如何在Grails 3中设置数据库？手册看起来已经过时了:http://grails.github.io/grails-doc/3.0.x/guide/single.html#dataSource
因为它提供了使用grove代码进行设置的示例，如下所示:
dataSource {
pooled = true
dbCreate = "update"
url = "jdbc:mysql://localhost:3306/my_database"
driverClassName = "com.mysql.jdbc.Driver"
dialect = org.hibernate.dialect.MySQL5InnoDBDialect
username = "username"
password = "password"
...
当我有
application.yml与dataSource:
pooled: true
jmxExport: true
driverClassName: org.h2.Driver
username: sa
password:
最新的方法是什么？
最佳答案
这是当前有多个数据源的postgres示例。我发现冗余是必要的，因为grails，spring和hibernate期望看到配置信息的级别存在一些差异。这使所有人都满意。还包括jdbc驱动程序的运行时依赖项。对于postgres，它是
dependencies {
// all other dependencies
runtime "org.postgresql:postgresql:9.4.1208"
}
[application.yml文件的开始。是的，“-”行必须存在。他们可以防止configslurper变得混乱。]
