1、POM配置
和普通Spring Boot工程相比,仅仅添加了Eureka、Spring Boot Starter Actuator依赖和Spring Cloud依赖管理
<dependencies> <!--添加Eureka Server依赖--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka</artifactId> </dependency> <!--服务健康检测,务必添加,不然负载均衡消费此服务时,断路器会打开--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> </dependencies> <dependencyManagement> <dependencies> <!--Spring Cloud依赖版本管理--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Dalston.SR1</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement>
02、使能Eureka Client
@SpringBootApplication
@EnableEurekaClient//使能Eureka Server服务
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
03、src/main/resources工程配置文件application.yml
server:
port: 2001 #默认启动端口
spring:
application:
name: hello-service-provider #应用名
eureka: instance: hostname: hello-service-provider #主机名
client:
serviceUrl:
defaultZone: http://localhost:1000/eureka/ #服务注册中心地址。若部署在其它IP主机,请将localhost改为主机IP
04、提供服务
@RestController public class HelloController { @GetMapping("/hello") public String hello() { System.out.println("Time" + System.currentTimeMillis()); return "Hello Spring Cloud"; } }
服务消费者通过http://hello-service-provider/hello即可消费此服务。
