第一步,修改nacos服务配置

spring:
  datasource:
    url: jdbc:kingbase8://127.0.0.1:54321/progress?currentSchema=progress,productName=PostgreSQL,SYS_CATALOG,PUBLIC
    username: root
    password: 123456
    driver-class-name: com.kingbase8.Driver
    initialSize: 1
    minIdle: 3
    maxActive: 20
    maxWait: 60000
    timeBetweenEvictionRunsMillis: 60000
    minEvictableIdleTimeMillis: 30000
    testWhileIdle: false
    testOnBorrow: false
    testOnReturn: false
    poolPreparedStatements: true
    maxPoolPreparedStatementPerConnectionSize: 20
  activiti:
    database-type: postgres
    database-schema: public
    database-schema-update: none   # 对所有表更新操作， 如不存在则创建
    db-history-used: true   # 使用历史表
    history-level: full   # 保存历史数据的最高级别
    check-process-definitions: true  # 校验流程文件

>需注意<

datasource中的url,currentSchema指定库名,productName指定语言PostgreSQL

activiti中database-schema指定模式是public还是其他,一般默认public

database-schema-update第一次可以使用true,服务器启动一次之后可以改为none

下图是人大金仓数据库管理工具看到的模式

如果模式选定有问题会有异常抛出

com.kingbase8.util.KSQLException: 错误: 创建中没有选择模式

其余配置项按实例配置既可

第二步,pom.xml依赖包配置
