Question

我正在创建一个具有Web，MySQL和JPA依赖关系的基本spring应用程序。我在服务器上设置了一个嵌入式数据库，并试图在我的spring应用程序中访问它。我已经在properties和application.yml文件中输入了所有正确的详细信息，但仍然收到错误消息。我收到的确切错误是：

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no 
embedded datasource could be configured.

Reason: Failed to determine a suitable driver class"

任何帮助将不胜感激。

application-dev.yml

spring:

  profiles: dev

  thymeleaf:
    # do not cache -> hot reload of templates
    cache: false

  datasource:
    driverClassName: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/bookerdb
    username: booker
    password: ${db_password}
  jpa:
    hibernate:
      connection:
        charset: utf8
        useUnicode: true
      ddl-auto: update
    naming-strategy: org.hibernate.cfg.ImprovedNamingStrategy
    properties.hibernate.dialect: org.hibernate.dialect.PostgreSQL94Dialect

application.properties ：（密码已编辑）

initial_admin_password=test
db_password=test
profile=dev
