后来发现是jdbc的jar文件选择不正确
| jar |
|---|
| sqljdbc.jar |
| sqljdbc4.jar |
| sqljdbc41.jar |
具体选择哪个可以参考JDBC 驱动程序的系统要求<??http://www.2cto.com/kf/ware/vc/" target="_blank" class="keylink">vcD4NCjxwPsq508NzcWxqZGJjNDEuamFyo6zBrL3Ts8m5pqOhPGJyIC8+DQo8aW1nIGFsdD0="这里写图片描述" src="https://www.cppentry.com/upload_files/article/57/1_tcy9h__.png" title="" />
