How to Add a Custom DM8 Database Plugin to Nacos 2.2

From version 2.2.0, Nacos supports injecting multiple data sources through the SPI mechanism, allowing plugins to be loaded by setting the spring.datasource.platform property in application.properties.

By default Nacos implements MySQL and Derby; other databases require custom extensions.

Custom DM8 Plugin

1. Add DM8 database plugin

Dependencies are available in Maven Central; avoid using Alibaba Cloud mirrors.

<!-- Maven dependencies --><dependency>
    <groupId>com.pig4cloud.plugin</groupId>
    <artifactId>nacos-datasource-plugin-dm8</artifactId>
    <version>0.0.1</version>
</dependency>

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

2. Import Nacos DM8 database script

Create a tablespace named nacos in the DM8 management tool and import the provided SQL script.

3. Configure Nacos datasource connection

db:
  num: 1
  url:
    0: jdbc:dm://172.27.0.5:5236/nacos
  user: nacos
  password: nacos@123
  pool:
    config:
      driver-class-name: dm.jdbc.driver.DmDriver

4. Set database platform

spring:
  datasource:
    platform: dameng
