nacos 适配瀚高数据库、ARM 架构

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
