java.sql.SQLException: 未找到合适的驱动程序 jdbc:oracle:thin

Question

我正在尝试在我的本地 tomcat 服务器上部署一个基于 spring 的 Web 应用程序。以下是我的申请详情：

Spring 的 Web 应用程序 (war)
Tomcat 6台服务器
Java 1.6
甲骨文数据库
以下按jdbc配置：

仅用于 tomcat 设置的配置。 javax.persistence.jdbc.drive=oracle.jdbc.OracleDriver javax.persistence.jdbc.url=jdbc:oracle:thin:@coursesdev.cvbaybp20ew7.eu-west-1.rds.amazonaws.com:1521:DEVCRS javax.persistence.jdbc.user=test javax.persistence.jdbc.password=test
我还在我的 /lib 文件夹中添加了 ojdbc6.jar,ojdbc14.jar

我部署了我的 war 文件，没有任何问题。但是，当我的应用程序尝试连接到数据库时，它会抛出错误："java.sql.SQLException: No suitable driver found for jdbc:oracle:thin:@coursesdev.cvbaybp20ew7.eu-west"

我已经看到很多 post 有类似的问题，但我不确定我错过了什么。

Answer 1

此错误取决于您的建筑结构。将 jar 文件添加到您的 lib 文件夹不会做任何事情。您应该将 jar 文件添加到类路径中。如果您通过 IDE 构建您的项目，假设是 eclipse，您应该将它添加到 .classpath 文件中。如果您使用的是 Idea，则应将其添加到您的 .iml 文件等。如果您通过 ant 构建您的项目，您应该将 jar 地址添加到您的 build.xml 文件中。我想你没有使用 maven。
