.com/onpwerb/SpringCloud 一、新建maven工程 根据spring cloud官方文档,在pom.xml导入如下代码
<!-- spring cloud 配置 --> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.4.5.RELEASE</version> </parent> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Camden.SR6</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-config</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka</artifactId> </dependency>
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:
<!-- @EnableEurekaServer --> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-netflix-eureka-server</artifactId> <!--<version>1.1.6.RELEASE</version>--> </dependency> </dependencies>
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/service
http://localhost:8083/service2
http://localhost:8084/service/service
http://localhost:8084/service2/service2
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持脚本之家。
