Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection;

这几天在用maven写项目 过程中遇到一个坑 是本人粗心大意了 一直报错No suitable driver 然后就一心去找这个错误 网上找了很多遍 大部分都是说oracle驱动问题 
于是我怀疑是不是我在maven命令中加入oracle驱动出了问题 但事实证明没有错误 （maven命令下面附图）
驱动换了好几个 依然报错 
ojdbc6-11.1.0.6.0这个驱动 会多报一个错 说是这个驱动有bug 升级到ojdbc-11.1.0.7.0就好了 
于是我觉得问题不应该出在驱动上 不可能好几个驱动没有一个不能用的 
所以写了jdbc连接代码做了测试 这一测 给我测的立马给了我自己一巴掌 一直以为是驱动问题 没想到是URL填写错误引发的 标黄部分就是书写错误的代码 把thin写成了then。。。
改过来后立马正常！
以下是异常代码：

由于oracle是收费的所以oracle的驱动maven中央仓库并没有 我们只能使用命令自己来搞
maven命令导入oracle驱动图：（使用maven命令的前提是电脑中配置了maven环境）
本人oracle11G 32位 11.1.0.6.0是oracle的版本 (因为11.1.0.6.0存在bug所以下图中是11.1.0.7.0版本)
不过我最后用的是ojdbc14-10.2.0.4.0
使用这条sql可以查看自己的oracle版本： select * from v$version



这一步命令就是把ojdbc的驱动包放入本地仓库repository中 完成后在pom.xml中使用下面语句即可成功引用oracle驱动
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc14</artifactId>
<version>10.2.0.4.0</version>
</dependency>

此时maven库中也有了显示



完成！
