eureka学习(二)

eureka服务端创建好后，现在我们让eureka客户端(也就是服务提供者)注册到eureka上去。

首先加入依赖包：

<!--将微服务provider注册到eureka-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-config</artifactId>
        </dependency>

<!--保证info信息可以显示主管监控和信息配置-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<build>
  <finalName>microservicecloud</finalName>
  <resources>
    <resource>
      <directory>src/main/resources</directory>
      <filtering>true</filtering>
    </resource>
  </resources>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-resources-plugin</artifactId>
      <configuration>
        <delimiters>
          <delimit>$</delimit>
        </delimiters>
      </configuration>
    </plugin>
  </plugins>
</build>

yml文件里加入eureka服务端的地址：

spring:
  application:
    name: microservicecloud     #此为微服务的名称，注册到eureka时APPLICATIOIN处显示的就是这个，集群时此名称要一致
eureka:
  client:
    service-url:
      defaultZone: http://localhost:7001/eureka  
  instance:
    instance-id: microservicecloud           #些处注册到eureka上时，status处显示的名称，看下图中黑圈处
    prefer-ip-address: true       #此处为放在eureka中status上时显示ip

info:
  app.name: microservicecloud-test
  company.name: person
  build.artifactId: $project.artifactId$
  build.version: $project.version$

启动类里面加入@EnableEurekaClient

@SpringBootApplication
@EnableEurekaClient   //eureka客户端，启动后自动注册到服务端
public class ServerProvider {
    public static void main(String[] args) {
        SpringApplication.run(ServerProvider.class, args);
    }
}

上图中，我图黑圈那里，显示的为本地localhost,与上面对应。
