spring-boot - Spring Cloud 配置不应用全局配置

Question

我在 spring cloud 配置 2020.0.3、spring boot 2.4.5 上遇到问题，详情：

• Yaml 配置文件在Multi-profile YAML 文档之后
• 我在配置服务器上有一个配置 yaml 文件。

my_cofig.yaml

spring:
  datasource:
    url: "jdbc:mariadb://localhost:3306/default_db"
    driver-class-name: org.mariadb.jdbc.Driver
    username: my_db
    password: 12345
---
spring:
  profiles: dev
  datasource:
    url: "jdbc:mariadb://localhost:3306/dev_db"

• 我已经通过浏览器从配置服务器加载了配置，这是正确的。但：
• 当我使用特定配置（例如 dev）运行 Spring 应用程序时，Spring 应用程序不能应用配置服务器上配置文件中定义的全局配置变量。它只加载 dev 的配置变量。

引导程序.yaml

server:
  port: 8081
spring:
  application:
    name: auth-service
  cloud:
    config:
      enabled: true
      fail-fast: true
      allow-override: true
      profile: dev
      uri: http://localhost:5000

错误详情：

Caused by: org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set

请帮助我，非常感谢！

spring:
  profiles:

This does not exist (it was deprecated if I am not mistaken). Please check the reference documentation.

I believe that what you are looking for is the following (reference documentation):

spring:
  datasource:
    url: "jdbc:mariadb://localhost:3306/default_db"
    driver-class-name: org.mariadb.jdbc.Driver
    username: my_db
    password: 12345
---
spring:
  config:
    activate:
      on-profile: dev
  datasource:
    url: "jdbc:mariadb://localhost:3306/dev_db"
