My service "app-name" shuts down unexpectedly right after having started. At that time
- The eureka server is running on port 8761
- The service has been successfully discovered by the eureka server (registration status:
204,registering application with eureka with status UP) - The discovered app has fully started on port 9100 (
Started <app-name> in 7.427 seconds (JVM running for 7.999)
If I don't include service discovery the app starts up fine
Here is the java implementation
//Eureka server
@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaServerApplication.class, args);
}
}
//Discovered service
@SpringBootApplication
@EnableDiscoveryClient
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
The application.properties (or bootstrap.properties)
# properties for discovered service
spring.application.name=<app-name>
spring.profiles.active=default
spring.cloud.config.uri=http://localhost:8888
server.port=9100
eureka.client.service-url.default-zone=http://localhost:8761/eureka
# properties for eureka
spring.application.name=symphony-nlp-eureka-server
server.port=8761
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
Here are the logs

Thanks for the help
回答1:
I have the same configuration as yours, I also get discovery client shutdown issue. Adding
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
in pom.xml fixed my issue.
Hope it works for you too. But I am still trying to figure out why, as I follow the spring cloud course to build the application, the course author don't add 'spring-boot-starter-web' specifically.
