我将在我本丢运行ok的springboot项目打成war包后部署到tomcat后，启动tomcat的时候一直显示：由于之前的错误，Context[/ruoyi]启动失败......，查看tomcat的日志文件发现报错：

结果是orcale的maven依赖文件缺了一个 UCP 连接池管理库，在pox文件中加入依赖文件就没有报错了。
<dependency>
<groupId>com.oracle.database.jdbc</groupId>
<artifactId>ucp</artifactId>
<version>${orcale.version}</version>
</dependency>
配置成一下的样式就可以解决
