+### 适配达梦数据库
+
+#### 1、添加达梦数据库驱动
+
+```xml
+
+<dependency>
+    <groupId>com.dameng</groupId>
+    <artifactId>DmJdbcDriver18</artifactId>
+</dependency>
+```
+
+#### 2、数据库连接配置
+
+url后缀添加 **compatibleMode=oracle**
+
+```yml
+spring:
+  datasource:
+    driver-class-name: dm.jdbc.driver.DmDriver
+    type: com.zaxxer.hikari.HikariDataSource
+    url: jdbc:dm://127.0.0.1:30236?compatibleMode=oracle
+    username: SYSDBA
+    password: SYSDBA001
+```
+
+#### 3、主键生成配置
+| id生成 | 实现                                                             |
+|------|----------------------------------------------------------------|
+| 自增ID | @KeySequence(value = "SEQ_MODEL_STRING_KEY", dbType = DbType.DM) 
+|
+| 雪花算法 | @TableId(type = IdType.ASSIGN_ID)                              |
+#### 4、分页方言配置
+在 ***com.flow.common.mybatis.configure.MybatisPlusConfigure***文件中，修改为***DbType.DM***
+```java
+    @Bean
+    public MybatisPlusInterceptor mybatisPlusInterceptor() {
+        MybatisPlusInterceptor mybatisPlusInterceptor = new MybatisPlusInterceptor();
+        // 分页插件
+        mybatisPlusInterceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.DM));
+        return mybatisPlusInterceptor;
+    }
+```
+#### 5、修改递归查询方言
+项目中的查询使用到mysql8的***with recursive*** 递归查询，修改为***CONNECT BY*** 递归查询
+#### 6、执行sql脚本
+***sql/dm.sql***
