Question

我尝试将grails-3.0.8版本连接到mysql作为我的数据库。在此版本中，BuildConfig.groovy已被application.yml取代。但是，在使用mysql配置后，我无法使用命令行启动grails服务器。我的配置有什么问题？请帮忙。这是我第一次使用grails。这是application.yml代码

更改

下方的网址

url: jdbc:mysql://localhost/grails_db;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE

到

url: jdbc:mysql://localhost/grails_db

并将以下代码添加到 build.gradle 文件

runtime 'mysql:mysql-connector-java:5.1.29'

无法在Grails-3.0.8中使用mysql配置启动服务器
