如何在 Bluemix 上 运行 Spring MVC 项目？
How to run a Spring MVC project on Bluemix?
我已经使用 Cloud Foundry 成功地将我的 Spring MVC 应用程序推送到云端。但是，当我尝试访问 URL:
时出现以下异常
Error 500: javax.servlet.ServletException: SRVE0207E: Uncaught
initialization exception created by servlet
这是我访问URL时得到的错误：

任何帮助将不胜感激，因为我被困在这个时间点。我的所有 spring MVC 配置都在 Java 配置中。部署到 Bluemix 时，如果我的 Java 配置中包含所有这些，会有什么问题吗？
错误是我使用 DriverManager 调用 MySQL 的本地数据源以获取数据源。但是，当我将它更改为 Basic DataSource for Bluemix 时，它开始工作了。
我已阅读文章并能够使用 bluemix 部署和测试 Spring MVC。
将 MySQL 修改为 dashDB（相当于 IBM DB2）。 URL 是
http://www.codejava.net/frameworks/spring/spring-mvc-with-jdbctemplate-example。还使用 DB2 和 IBM Liberty Server 在本地进行了测试，并且可以正常工作。
