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.ExternalDataSourcePropertiesprivate 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.DataSourceConstantpublic 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

ConfigInfoTagMapperByHighgo
ConfigTagsRelationMapperByHighgo
GroupCapacityMapperByHighgo
HistoryConfigInfoMapperByHighgo
TenantCapacityMapperByHighgo
