Eureka服务提供端搭建

1.pom.xml依赖添加

   <!-- Spring Boot -->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.6.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <modelVersion>4.0.0</modelVersion>

    <artifactId>eureka-client</artifactId>

    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>

    <!-- Spring Cloud -->
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Finchley.SR2</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

    

2.配置文件

spring:
  application:
    name: eureka-client-user-service

server:
  port: 8081

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/
  instance:
    preferIpAddress: true #采用IP注册
    instance-id: ${spring.application.name}:${spring.cloud.client.ip-address}:${server.port} #定义实例ID格式

3.创建启动类

@SpringBootApplication
@EnableDiscoveryClient
public class MyApplication {

    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }

}

4.服务提供类

@RestController
@RequestMapping("/user")
public class UserController {

    @GetMapping("/hello")
    public String hello(){
        return "hello , I'm eureka client!";
    }
}
