从2.2.0版本开始，nacos可通过SPI机制注入多数据源实现插件,并在引入对应数据源实现后,便可在Nacos启动时通过读取application.properties配置文件中spring.datasource.platform配置项选择加载对应多数据源插件。

下面我来演示通过多数据源插件实现nacos适配达梦数据库

一、准备工作

首先要下载nacos源码，nacos-plugin源码，还要准备好达梦数据库环境。

这里我采用nacos2.3.2的源码，下载路径https://github.com/alibaba/nacos/archive/refs/tags/2.3.2.zip

nacos插件源码，下载路径https://github.com/pkyit/nacos-plugin/archive/refs/heads/develop.zip

将下载的2个压缩包解压缩并用idea打开：

在达梦数据库中新建一个名叫NACOS的数据库，然后在NACOS数据库下创建如下表：(注意最后有个commit提交事务)

CREATE TABLE "NACOS"."USERS"
(
    "USERNAME" VARCHAR(50)  NOT NULL,
    "PASSWORD" VARCHAR(500) NOT NULL,
    "ENABLED"  TINYINT      NOT NULL

二、实现步骤

2.1 nacos源码中引入达梦8数据库的驱动包

建议使用达梦数据库自带的驱动,达梦数据库安装目录下drivers/jdbc下的驱动，否则可能会出现驱动版本不兼容的问题 （读取超长CLOB，TEXT）

在naming模块和console模块的resources目录下新建lib目录，把DmJdbcDriver18.jar包拷贝进去，自行找一个合适的驱动jar包。

分别在naming模块和console模块的pom.xml下新增依赖项：

  <dependency>
            <groupId>com.dameng</groupId>
            <artifactId>DmJdbcDriver18</artifactId>
            <version>8.1.3.140</version>
        </dependency>

2.2 修改nacos源码

（1）.把下载的nacos-plugin-develop中的nacos-datasource-plugin-ext模块下的nacos-datasource-plugin-ext-base中的源码依次拷贝进入nacos-2.3.2中的datasource模块下，注意路径。如图所示：



（2）.把下载的nacos-plugin-develop中的nacos-datasource-plugin-ext模块下的nacos-dm-datasource-plugin-ext中的源码依次拷贝进入nacos-2.3.2中的datasource模块下，注意路径。

注意不要拷贝src/main/resources/META-INF/services/com.alibaba.nacos.plugin.datasource.mapper.Mapper这个文件，防止覆盖，等下我们要自己新增一些内容。



（3）.修改nacos-2.3.2\plugin\datasource\src\main\resources\META-INF\services\com.alibaba.nacos.plugin.datasource.mapper.Mapper的这个文件，在最下面新增如下：

com.alibaba.nacos.plugin.datasource.impl.dm.ConfigInfoAggrMapperByDaMeng
com.alibaba.nacos.plugin.datasource.impl.dm.ConfigInfoBetaMapperByDaMeng
com.alibaba.nacos.plugin.datasource.impl.dm.ConfigInfoMapperByDaMeng
com.alibaba.nacos.plugin.datasource.impl.dm.ConfigInfoTagMapperByDaMeng
com.alibaba.nacos.plugin.datasource.impl.dm.ConfigTagsRelationMapperByDaMeng
com.alibaba.nacos.plugin.datasource.impl.dm.HistoryConfigInfoMapperByDaMeng

2.3 编译打包

在终端打开nacos-2.3.2，运行如下命令：

mvn -Prelease-nacos -Dmaven.test.skip=true -Dpmd.skip=true -Drat.skip=true -Dcheckstyle.skip=true clean install -U

如果构建成功，则在distribution模块下有生成的nacos包：

三、运行验证

把nacos-server-2.3.2.zip取出解压缩，修改conf目录下的application.properties配置文件：

### Default web context path:
server.servlet.contextPath=/nacos
### Include message field
server.error.include-message=ALWAYS
### Default web server port:
server.port=8848

### Count of DB:
db.num=1

### Connect URL of DB:
spring.sql.init.platform=dm
db.url.0=jdbc:dm://10.10.10.104:5236?schema=NACOS
db.user.0=SYSDBA
db.password.0=SYSDBA001
db.pool.config.driverClassName=dm.jdbc.driver.DmDriver

### Connection pool configuration: hikariCP
db.pool.config.connectionTimeout=30000
db.pool.config.validationTimeout=10000
db.pool.config.maximumPoolSize=20
db.pool.config.minimumIdle=2

### the maximum retry times for push
nacos.config.push.maxRetryTime=50

#***********Metrics for tomcat **************************#
server.tomcat.mbeanregistry.enabled=true

#***********Expose prometheus and health **************************#
#management.endpoints.web.exposure.include=prometheus,health

### Metrics for elastic search
management.metrics.export.elastic.enabled=false
#management.metrics.export.elastic.host=http://localhost:9200

### Metrics for influx
management.metrics.export.influx.enabled=false

#*************** Access Log Related Configurations ***************#
### If turn on the access log:
server.tomcat.accesslog.enabled=true

### file name pattern, one file per hour
server.tomcat.accesslog.rotate=true
server.tomcat.accesslog.file-date-format=.yyyy-MM-dd-HH
### The access log pattern:
server.tomcat.accesslog.pattern=%h %l %u %t "%r" %s %b %D %{User-Agent}i %{Request-Source}i

### The directory of access log:
server.tomcat.basedir=file:.

#*************** Access Control Related Configurations ***************#
### If enable spring security, this option is deprecated in 1.2.0:
#spring.security.enabled=false

### The ignore urls of auth
nacos.security.ignore.urls=/,/error,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-ui/public/**,/v1/auth/**,/v1/console/health/**,/actuator/**,/v1/console/server/**

### The auth system to use, currently only 'nacos' and 'ldap' is supported:
nacos.core.auth.system.type=nacos

### If turn on auth system:
nacos.core.auth.enabled=true

### Turn on/off caching of auth information. By turning on this switch, the update of auth information would have a 15 seconds delay.
nacos.core.auth.caching.enabled=true

### Since 1.4.1, Turn on/off white auth for user-agent: nacos-server, only for upgrade from old version.
nacos.core.auth.enable.userAgentAuthWhite=false

### Since 1.4.1, worked when nacos.core.auth.enabled=true and nacos.core.auth.enable.userAgentAuthWhite=false.
### The two properties is the white list for auth and used by identity the request from other server.
nacos.core.auth.server.identity.key=nacos
nacos.core.auth.server.identity.value=nacos

### worked when nacos.core.auth.system.type=nacos
### The token expiration in seconds:
nacos.core.auth.plugin.nacos.token.cache.enable=false
nacos.core.auth.plugin.nacos.token.expire.seconds=18000
### The default token (Base64 String):
nacos.core.auth.plugin.nacos.token.secret.key=SecretKey012345678901234567890123456789012345678901234567890123456789

nacos.istio.mcp.server.enabled=false

具体的配置规则参考官网：https://nacos.io/docs/latest/concepts/

在bin目录下运行cmd，输入startup.cmd -m standalone



访问localhost:8848/nacos



新增一些配置文件，在达梦数据库的NACOS.CONFIG——INFO表中看到如下：



也可以创建一个简单的spring cloud的demo来实验注册中心和配置中心：





如上图，springcloud-demo已经成功注册到nacos，并且能读出nacos中的配置文件的值，说明此达梦数据库版nacos可用。

至此nacos适配达梦数据库成功！

四、福利（直接看这里可以拿到已经做好的成品）
