When configuring Eureka, the status displays the computer name instead of localhost and IPADDR, which is the local IP

Status The computer name is displayed instead of localhost Configuration related

Status The display format can be changed , The default configuration is Computer name ： service name ： port 、ipAddr The default is 192.168.247.1 as follows ：

In fact, in the process of development , The default configuration is useless , Must be changed to localhost、 meanwhile ipAddr It should also be for localhost Otherwise, follow-up service method access .

For each service configuration ：

#  To configure eureka The status of 

eureka.instance.hostname=localhost
eureka.instance.instance-id=${
    eureka.instance.hostname}:${
    spring.application.name}:${
    server.port}

#  Use ip Address registration 
eureka.instance.prefer-ip-address=true

#  The name of the configuration service 
spring.application.name=order_service

Configuring the above information can make Status The display format of is localhost: Application name : port Show ：

take ipAddr Change it to localhost：

cmd go in dos Command input ipconfig：

The problem is usually caused by downloading VM ware And other similar software , There are many network cards .

Micro services to eureka When registering in the registry , According to the IP The address is abnormal. It's all localhost Or host name .（ Under normal circumstances , What should be displayed is the server where the microservice is located IP Address ）

Because the server is equipped with multiple network cards , Lead to eureka When discovering microservices , Unable to determine which network card the micro service is registered with , Therefore, the default display is localhost Or host name .

You need to ignore the impact of the network card on the registry in the configuration file ：

#  Microservice name 
spring.application.name=service-name

#  port 
server.port=8002

#  Consumer address 
eureka.instance.ip-address=localhost
 
# With IP Address the way to eureka To register , Domain name change ip
eureka.instance.prefer-ip-address=true
 
#Npcap Loopback Adapter： Is the name of the ignored network card 
spring.cloud.inetutils.ignored-interfaces[0]=Npcap Loopback Adapter
 

#  To configure Staus Display format 
eureka.instance.instance-id=${spring.cloud.client.address}:${spring.application.name}:${server.port}

#${spring.cloud.client.address}： For the server where the microservice is located IP Address 
#${spring.application.name}： The name of the micro service 
#${server.port}： Is the microservice port number 

The core is ：eureka.instance.ip-address=localhost Configure the ip Address . If this is not configured, it will default to the host ip.

When the configuration is complete ipAddr It becomes localhost. You can visit it normally .
