Question

我正在尝试使用带Grails的MySQL ..根据Grails的文档，我已经下载了MySQL连接器并将jar文件放在路径grails-app / lib。

但是在运行应用程序时，我遇到了很多错误。其中一些如下，我认为如果解决可以解决其余的问题。

| Configuring classpath.
| Environment set to development.....
| Packaging Grails application.....

请帮我解决这个问题...

Answer 1

文档在哪里说grails-app/lib？我认为它应该只是lib/
你确定你把二进制jar放在那里，而不是某种源代码jar吗？

您应该移除grails-app内所做的任何内容，然后只需取消注释该行：

    // runtime 'mysql:mysql-connector-java:5.1.16'

grails-app/conf/BuildConfig.groovy

Grails与MySQL抛出错误
