我正在尝试将微服务与Eureka连接。
我已经在主类中添加了注释@EnableDiscoveryClient：
@EnableDiscoveryClient
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
我正在build.gradle中使用下一个依赖项：
compile group: 'org.springframework.cloud', name: 'spring-cloud-netflix-eureka-client', version: '2.0.1.RELEASE'
最后，我已将配置添加到application.yml
eureka:
client:
serviceUrl:
defaultZone: http://localhost:8761/eureka/
spring:
application.name: receipt-processing-microservice
而且，正如您可以建议的那样，它不起作用。在日志中，我看不到任何带有标签DiscoveryChannel或Eureka

也许您缺少配置的一部分？
我满足以下条件，并且一切运行正常：
#Eureka configuration
eureka.client.enabled=true
eureka.client.serviceUrl.defaultZone=${EUREKA_SERVICE_URL:http://admin:admin@localhost:7995}/eureka/
eureka.client.healthcheck.enabled=true
eureka.client.registerWithEureka=true
eureka.client.fetchRegistry=true
eureka.instance.leaseRenewalIntervalInSeconds=15
eureka.instance.leaseExpirationDurationInSeconds=30
您可以尝试使用更多参数，看看会发生什么。
此外，如果只是控制台日志问题，请检查eureka Web-ui中的服务列表：请参阅localhost：8761 /＃。

尝试启用调试日志。您将获得大量信息（可以将其重定向到文件），并尝试查看其下发生了什么—特别是在容器启动后以及发现客户端初始化时。在我的情况下，发现服务器正在8061端口上运行，我的服务注册日志如下所示（请参阅指示服务向eureka服务器发送请求注册的日志）
