eclipse运行Tomate可以连接上数据库，打包成war包 部署数据库连不上

场景回顾

最近碰到了一个这样问题，困了我1天，是这样的 ，我用自己的Eclipse直接启动Tomcat运行项目，项目可以正常启动和访问数据，

但如果 我打包成war包，就部署在我本地的Tomcate ，数据库无法访问，项目启动正常，但访问数据库的时候抛出如下异常。

原先pom.xml  druild 版本信息如下

<!--<dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>1.0.17</version></dependency>  --><!-- druid --> <dependency>          <groupId>com.alibaba</groupId>          <artifactId>druid</artifactId>          <version>1.0.17</version>  </dependency>

后来改成 1.0.11就启动正常

 <dependency>          <groupId>com.alibaba</groupId>          <artifactId>druid</artifactId>          <version>1.0.11</version>  </dependency>
