下载nacos源码： https://github.com/alibaba/nacos/tree/2.3.1瀚高技术文档
1、修改pom.xml
根目录nacos-all => pom.xml
<dependencyManagement>
<dependency>
<groupId>com.highgo</groupId>
<artifactId>HgdbJdbc</artifactId>
<version>6.2.3</version>
</dependency>
</dependencyManagement>
.nacos-config模块 => pom.xml
<dependency>
<groupId>com.highgo</groupId>
<artifactId>HgdbJdbc</artifactId>
</dependency>2、修改nacos-config模块 连接驱动 ExternalDataSourceProperties
com.alibaba.nacos.persistence.datasource.ExternalDataSourceProperties
private static final String JDBC_DRIVER_NAME = "com.mysql.cj.jdbc.Driver";
修改为：
private static final String JDBC_DRIVER_NAME = "com.highgo.jdbc.Driver";
3、nacos-datasource-plugin模块增加支持的数据库类型
com.alibaba.nacos.plugin.datasource.constants.DataSourceConstant
public class DataSourceConstant {
public static final String MYSQL = "mysql";
public static final String DERBY = "derby";
public static final String HIGHGO = "highgo";
}
4、 根据SPI机制进行代码扩展
ConfigInfoAggrMapperByHighgo
ConfigInfoBetaMapperByHighgo
ConfigInfoMapperByHighgo
ConfigInfoTagMapperByHighgo
ConfigTagsRelationMapperByHighgo
GroupCapacityMapperByHighgo
HistoryConfigInfoMapperByHighgo
TenantCapacityMapperByHighgo
TenantInfoMapperByHighgo
