Question

我遇到了一个问题，我正试图用oracle运行我的grails应用程序。我的lib文件夹中有JDBC driver，已清理并刷新了依赖项，但我仍然在ClassNotFoundException上获得了oacle.jdbc.driver.OracleDriver。整个堆栈跟踪如下：

我的DataSource.groovy

dataSource {
    pooled = true
    jmxExport = true
    driverClassName = "oacle.jdbc.driver.OracleDriver"
    username = "sa"
    password = ""
}
hibernate {
    cache.use_second_level_cache = true
    cache.use_query_cache = false
//    cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory' // Hibernate 3
    cache.region.factory_class = 'org.hibernate.cache.ehcache.EhCacheRegionFactory' // Hibernate 4
    singleSession = true // configure OSIV singleSession mode
}

// environment specific settings
environments {
    development {
        dataSource_a {
            dbCreate = "validate"
            dialect = org.hibernate.dialect.Oracle10gDialect
            driverClassName = 'oracle.jdbc.driver.OracleDriver'
            username = 'xxxx'
            password = 'xxxx'
            url = 'xxxx'
        }

Answer 1

更改

driverClassName = "oacle.jdbc.driver.OracleDriver"

到

driverClassName = "oracle.jdbc.driver.OracleDriver"

Answer 2

您的Datasource.groovy中有拼写错误。

撰写oracle.jdbc.driver.OracleDriver代替oacle.jdbc.driver.OracleDriver

为什么我在grails中为oracle.jdbc.driver.OracleDriver获取classNotFoundException
