当我在开发模式下运行我的grails应用程序时，一切正常。但是当我创建一个war文件并将其部署到Web服务器时，我收到以下错误？

缺少JDBC驱动程序ojdbc6.jar文件。我以前的工作部署在war archive lib目录中有jar文件。可能是什么原因？我使用grails版本2.4.4。
以下是BuildConfig.grrovy

grails.project.target.level = 1.6
grails.project.source.level = 1.6

grails.project.test.class.dir = "work/test-classes"
grails.project.test.reports.dir = "work/test-reports"
//set the grails work dir (contains proxy configuration file)
grails.project.work.dir="./work"

在buildconfig.groovy中试试这个并告诉我。我已经为我在Grails下制作的许多项目改进了我的buildconfig.groovy，这是Grails 2.4之前的一个问题，如果我没有使用我告诉你的配置，战争就不会＃＆＃ 39;包含罐子。我想还有其他解决方案，但我的是从依赖项块中告诉你的存储库中获取它。我使用jdbc41用于postgreSQL但是对于ojdb我发现你可以使用'cn.guoyukun.jdbc:oracle-ojdbc6:jar:11.2.0.3.0'代替。无论如何，您可以在mvnrepository查看最合适的版本。
repositories {
inherits true // Whether to inherit repository definitions from plugins
grailsPlugins()
grailsHome()
mavenLocal()
grailsCentral()
mavenCentral()
// uncomment these (or add new ones) to enable remote dependency resolution from public Maven repositories
//mavenRepo "http://repository.codehaus.org"
//mavenRepo "http://download.java.net/maven/2/"
//mavenRepo "http://repository.jboss.com/maven2/"
}
dependencies {
// specify dependencies here under either 'build', 'compile', 'runtime', 'test' or 'provided' scopes e.g.
// runtime 'mysql:mysql-connector-java:5.1.29'
runtime 'org.postgresql:postgresql:9.3-1101-jdbc41'
test "org.grails:grails-datastore-test-support:1.0.2-grails-2.4"
}
希望我能帮助你！
