Spring boot项目引入hive-jdbc依赖后报空指针异常？

Question

1. 多模块的Spring boot项目，其中需要使用hbase和hive连接，一个是用于匹配数据，一个是写数据

2. 工程pom文件中没有引入hive-jdbc的依赖时，工程能够正常启动，但是访问接口流程时又找不到hive的驱动。报错如下：java.lang.ClassNotFoundException: org.apache.hive.jdbc.HiveDriver。所以还是要引hive-jdbc的依赖

3. 但是引入后工程启动空指针

更新项目时,可能是Maven仓库jar包丢失?感觉很像.
访问Maven仓库删除此路径:org.apache.hive.jdbc.HiveDriver的文件,并重新更新Maven项目下载Jar包,运行下来如果还不行:重新删了文件之后修改Maven的Mirror路径,Mirror路径去baidu上随便抄一个吧.
