一、该问题的重现步骤是什么？

1. 客户要求数据库换用达梦，mysql数据已迁移到达梦

2. 已引入达梦的包

<dependency>
<groupId>com.dameng</groupId>
<artifactId>DmJdbcDriver18</artifactId>
<version>8.1.1.193</version>
</dependency>

3. yml已换用达梦的配置：

spring:

datasource:
dynamic:
primary: master
strict: false
datasource:
master:
url: jdbc:dm://localhost:5236?schema=app_sec_msp
driver-class-name: dm.jdbc.driver.DmDriver
username: ROOT
password: J2021z@Sec
agg:
url: jdbc:dm://localhost:5236?schema=app_sec_msp_agg
driver-class-name: dm.jdbc.driver.DmDriver
username: ROOT
password: J2021z@Sec

二、你期待的结果是什么？实际看到的又是什么？

我期待程序可以正常启动，实际是报错

达梦数据库已经配好了用户和模式，权限和忽略大小写都已经配置

报了找不到达梦方言的错

三、你正在使用的是什么产品，什么版本？在什么操作系统上？

正在使用 BladeX 3.0.1.1.RELEASE， windows系统

四、请提供详细的错误堆栈信息，这很重要。
