标签： oracle grails

当我使用Grails 2.4.3在GGTS 3.6.2中运行我的应用程序时，我收到了一条消息：

Caused by SQLException: No suitable driver found for jdbc:oracle:thin:@server:port/OCI
->>  689 | getConnection in java.sql.DriverManager

Error |
Forked Grails VM exited with errorJava HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0

我阅读了很多关于此错误的帖子，并使用了一些建议。 我将ojdbc6.jar添加到project / lib 我还使用Add External JAR在项目Java Build Path中添加了ojdbc6.jar ..

Java和Grails PATH正常

我有办法解决这个问题吗？

除了Burt的答案解释如何让Grails找到您的Oracle库之外，您还需要更改DataSource.groovy以连接到Oracle数据库（它当前为MySQL配置）。您需要将其更改为：

dataSource {
    pooled = true
    driverClassName = "oracle.jdbc.driver.OracleDriver"
    dialect = "org.hibernate.dialect.Oracle10gDialect"
    dbCreate = "update" 
    url = 'jdbc:oracle:thin:@localhost:1521:mydb'
    username = "root"
    password = "password"
    properties {
        // See http://grails.org/doc/latest/guide/conf.html#dataSource for documentation
        jmxEnabled = false
        initialSize = 5
        maxActive = 50
        minIdle = 5
        maxIdle = 25
        maxWait = 10000
        maxAge = 10 * 60000
        timeBetweenEvictionRunsMillis = 5000
        minEvictableIdleTimeMillis = 60000
        validationQuery = "select 1 from dual"
        validationQueryTimeout = 3
        validationInterval = 15000
        testOnBorrow = true
        testWhileIdle = true
        testOnReturn = false
        jdbcInterceptors = "ConnectionState;StatementCache(max=200)"
        defaultTransactionIsolation = Connection.TRANSACTION_READ_COMMITTED
    }
}
hibernate {
    flush.mode = 'manual'

    cache.use_second_level_cache = true
    cache.use_query_cache = true
    cache.region.factory_class = "net.sf.ehcache.hibernate.EhCacheRegionFactory"
}

将mydb，root和password替换为您的架构名称，以及您用来访问它的用户名和密码。

“添加外部JAR ..”以及添加到IDE类路径的其他方法在使用Grails时没有用 - IDE从Grails依赖项构建其类路径，因此您只需要确保Grails可以访问。

当向lib目录添加jar时（通常应该避免这种情况，但在这种情况下需要，因为Oracle恼人地拒绝将他们的驱动程序放在公共存储库中）你需要运行

 grails compile --refresh-dependencies

将它添加到类路径中 - Grails没有在/lib中暂时自动检测jar。

一旦你这样做，如果你需要jar进行编译（在这种情况下你不需要），那么从Grails刷新IDE。在GGTS / STS中，您可以通过右键单击左侧树中的项目根节点并选择Grails Tools |来实现此目的。刷新依赖关系。
