springcloud第二步：发布服务提供者

创建项目service-member

Maven依赖

<parent>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-parent</artifactId>

            <version>1.5.2.RELEASE</version>

            <relativePath /> <!-- lookup parent from repository -->

      </parent>

      <properties>

            <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

            <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

            <java.version>1.8</java.version>

      </properties>

      <dependencies>

            <dependency>

            </dependency>

      </dependencies>

      <dependencyManagement>

            <dependencies>

                       <groupId>org.springframework.cloud</groupId>

                       <artifactId>spring-cloud-dependencies</artifactId>

                       <type>pom</type>

                       <scope>import</scope>

                  </dependency>

            </dependencies>

      </dependencyManagement>

      <build>

            <plugins>

                  <plugin>

                       <groupId>org.springframework.boot</groupId>

                       <artifactId>spring-boot-maven-plugin</artifactId>

                  </plugin>

            </plugins>

      </build>

      <repositories>

            <repository>

                  <id>spring-milestones</id>

                  <name>Spring Milestones</name>

                  <url>https://repo.spring.io/milestone</url>

                  <snapshots>

                       <enabled>false</enabled>

                  </snapshots>

            </repository>

      </repositories>

application.yml配置

eureka:

  client:

    serviceUrl:

      defaultZone: http://localhost:8888/eureka/

server:

  port: 8762

spring:

  application:

    name: service-member

服务接口

@RestController

public class MemberController {

 

      @RequestMapping("/getUserList")

      public List<String> getUserList() {

            List<String> listUser = new ArrayList<String>();

            listUser.add("zhangsan");

            listUser.add("lisi");

            listUser.add("yushengjun");

            return listUser;

      }

 

}

 

发布服务

通过注解@EnableEurekaClient 表明自己是一个eurekaclient.

@SpringBootApplication

@EnableEurekaClient

public class AppMember {

 

      public static void main(String[] args) {

            SpringApplication.run(AppMember.class, args);

      }

 

}

演示效果

需要指明spring.application.name,这个很重要，这在以后的服务与服务之间相互调用一般都是根据这个name 。 
启动工程，打开127.0.0.1:8888 ，即eureka server 的网址：

 

你会发现一个服务已经注册在服务中了，服务名为SERVICE-HI ,端口为7862

这时打开 http://127.0.0.1:8762/getUserList ，你会在浏览器上看到 :

["zhangsan","lisi","yushengjun"]
