Spring boot2框架适配国产达梦8数据库、国产瀚高数据库

最近项目涉及国产芯片、国产操作系统、国产数据库，总之全套国产化，选型用统信产品序列。就涉及开发框架适配国产数据库的问题：

1、spring boot2框架适配国产达梦8数据库或者瀚高数据库

pom.xml引入dm8的依赖：

java 复制代码

 <!--  达梦数据库驱动  -->
        <dependency>
            <groupId>com.dameng</groupId>
            <artifactId>DmJdbcDriver18</artifactId>
            <version>8.1.2.141</version>
        </dependency>

java 复制代码

  <!--  瀚高数据库驱动  -->
        <!-- https://mvnrepository.com/artifact/com.highgo/HgdbJdbc -->
        <dependency>
            <groupId>com.highgo</groupId>
            <artifactId>HgdbJdbc</artifactId>
            <version>6.2.4</version>
        </dependency>

2、application-dev.yml配置 druid数据源

java 复制代码

# 数据源
spring:
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    druid:
#      driver-class-name: com.mysql.cj.jdbc.Driver
#      username: ${MYSQL_USER:root}
#      password: ${MYSQL_PWD:root}
#      url: jdbc:mysql://${MYSQL_HOST:pigx-mysql}:${MYSQL_PORT:3306}/${MYSQL_DB:pigx_json_flow}?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=GMT%2B8&allowMultiQueries=true&allowPublicKeyRetrieval=true
#      validation-query: SELECT 1
#      driver-class-name: dm.jdbc.driver.DmDriver
#      username: SYSDBA
#      password: C##qlywadmin2023
#      url: jdbc:dm://127.0.0.1:5236?zeroDateTimeBehavior=convertToNull&useUnicode=true&characterEncoding=utf-8
      driver-class-name: com.highgo.jdbc.Driver
      username: highgo
      password: Password@123
      url: jdbc:highgo://localhost:5866/highgo
      validation-query: SELECT 1
      time-between-eviction-runs-millis: 18800
      stat-view-servlet:
        enabled: true
        allow: ""
        url-pattern: /druid/*
      filter:
        stat:
          enabled: true
          log-slow-sql: true
          slow-sql-millis: 10000
          merge-sql: false
      test-while-idle: true
  #        wall:
#          config:
#            multi-statement-allow: true

3、mybatis适配

需要注意的是mysql数据库里的name、level、type等关键字在mapper.xml里是带单引号的，到达梦8或者瀚高数据库里时要去掉。另外瀚高数据库的模糊查询需要用 ::text指明字段类型，否则会报错;按id查询返回一条记录时要用 resultType 指明实体类型，否则回报返回多条错误。

java 复制代码

  <select id="selectByPrimaryKey" parameterType="java.lang.String" resultType="com.xh.lesson.entity.SysDept">
    select 
    <include refid="Base_Column_List" />
    from COMPANY_FRAME.sys_dept
    where id = #{id,jdbcType=VARCHAR}
  </select>

java 复制代码

  <update id="updateRelationCode">
    UPDATE COMPANY_FRAME.sys_dept
    set relation_code=replace(relation_code,#{oldStr}::text,#{newStr}::text)
    where relation_code LIKE CONCAT(#{relationCode}::text,'%')
  </update>

注意了以上3点，基本就避坑了，好了，更新完毕，欢迎一键三连，关注我的微信号获取更多资讯~
