    eureka.client.registerWithEureka=true
    eureka.client.fetchRegistry=true

This is application.properties file content:

    # serivce name
    spring.application.name=student-service
    # port
    server.port=6161
    # eureka server url
    eureka.client.service-url.defaultZone=http://localhost:6969/eureka
    eureka.client.registerWithEureka=true
    eureka.client.fetchRegistry=true

it is showing

com.sun.jersey.api.client.ClientHandlerException: org.apache.http.conn.ConnectTimeoutException: Connect to localhost:8761
Solution

  • Change configuration for the Eureka registry server eureka.client.serviceUrl.defaultZone like following (YAML syntax):

    eureka:
    client:
        #registerWithEureka: false
        #fetchRegistry: false
        serviceUrl:
            defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
