博客内容讲述了在Spring Boot应用启动时遇到`ConverterNotFoundException`的问题，具体表现为无法将`String`类型转换为`java.sql.Driver`。错误源于`application.yml`配置文件中'driver'属性的误配置。解决方案是将配置文件中的'driver'改为'driver-class-name'，并清理缓存后再进行编译。

APPLICATION FAILED TO START

Description:

Failed to bind properties under 'spring.datasource.druid.driver' to java.sql.Driver:

Property: spring.datasource.druid.driver
Value: com.mysql.cj.jdbc.Driver
Origin: class path resource [application.yml]:11:15
Reason: No converter found capable of converting from type [java.lang.String] to type [java.sql.Driver]

Action:

Update your application's configuration

Disconnected from the target VM, address: '127.0.0.1:51259', transport: 'socket'

=================================================================

1.错误的 application.yml 配置

大部分电脑都不需要这样配置，

配置中的属性都是颜色都是深色，没有变，是因为 driver: com.mysql.cj.jdbc.Driver

将 driver 改为 driver-class-name 即可！
