主公不搬砖2026-01-10 14:50

一、Nacos源码地址

地址：nacos-v2.5.2

二、代码适配

1、引入kingbase jdbc包

XML 复制代码 
# 引入 kingbase jdbc jar
/nacos/pom.xml
<dependencyManagement>
    <dependencies>
        ...

        <dependency>
            <groupId>com.kingbase</groupId>
            <artifactId>kingbase8</artifactId>
            <version>8.6.0</version>
        </dependency>

        ...

    </dependencies>
</dependencyManagement

# /nacos/persistence/pom.xml
<dependencies>
    ...

    <dependency>
        <groupId>com.kingbase</groupId>
        <artifactId>kingbase8</artifactId>
    </dependency>
    ...

</dependencies>

2、代码

1）ExternalDataSourceServiceImpl.java（nacos/persistence）

java 复制代码 
// 添加代码
if (Objects.isNull(jt.getDataSource())) {
    jt.setDataSource(dataSourceList.get(0));
}
java 复制代码 
    @Override
    public void init() {
        queryTimeout = ConvertUtils.toInt(System.getProperty("QUERYTIMEOUT"), 3);
        jt = new JdbcTemplate();
        // Set the maximum number of records to prevent memory expansion
        jt.setMaxRows(50000);
        jt.setQueryTimeout(queryTimeout);
        
        testMasterJT = new JdbcTemplate();
        testMasterJT.setQueryTimeout(queryTimeout);
        
        testMasterWritableJT = new JdbcTemplate();
        // Prevent the login interface from being too long because the main library is not available
        testMasterWritableJT.setQueryTimeout(1);
        
        //  Database health check
        
        testJtList = new ArrayList<>();
        isHealthList = new ArrayList<>();
        
        tm = new DataSourceTransactionManager();
        tjt = new TransactionTemplate(tm);
        
        // Transaction timeout needs to be distinguished from ordinary operations.
        tjt.setTimeout(TRANSACTION_QUERY_TIMEOUT);
        
        dataSourceType = DatasourcePlatformUtil.getDatasourcePlatform(defaultDataSourceType);
        
        if (DatasourceConfiguration.isUseExternalDB()) {
            try {
                reload();
            } catch (IOException e) {
                LOGGER.error("[ExternalDataSourceService] datasource reload error", e);
                throw new RuntimeException(DB_LOAD_ERROR_MSG, e);
            }
            
            if (this.dataSourceList.size() > DB_MASTER_SELECT_THRESHOLD) {
                PersistenceExecutor.scheduleTask(new SelectMasterTask(), 10, 10, TimeUnit.SECONDS);
            }
            PersistenceExecutor.scheduleTask(new CheckDbHealthTask(), 10, 10, TimeUnit.SECONDS);
        }
        if (Objects.isNull(jt.getDataSource())) {
            jt.setDataSource(dataSourceList.get(0));
        }
    }

2）DataSourceConstant.java(nacos/plugin/datasource)

java 复制代码 
public class DataSourceConstant {
    public static final String MYSQL = "mysql";
    
    public static final String DERBY = "derby";
    // 添加kingbase类型
    public static final String KINGBASE = "kingbase";
}

3）com.alibaba.nacos.plugin.datasource.mapper.Mapper(nacos/plugin/datasource)

bash 复制代码

package com.alibaba.nacos.plugin.datasource.impl.kingbase;

import com.alibaba.nacos.plugin.datasource.constants.DataSourceConstant;
import com.alibaba.nacos.plugin.datasource.mapper.TenantInfoMapper;

/**
 * The abstract kingbase mapper contains CRUD methods.

public class TenantInfoMapperByKingbase extends AbstractMapperByKingbase implements TenantInfoMapper {

    @Override
    public String getDataSource() {
        return DataSourceConstant.KINGBASE;
    }

}

3.、编译 （产物在nacos/distribution/target目录下）

bash 复制代码 
mvn -Prelease-nacos -Dmaven.test.skip=true clean install -U

三、使用（nacos-2.5.2.zip）

1、默认数据库（derby）

bash 复制代码 
nacos/bin/startup.sh -m standalone

2、mysql数据库

bash 复制代码 
# application.properties
spring.datasource.platform=mysql
db.num=1
db.url.0=jdbc:mysql://localhost:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&serverTimezone=Asia/Shanghai
db.user.0=
db.password.0=
bash 复制代码 
nacos/bin/startup.sh -m standalone

3、kingbase数据库

bash 复制代码 
spring.datasource.platform=kingbase
db.num=1
db.url.0=jdbc:kingbase8://127.0.0.1:54321/test?&currentSchema=nacos&compatibleMode=mysql&ignoreCase=true&ENCODING=utf-8
db.user.0=
db.password.0=
db.pool.config.driverClassName=com.kingbase8.Driver
bash 复制代码 
nacos/bin/startup.sh -m standalone

四、容器化

1、Dockerfile

bash 复制代码 
FROM nacos/nacos-server:v2.5.2

COPY nacos-server.jar /home/nacos/target/nacos-server.jar
COPY application.properties /home/nacos/conf/application.properties

2、application.properties

bash 复制代码 
# spring
server.servlet.contextPath=${SERVER_SERVLET_CONTEXTPATH:/nacos}
server.contextPath=/nacos
server.port=${NACOS_APPLICATION_PORT:8848}
server.tomcat.accesslog.max-days=30
server.tomcat.accesslog.pattern=%h %l %u %t "%r" %s %b %D %{User-Agent}i %{Request-Source}i
server.tomcat.accesslog.enabled=${TOMCAT_ACCESSLOG_ENABLED:false}
server.error.include-message=ALWAYS

### The token expiration in seconds:

### The default token:
nacos.core.auth.plugin.nacos.token.secret.key=${NACOS_AUTH_TOKEN:}
### Turn on/off caching of auth information. By turning on this switch, the update of auth information would have a 15 seconds delay.

nacos.naming.distro.syncRetryDelay=5000
nacos.naming.data.warmup=true
nacos.console.ui.enabled=true
nacos.core.param.check.enabled=true

3、打镜像

bash 复制代码 
# nacos-server.jar、application.properties、Dockerfile在同一目录下
docker build -t nacos/nacos-server-v2.5.2-xc .

# 查看镜像
docker images

4、配置

bash 复制代码 
SPRING_DATASOURCE_PLATFORM=[derby|mysql|kingbase]
DB_SERVICE_URL=
DB_SERVICE_USER=
DB_SERVICE_PASSWORD=

kingbase 示例

bash 复制代码 
SPRING_DATASOURCE_PLATFORM=kingbase
DB_SERVICE_URL=jdbc:kingbase8://127.0.0.1:54321/nacos?&currentSchema=nacos&compatibleMode=mysql&ignoreCase=true&ENCODING=utf-8
