我试图获取某些DataSource.groovy变量并将它们放入外部属性文件中。
Config.groovy中
grails.config.locations = [
"file:./marcus-sercret.properties"
]
DataSource.groovy中
dataSource {
logSql = true
pooled = true
dbCreate = "validate"
driverClassName = "com.mysql.jdbc.Driver"
dialect = org.hibernate.dialect.MySQL5InnoDBDialect
url = ""
username = "myusername"
password = ""
...
<stuff delete>
}
marcus-secret.properties
println '************************************ MARCUS SECRET'
dataSource.url = "jdbc:mysql://localhost:3351/chrome_expense"
mikev="xxxxxxxxx"
当我启动我的应用程序时，我得到以下例外。当我将url放入DataSource文件（没有属性文件）时，它工作正常。我知道属性文件正在加载，因为mikev已填充。
感谢您的帮助...... - 迈克

属性文件仅包含键和值。如果要使用某些自定义配置，请使用Groovy文件。
<强>马库斯-secret.groovy
println "Using external configuration..." //works on groovy files
dataSource.url = "jdbc:mysql://localhost:3351/chrome_expense"
