问题描述
您好亲爱的程序员，
我正在学习如何使用电子书Grails - 快速入门指南与Groovy / Grails合作，现在我正在那里工作示例项目称为TekDays。这个项目的每一步都有记录，并且描述得很好，但是我找不到我犯的一个错误。
我使用Grovvy / Grails工具套件（GGTS）作为IDE。
- Grails版本：2.2.4
- Groovy / Grails工具套件版本：3.4.0。 RELEASE
一切正常，但是因为我将数据库连接添加到我的MySQL数据库中，所以出现此错误：
|加载Grails 2.2.4
|配置类路径。
|环境设置为开发.....
|打包Grails应用程序.....
|运行Grails应用程序

$ b如果需要更多信息，我会尽快将其添加如果可以的话。
非常感谢您提供的每一个有用答案或评论！ Lukas，你需要在你的/ lib文件夹中添加jdbc-driver并在你的BuldConfig.groovy中添加正确的依赖项，例如：
runtime'mysql：mysql-connector-java：5.1.22'
当然取决于您使用的版本。
回到当天，我也做了这个例子我知道他们提到了这一点。
给它一下！
Hello Dear Programmers,
I'm learning to work with Groovy / Grails with the eBook "Grails - A Quick Start Guide" and now im working there with an example project called TekDays. Every step for this project is documented and well described but i cant find an fault i made..I'm using the Grovvy / Grails Tool Suite (GGTS) as IDE.
- Grails Version: 2.2.4
- Groovy/Grails Tool Suite Version: 3.4.0.RELEASE
Everything worked fine but since I added the database connection to my MySQL database I'm getting this error:

}
If more information is needed, I will add it as fast as i can.
Thank you very much for every helpful answer or comment!
解决方案 Lukas, you need to add the jdbc-driver in you /lib-folder and add the correct dependency in your BuldConfig.groovy, for example:
runtime 'mysql:mysql-connector-java:5.1.22'
Of course depending on the version that you're using.
Back in the day I also did this example and I know that they mention this.
Give it a go!
