这里基于微服务’ralab-nlp’和’ralab-client’
- Add the Maven spring-cloud-starter-netflix-eureka-client denpendency
- Add @EnableEurekaClient to the application class
- Add spring.application.name parameter to the application.properties file
这时修改服务提供者ralab-nlp的pom.xml文件，引入eureka-client依赖

public class RalabNlpApplication {
public static void main(String[] args) {
SpringApplication.run(RalabNlpApplication.class, args);
}
}
修改application.properties文件
spring.application.name=nlp-service
server.port=8090
运行RalabNlpApplication
同时修改服务消费者ralab-client的pom.xml文件，引入eureka-client依赖1

修改application.properties文件
spring.application.name=nlp-client

运行RalabClientApplication
这时在浏览器打开http://localhost:8761/
可以看到注册实例nlp-service和nlp-client
