intellij-idea - 无法在 Grails 3 中创建初始连接池

Question

我有一个带有 Intellij IDEA 2017.1.1 的 grails 3.2.7 应用程序。但问题是我无法为我的 MySql 数据库(开发环境)创建连接池。

Here is my application.yml

我是 grails 3 的新手，有人可以帮我解决这个问题吗？

Answer 1

您的构建文件似乎缺少这些依赖项

runtime "org.apache.tomcat:tomcat-jdbc:8.5.0"
runtime "org.apache.tomcat.embed:tomcat-embed-logging-log4j:8.5.0"

尝试添加它们，看看是否有效。
