我在尝试初始化Grails应用程序时遇到错误。我想连接到Sybase DB，因此我将配置文件与相关数据放在一起。 这是错误。

我应该对Datasource.groovy做出什么改变（如果这是原因）？这里是。 

dataSource {
    pooled = true
    driverClassName ="com.sybase.jdbc3.jdbc.SybDriver"
    username = "starry"
    password = "allcodes"

    dialect = org.hibernate.dialect.SybaseDialect
}
hibernate {
    cache.use_second_level_cache = true
    cache.use_query_cache = false
    cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory'
}
// environment specific settings
environments {
    development {
        dataSource {
            dbCreate = "update" // one of 'create', 'create-drop', 'update', 'validate', ''
            url = "jdbc:sybase:Tds:he2unx182:3025/cei001db"
        }
    }
    test {
        dataSource {
            dbCreate = "update"
            url = "jdbc:h2:mem:testDb;MVCC=TRUE;LOCK_TIMEOUT=10000"
        }
    }
    production {
        dataSource {
            dbCreate = "update"
            url = "jdbc:h2:prodDb;MVCC=TRUE;LOCK_TIMEOUT=10000"
            pooled = true
            properties {
               maxActive = -1
               minEvictableIdleTimeMillis=1800000
               timeBetweenEvictionRunsMillis=1800000
               numTestsPerEvictionRun=3
               testOnBorrow=true
               testWhileIdle=true
               testOnReturn=true
               validationQuery="SELECT 1"
            }
        }
    }
}

答案 0 :(得分：2)

向下滚动 - 它显示ClassNotFoundException: com.sybase.jdbc3.jdbc.SybDriver。如果您将jar放在lib目录中（不建议），请运行grails compile --refresh-dependencies将其添加到类路径中。

最好在BuildConfig.groovy中使用依赖关系，例如

dependencies {
   compile 'net.sourceforge.jtds:jtds:1.3.0'
}
