ideal一直报这个错误

可是数据库配置弄好了
报错显示如下
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

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

Action:

Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

Process finished with exit code 0

无法配置DataSource：未指定’url’属性，也无法配置嵌入数据源

可能是.properties文件中datasource的配置出现错误，例如：地址值，数据库驱动，用户名，密码。

驱动不对吧

建议你把配置文件截图发出来，上面的聊天记录里的配置我初略看了下，是错的，正确的应该是下面这样

spring:
  datasource:
    url: jdbc:mysql://localhost/db_spring_security?useSSL=false&charracterEncoding=utf-8&useUnicode=true&serverTimezone=GMT%2b8
    username: root
    password: 123456
    driver-class-name: com.mysql.jdbc.Driver

DataSource里面没有设置url参数，检查有没有写错。
