我的服务“应用程序名称”在启动后立即意外关闭。
当时
- eureka服务器运行在8761端口
- 服务已成功被eureka服务器发现（注册状态：
204, registering application with eureka with status UP)
- 发现的应用程序已在端口 9100 上完全启动（
Started <app-name> in 7.427 seconds (JVM running for 7.999)
如果我不包括服务发现，应用程序启动正常
这是java实现
//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
这是日志
