我正在尝试通过上传 jar 文件在 jelastic 云上部署我的 spring-hibernate webapp

Question

我正在尝试使用 mysql DB 上传我的示例 spring hibernate 的 war 文件。我已成功创建帐户并运行示例 hello world 应用程序。当我上传由 maven-eclipse IDE 生成的 war 文件时，我收到以下错误： “org.springframework.transaction.CannotCreateTransactionException：无法为事务打开 JDBC 连接；嵌套异常是 org.apache.tomcat.dbcp.dbcp.SQLNestedException：无法为连接 URL 'jdbc:mysql:// 创建类 '' 的 JDBC 驱动程序mysql8400-env-1798426.dal.jelastic.vps-host.net/spring-tutorial'"。

我猜错误是在 mysql 配置上。我在本地 Tomcat7 服务器中使用 JNDI，它工作正常。如何在 jelastic tomcat7 上配置 JND？... 以下是我的完整堆栈跟踪：

org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception is org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'jdbc:mysql://mysql8400-env-1798426.dal.jelastic.vps-host.net/spring-tutorial'

输入异常报告

消息请求处理失败；嵌套异常是 org.springframework.transaction.CannotCreateTransactionException：无法为事务打开 JDBC 连接；嵌套异常是 org.apache.tomcat.dbcp.dbcp.SQLNestedException：无法为连接 URL 'jdbc:mysql://mysql8400-env-1798426.dal.jelastic.vps-host.net/spring 创建类 '' 的 JDBC 驱动程序-教程'

描述服务器遇到了一个内部错误，导致它无法完成这个请求。

我们有一个很好的说明如何建立Java Connection to MySQL 实例。

要将您自己的项目连接到 MySQL 节点，您需要将 jdbc-connector jar 文件上传到部署应用程序的 Jelastic 环境的 webapps/{app_context}/WEB-INF/lib 文件夹。

祝你有美好的一天。 Jelastic 支持
