【问题描述】:
我正在 IntelliJ IDEA Community IDE 中编写一个 Java 项目。本项目的技术栈:
- 弹簧靴;
- Spring 数据 JPA;
- MySQL。
我在项目中有application.yml 文件来连接数据库,但是当我运行我的应用程序时,出现错误:
APPLICATION FAILED TO START
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
我不知道为什么我的项目看不到我的 application.yml 文件,该文件位于项目中的 /src/main/resources/database 路径中。
有什么想法吗?
application.yml:
spring:
jpa:
database: mysql
show-sql: true
hibernate:
ddl-auto: update
datasource:
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://localhost:3306/map
username: root
password: abcd

【问题讨论】:
-
它应该直接在资源目录中。
-
application.yml必须在src/main/resources而不是子目录中。 -
