postgresql - 将 Postgres 与 Grails 结合使用

Question

有人让 Grails 与 Postgres 一起工作吗？我用过这个tutorial一切似乎都对我有意义并且是正确的。但是，当我“grails run-app”时出现此错误

Cannot create JDBC driver of class 'org.postgresql.Driver' for connect URL 'jdbc:postgres://10.0.0.21/tribes'
java.sql.SQLException: No suitable driver

我的数据源文件是

dataSource {
    pooled = true
    driverClassName = "org.postgresql.Driver"
    dialect = org.hibernate.dialect.PostgreSQLDialect
}
hibernate {
    cache.use_second_level_cache=true
    cache.use_query_cache=true
    cache.provider_class='com.opensymphony.oscache.hibernate.OSCacheProvider'
}
// environment specific settings
environments {
    development {
        dataSource {
            dbCreate = "update"
            url = "jdbc:postgres://10.0.0.21:5432/tribes"
            username = "grails"
            password = "grails"
        }   
    }   
    test {
        dataSource {
            dbCreate = "update"
            url = "jdbc:postgres://10.0.0.21:5432/tribes"
            username = "grails"
            password = "grails"
        }   
    }   
    production {
        dataSource {
            dbCreate = "update"
            url = "jdbc:postgres://10.0.0.21:5432/tribes"
            username = "grails"
            password = "grails"
        }   
    }   
}

来自FAQ :“[如果]你收到一个运行时错误，提示‘找不到合适的驱动程序’，很可能是传递给 DriverManager.getConnection 的 URL 格式不正确或不正确”。那你的怎么了？那么，本教程中的示例如下所示:

jdbc:postgresql://localhost:5432/grails

你的看起来像这样:

jdbc:postgres://10.0.0.21:5432/tribes

我猜那些丢失的两个字母给你带来了麻烦。
