LOCAL_SNAPSHOT_PATH:C:\Users\Administrator\nacos\config does not exist ！！！

HuangDayu commented 4 years ago

I have configured a remote nacos server , Why go to get the local configuration file ? The application environment should not require nacos server .

I did not configure this address http://localhost:8848 , but nacos client has been constantly requesting this address.

cloud:
    nacos:
      config:
        enabled: false

When I turn off the config function, the first thing after the application starts is to request the address :http://localhost:8848.

KomachiSion commented 4 years ago

In our environment, it didn't happen. My suggestion is check configuration. Or have a debug and find out why the configuration is not available.

HuangDayu commented 4 years ago

Found the reason.

When I add different configuration files for different environments, for example:

  1. application-dev.yaml
  2. application-test.yaml
  3. application-prod.yaml

Then configure the profiles in bootstrap.yaml, for example:

spring:
  main:
    allow-bean-definition-overriding: true
  profiles:
    active: dev

The configuration of nacos config is in application-dev.yaml, then the configuration of nacos config does not take effect.

HuangDayu commented 4 years ago

When reading the configuration, does not support reading the corresponding configuration file according to spring.profiles.active ?

HuangDayu commented 4 years ago

bootstrap.yaml

spring:
  main:
    allow-bean-definition-overriding: true
  profiles:
    active: dev
  application:
    name: service-***
  cloud:
    config:
      enabled: false
      discovery:
        enabled: false
        service-id: cloud-config
      profile: dev,test,prod
    nacos:
      config:
        enabled: false

application-dev.yaml

spring:
  cloud:
    nacos:
      config:
        enabled: true
        server-addr: test.***.com:8848
        group: springcloud
      discovery:
        enabled: true
        server-addr: test.***.com:8848

          instance-id: ${spring.application.name}-${spring.cloud.client.ip-address}:${server.port}

When I turn off nacos config in bootstrap.yaml and open nacos config in application-dev.yaml, after the application starts, I don’t get the local configuration file like the previous one, but after the application is started, it will still get the remote configuration file for test.***.com:8848.

Is there a relationship between bootstrap.yaml and application-dev.yaml reading two configuration files ?

HuangDayu commented 4 years ago

I see, thanks.

application.yml与bootstrap.yml的区别
