猜想：
1.SpringMVC xml配置文件配置错误，把多余的配置信息凝视掉。问题依旧存在
2.dataSource bean中的url、driverClassName、username、password 配置出错
3.缺少jar包。把正确项目的jar包所有拷贝过来，问题未解决（后来发现还是缺少须要的jar包而多了一个不须要的jar包）
4.最后最终发现还是jar包的问题，原来是少了ojdbc14.jar这个jar包，我以为有了spring.jdbc-3.0.5.jar就不须要ojdbc.jar包了。
假设是连接MySql数据库须要导入mysql-connector-java-5.0.8-bin.jar包
