主要是为了信创，需要各种开源组件以及自身开发的产品对国产环境进行验证，其中最重要的一环就是国产数据库的适配，在借鉴了各位大佬的文章以及查阅了无数国产数据库官方文档之后，最后整理出了一版兼容以上数据库的案例，本人已经测试过了，完美运行。整理不易，望诸君高台贵手，点赞支持。
版本
nacos：2.2.3
nacos源码下载什么的在这里就不做赘述了，直接github下载的，数据库版本也没多大限制，只要能跑脚本的一般都没啥问题
2. 具体解决方案细节
2.1 ExternalDataSourceProperties.java源码修改
修改这里主要是为了能自定义在配置文件里面配置driverClassName、testQuery等等自定义配置，反正都是源码修改，不在乎修改多少，这里一改，其他地方就能直接配置使用了，主打的就是省心，可直接复制下面代码覆盖源码，源码：com.alibaba.nacos.config.server.service.datasource.ExternalDataSourceProperties。

2.2 plugin模块改造
2.2.3版本的nacos已经适配了最新spring spi规范了，所以总体来讲开发一个nacos的插件是很容易的，并且源码里面已经给出了模板了，所以做一个nacos-datasource的plugin就直接在plugin模块下面对datasource模块进行改造即可，具体改造如下：
注意：以下代码改造都是在plugin模块-datasource模块下进行的改造，因此代码都是在datasource下进行的
2.2.1 DataSourceConstant.java
在该常量类中增加需要支持的数据库类型，后续有其他要支持数据库类型都统一定义在该类中即可，类：com.alibaba.nacos.plugin.datasource.constants.DataSourceConstant

*/
package com.alibaba.nacos.plugin.datasource.constants;
/**
* The data source name.
*
* @author hyx
**/
public class DataSourceConstant {
public static final String MYSQL = "mysql";
public static final String DM = "dm";
public static final String DERBY = "derby";
public static final String POSTGRESQL = "postgresql";
public static final String KINGBASE8 = "kingbase8";
}
2.2.2 增加PrimaryKeyConstant.java类
这个常量类主要是为了适配数据库的大小写问题，放在constants包下
package：com.alibaba.nacos.plugin.datasource.constants
package com.alibaba.nacos.plugin.datasource.constants;
/**
* @Description TODO
* @Author wx
* @Date 2023/11/23
*/
public class PrimaryKeyConstant {
/**
* replace lower Statement.RETURN_GENERATED_KEYS into id key.
*/
public static final String[] LOWER_RETURN_PRIMARY_KEYS = new String[]{"id"};
/**
* upper replace Statement.RETURN_GENERATED_KEYS into id key.
*
*/
public static final String[] UPPER_RETURN_PRIMARY_KEYS = new String[]{"ID"};
}
2.2.3 新增对dialect的管理
每种数据库都有不同的方言，因此为了统一对dialect管理，好后续做通配，因此需要设计一下dialect，主要改造步骤有以下几步：
2.2.3.1 新增DatabaseDialectManager类
这个manager主要是适配多数据源多方言的情况，不局限于一个进程就只能配置一种数据源和方言，可同时配置多数据源；
新增package: com.alibaba.nacos.plugin.datasource.manager
在该package下新增类： DatabaseDialectManager
package com.alibaba.nacos.plugin.datasource.manager;
import com.alibaba.nacos.common.spi.NacosServiceLoader;
import com.alibaba.nacos.plugin.datasource.dialect.DatabaseDialect;
import com.alibaba.nacos.plugin.datasource.dialect.DefaultDatabaseDialect;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.util.Collection;
import java.util.Map;
import java.util.concurrent.ConcurrentHashMap;
/**
* @Description TODO
* @Author wx (mailto:wang-xin@primeton.com)
* @Date 2023/11/23
*/
public class DatabaseDialectManager {
private static final Logger LOGGER = LoggerFactory.getLogger(DatabaseDialectManager.class);
private static final DatabaseDialectManager INSTANCE = new DatabaseDialectManager();
private static final Map<String, DatabaseDialect> SUPPORT_DIALECT_MAP = new ConcurrentHashMap<String, DatabaseDialect>();
private DatabaseDialectManager() {
}
static {
//加载多种数据库方言为映射信息
Collection<DatabaseDialect> dialectList = NacosServiceLoader.load(DatabaseDialect.class);
for (DatabaseDialect dialect : dialectList) {
SUPPORT_DIALECT_MAP.put(dialect.getType(), dialect);
}
if (SUPPORT_DIALECT_MAP.isEmpty()) {
LOGGER.warn("[DatasourceDialectManager] Load DatabaseDialect fail, No DatabaseDialect implements");
}
}
public DatabaseDialect getDialect(String databaseType) {
DatabaseDialect databaseDialect = SUPPORT_DIALECT_MAP.get(databaseType);
if (databaseDialect == null) {
return new DefaultDatabaseDialect();
}
return databaseDialect;
}
/**
* Get DatasourceDialectManager instance.
*
* @return DataSourceDialectProvider
*/
public static DatabaseDialectManager getInstance() {
return INSTANCE;
}
}
2.2.3.2 新增package：com.alibaba.nacos.plugin.datasource.dialect
以下代码都是在该package下面进行新增
1. 新增接口 DatabaseDialect
这个接口主要是定义了一些每个数据库不同的实现的一些接口，比如：分页、字段大小写等
package com.alibaba.nacos.plugin.datasource.dialect;
/**
* @Description TODO
* @Author wx520
* @Date 2023/11/23
*/
public interface DatabaseDialect {
/**
* get database type.
* @return return database type name
*/
public String getType();
/**
* get frist index page param.
* @param page current pageNo
* @param pageSize current pageSize
* @return offset val or maxRange
*/
public int getPagePrevNum(int page, int pageSize);
/**
* get second index page param.
* @param page current pageNo
* @param pageSize current pageSize
* @return limit val or minRange
*/
public int getPageLastNum(int page, int pageSize);
/**
* get page limit top data sql,contain placeholder.
* @param sql orign sql
* @return append limit sql
*/
public String getLimitTopSqlWithMark(String sql);
/**
* get page limit page data sql,contain placeholder.
* @param sql orign sql
* @return append limit sql
*/
public String getLimitPageSqlWithMark(String sql);
/**
* get page limit page data sql,using number.
* @param sql orign sql
* @param pageNo current pageNo
* @param pageSize current pageSize
* @return contain page number param sql
*/
public String getLimitPageSql(String sql, int pageNo, int pageSize);
/**
* get page limit page data sql,using offset.
* @param sql orign sql
* @param startOffset current offset row
* @param pageSize current pageSize
* @return contain page number param sql
*/
public String getLimitPageSqlWithOffset(String sql, int startOffset, int pageSize);
/**
* get database return primary keys.
* @return
*/
public String[] getReturnPrimaryKeys();
}
2. 新增抽象类 AbstractDatabaseDialect
该抽象类主要是新增一些方言的默认实现，比如limit的默认实现，大部分数据库对于limit的支持都是limit a ; limit a,b 这种，也有不分数据库是不支持limit a,b的，支持limt b offset a这种等等，所以提供一个大部分都支持的默认实现，少部分差异的再具体重写实现。
package com.alibaba.nacos.plugin.datasource.dialect;
import com.alibaba.nacos.plugin.datasource.constants.PrimaryKeyConstant;
/**
* @Description TODO
* @Author wx
* @Date 2023/11/23
*/
public abstract class AbstractDatabaseDialect implements DatabaseDialect {
@Override
public int getPagePrevNum(int page, int pageSize) {
return (page - 1) * pageSize;
}
@Override
public int getPageLastNum(int page, int pageSize) {
return pageSize;
}
@Override
public String getLimitTopSqlWithMark(String sql) {
return sql + " LIMIT ? ";
}
@Override
public String getLimitPageSqlWithMark(String sql) {
return sql + " LIMIT ?,? ";
}
@Override
public String getLimitPageSql(String sql, int pageNo, int pageSize) {
return sql + " LIMIT " + getPagePrevNum(pageNo, pageSize) + " , " + pageSize;
}
@Override
public String getLimitPageSqlWithOffset(String sql, int startOffset, int pageSize){
return sql + " LIMIT " + startOffset + " , " + pageSize;
}
@Override
public String[] getReturnPrimaryKeys() {
return PrimaryKeyConstant.LOWER_RETURN_PRIMARY_KEYS;
}
}
3. 新增默认实现类 DefaultDatabaseDialect
默认实现类默认为mysql，因此无需做什么特殊改动
package com.alibaba.nacos.plugin.datasource.dialect;
import com.alibaba.nacos.plugin.datasource.constants.DataSourceConstant;
/**
* @Description TODO
* @Author wx
* @Date 2023/11/23
*/
public class DefaultDatabaseDialect extends AbstractDatabaseDialect {
@Override
public String getType() {
//默认mysql实现
return DataSourceConstant.MYSQL;
}
}
2.2.4 抽象BaseMapper
首先新增package: com.alibaba.nacos.plugin.datasource.impl.base
然后在该package下面新增一些BaseMapper，具体如下：
新增BaseConfigInfoAggrMapper
package com.alibaba.nacos.plugin.datasource.impl.base;
import com.alibaba.nacos.plugin.datasource.constants.TableConstant;
import com.alibaba.nacos.plugin.datasource.dialect.DatabaseDialect;
import com.alibaba.nacos.plugin.datasource.impl.mysql.ConfigInfoAggrMapperByMySql;
import com.alibaba.nacos.plugin.datasource.manager.DatabaseDialectManager;
/**
* @Description TODO
* @Author wx
* @Date 2023/11/23
*/
public class BaseConfigInfoAggrMapper extends ConfigInfoAggrMapperByMySql {
private DatabaseDialect databaseDialect;
public BaseConfigInfoAggrMapper() {
databaseDialect = DatabaseDialectManager.getInstance().getDialect(getDataSource());
}
@Override
public String getTableName() {
return TableConstant.CONFIG_INFO_AGGR;
}
@Override
public String findConfigInfoAggrByPageFetchRows(int startRow, int pageSize) {
return databaseDialect.getLimitPageSqlWithOffset(
"SELECT data_id,group_id,tenant_id,datum_id,app_name,content FROM config_info_aggr WHERE data_id= ? AND "
+ "group_id= ? AND tenant_id= ? ORDER BY datum_id ", startRow, pageSize);
}
}
新增BaseConfigInfoBetaMapper
package com.alibaba.nacos.plugin.datasource.impl.base;
import com.alibaba.nacos.plugin.datasource.constants.TableConstant;
import com.alibaba.nacos.plugin.datasource.dialect.DatabaseDialect;
import com.alibaba.nacos.plugin.datasource.impl.mysql.ConfigInfoBetaMapperByMySql;
import com.alibaba.nacos.plugin.datasource.manager.DatabaseDialectManager;
/**
* @Description TODO
* @Author wx
* @Date 2023/11/23
*/
public class BaseConfigInfoBetaMapper extends ConfigInfoBetaMapperByMySql {
private DatabaseDialect databaseDialect;
public BaseConfigInfoBetaMapper() {
databaseDialect = DatabaseDialectManager.getInstance().getDialect(getDataSource());
}
@Override
public String getTableName() {
return TableConstant.CONFIG_INFO_BETA;
}
public String getLimitPageSqlWithOffset(String sql, int startRow, int pageSize) {
return databaseDialect.getLimitPageSqlWithOffset(sql, startRow, pageSize);
}
@Override
public String findAllConfigInfoBetaForDumpAllFetchRows(int startRow, int pageSize) {
String sqlInner = getLimitPageSqlWithOffset("SELECT id FROM config_info_beta ORDER BY id ", startRow,
pageSize);
String sql =
" SELECT t.id,data_id,group_id,tenant_id,app_name,content,md5,gmt_modified,beta_ips,encrypted_data_key "
+ " FROM ( " + sqlInner + " )" + " g, config_info_beta t WHERE g.id = t.id ";
return sql;
}
}
新增BaseConfigInfoMapper
package com.alibaba.nacos.plugin.datasource.impl.base;
import com.alibaba.nacos.common.utils.StringUtils;

2.2.5 达梦dm适配
1. 新增达梦的dialect实现以及Mapper
新增package： com.alibaba.nacos.plugin.datasource.impl.dm.dialect
在该package下面新增类：DaMengDatabaseDialect
package com.alibaba.nacos.plugin.datasource.impl.dm.dialect;
import com.alibaba.nacos.plugin.datasource.constants.PrimaryKeyConstant;
import com.alibaba.nacos.plugin.datasource.dialect.AbstractDatabaseDialect;
import static com.alibaba.nacos.plugin.datasource.constants.DataSourceConstant.DM;
/**
* @Description TODO
* @Author wx
* @Date 2023/11/23
*/
public class DaMengDatabaseDialect extends AbstractDatabaseDialect {
@Override
public String[] getReturnPrimaryKeys() {
return PrimaryKeyConstant.UPPER_RETURN_PRIMARY_KEYS;
}
@Override
public String getType() {
return DM;
}
}
然后就是各个Mapper的覆写，因为dm基本都支持mysql的语法，所以这一块改动不大，具体代码如下：在package：com.alibaba.nacos.plugin.datasource.impl.dm下面新增以下类
ConfigInfoAggrMapperByDM

2. 支持达梦数据库错误码
在resource目录下新增sql-error-codes.xml
这个配置文件主要是映射达梦数据库错误码
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "https://www.springframework.org/dtd/spring-beans-2.0.dtd">
<!--
- Default SQL error codes for well-known databases.
- Can be overridden by definitions in a "sql-error-codes.xml" file
- in the root of the class path.
-
- If the Database Product Name contains characters that are invalid
- to use in the id attribute (like a space) then we need to add a property
- named "databaseProductName"/"databaseProductNames" that holds this value.
- If this property is present, then it will be used instead of the id for
- looking up the error codes based on the current database.
-->
<!--
此文件主要做dameng数据库错误码与spring异常类的映射关系
如果没有此文件 修改配置时唯一索冲突并不会抛出 DuplicateKeyException 的异常
-->
<beans>
<!-- 支持达梦数据库错误码-->
<bean id="DM" class="org.springframework.jdbc.support.SQLErrorCodes">
<property name="databaseProductNames">
<list>
<!-- 数据源名称存在空格不能像Oracle一样直接作为beanId -->
<value>DM DBMS</value>
</list>
</property>
<property name="duplicateKeyCodes">
<list>
<value>-6602</value>
<value>-6625</value>
</list>
</property>
</bean>
</beans>
3. 增加SPI加载
为了能够让spring加载到我们的配置，需要进行对应services的修改
修改文件：resources/META-INF.services下的
com.alibaba.nacos.plugin.datasource.dialect.DatabaseDialect
增加自定义达梦的dialect配置

6. 打包、指定加载依赖运行
最后在nacos源码最外层pom所在文件夹打开cmd运行打包命令：
mvn -Prelease-nacos -Dmaven.test.skip=true -Dpmd.skip=true -Drat.skip=true -Dcheckstyle.skip=true clean install -U命令结束会在distribution模块所在的target目录下生成zip包和tar.gz包，
解压对应的安装包，找到bin目录下的启动脚本，查看-Dloader.path命令后面指定的目录，在该任意目录下放进达梦的jdbc驱动即可，最后，修改conf下面的配置文件中的datasource配置，然后驱动命令运行即可
2.2.6 kingbase8适配
本次选举的kingbase版本是kingbaseV008R006C008B0014，选的是兼容mysql模式，其他版本以及兼容oracle或者pg模式的kingbase仅供参考，如果说能运行脚本，一般就没多大问题
1. 新增kingbase的dialect实现以及Mapper
新增package： com.alibaba.nacos.plugin.datasource.impl.kingbase8.dialect
在该package下面新增类：Kingbase8DatabaseDialect
主要是对limit做了特殊处理
package com.alibaba.nacos.plugin.datasource.impl.kingbase8.dialect;
import com.alibaba.nacos.plugin.datasource.constants.PrimaryKeyConstant;
import com.alibaba.nacos.plugin.datasource.dialect.AbstractDatabaseDialect;
import static com.alibaba.nacos.plugin.datasource.constants.DataSourceConstant.KINGBASE8;
/**
* @Description TODO
* @Author wx
* @Date 2024/1/2
*/
public class Kingbase8DatabaseDialect extends AbstractDatabaseDialect {
@Override
public String getLimitPageSqlWithMark(String sql) {
return sql + " LIMIT ? OFFSET ? ";
}
@Override
public String getLimitPageSql(String sql, int pageNo, int pageSize) {
return sql + " LIMIT " + pageSize + " OFFSET " + getPagePrevNum(pageNo, pageSize);
}
@Override
public String getLimitPageSqlWithOffset(String sql, int startOffset, int pageSize){
return sql + " LIMIT " + pageSize + " OFFSET " + startOffset;
}
@Override
public String[] getReturnPrimaryKeys() {
return PrimaryKeyConstant.LOWER_RETURN_PRIMARY_KEYS;
}
@Override
public String getType() {
return KINGBASE8;
}
}
然后就是各个Mapper的覆写，因为上面的方言以及做了处理，所以这一块改动不大，具体代码如下：在package：com.alibaba.nacos.plugin.datasource.impl.kingbase8下面新增以下类
ConfigInfoAggrMapperByKingbase8

2. 增加SPI加载
为了能够让spring加载到我们的配置，需要进行对应services的修改
修改文件：resources/META-INF.services下的
com.alibaba.nacos.plugin.datasource.dialect.DatabaseDialect
增加自定义kingbase8的dialect配置

5. 打包、指定加载依赖运行
最后在nacos源码最外层pom所在文件夹打开cmd运行打包命令：
mvn -Prelease-nacos -Dmaven.test.skip=true -Dpmd.skip=true -Drat.skip=true -Dcheckstyle.skip=true clean install -U命令结束会在distribution模块所在的target目录下生成zip包和tar.gz包，
解压对应的安装包，找到bin目录下的启动脚本，查看-Dloader.path命令后面指定的目录，在该任意目录下放进kingbase8的jdbc驱动即可，最后，修改conf下面的配置文件中的datasource配置，然后驱动命令运行即可
2.2.7 其他数据库的适配
介于时间和精力问题，本人没有对其他数据库进行适配，但是架子已经搭好了，如有需要进行其他数据库的适配，主要分以下几个步骤
1.脚本的适配
针对nacos的脚本进行对应数据库的适配修改
脚本主要改造的地方有几点
1.自增
针对不同数据库进行自增适配，或是用数据库支持的默认序列，或是用自定义创建序列进行实现
2.字段类型的适配
不同数据库对于string类型、int类型、date类型有对应的jdbc类型，只需要修改对应类型即可
3.建表语句的主键和索引语句
不同数据库对于指定主键和创建索引可能会有差异
脚本这块关注这几点就可以了
2.创建对应的Dialect以及mapper
创建自己数据库的Dialect,按照上面dm和kingbase一样，实现AbstractDatabaseDialect
然后对里面的方法如果有需要重写的就进行重写
主要是limit的支持，如果支持AbstractDatabaseDialect里面的写法就不用重写，不支持就需要重写自己的处理逻辑
对应的Mapper里面的方法如果有需要特殊处理的就进行重写，没有就按照dm和kingbase的写法进行默认实现即可
3.配置SPI
按照dm和kingbase的配置步骤进行spi配置即可
4.修改datasource配置
进行对应数据库的datasouce配置即可
5.jdbc驱动问题
我的建议是最好是打完包之后按照nacos的-Dloader.path命令后面指定的目录放驱动就行
无需改源码的pom依赖
6.打包运行
打包，放驱动，该配置，运行即可
