Nacos适配Kingbase数据库

Deryck_德瑞克2026-05-01 9:38

背景：

需要将nacos适配Kingbase数据库

1.下载nacos源码

2.源码修改

2.1 ExternalDataSourceProperties.java 修改
java 复制代码 
package com.alibaba.nacos.config.server.service.datasource;

public class ExternalDataSourceProperties {

    private static final String JDBC_DRIVER_NAME = "com.kingbase8.Driver";
    
    private static final String TEST_QUERY = "SELECT 1";
    
    private Integer num;
    
    private List<String> url = new ArrayList<>();
    
    private List<String> user = new ArrayList<>();
    
    private List<String> password = new ArrayList<>();
    
    public void setNum(Integer num) {
        this.num = num;
    }
    
    public void setUrl(List<String> url) {
        this.url = url;
    }
    
    public void setUser(List<String> user) {
        this.user = user;
    }
    
    public void setPassword(List<String> password) {
        this.password = password;
    }
    
    /**
     * Build serveral HikariDataSource.
     *
     * @param environment {@link Environment}
     * @param callback    Callback function when constructing data source
     * @return List of {@link HikariDataSource}
     */
    List<HikariDataSource> build(Environment environment, Callback<HikariDataSource> callback) {
        System.out.println("================== ExternalDataSourceProperties.build() START ==================");
        System.out.println("db.num: " + this.num);
        System.out.println("db.url: " + this.url);
        System.out.println("db.user: " + this.user);
        System.out.println("================== ExternalDataSourceProperties.build() END ==================");

        List<HikariDataSource> dataSources = new ArrayList<>();
        Binder.get(environment).bind("db", Bindable.ofInstance(this));
        Preconditions.checkArgument(Objects.nonNull(num), "db.num is null");
        Preconditions.checkArgument(CollectionUtils.isNotEmpty(user), "db.user or db.user.[index] is null");
        Preconditions.checkArgument(CollectionUtils.isNotEmpty(password), "db.password or db.password.[index] is null");
        for (int index = 0; index < num; index++) {
            int currentSize = index + 1;
            Preconditions.checkArgument(url.size() >= currentSize, "db.url.%s is null", index);
            DataSourcePoolProperties poolProperties = DataSourcePoolProperties.build(environment);
            poolProperties.setDriverClassName(JDBC_DRIVER_NAME);
            poolProperties.setJdbcUrl(url.get(index).trim());
            poolProperties.setUsername(getOrDefault(user, index, user.get(0)).trim());
            poolProperties.setPassword(getOrDefault(password, index, password.get(0)).trim());
            HikariDataSource ds = poolProperties.getDataSource();
            ds.setConnectionTestQuery(TEST_QUERY);
            dataSources.add(ds);
            callback.accept(ds);
        }
        Preconditions.checkArgument(CollectionUtils.isNotEmpty(dataSources), "no datasource available");
        return dataSources;
    }
    
    interface Callback<D> {
        
        /**
         * Perform custom logic.
         *
         * @param datasource dataSource.
         */
        void accept(D datasource);
    }
}
2.2 引入 kingbase8-8.6.0.jar 驱动
2.3 pom.xml (nacos-config)

2.4 打包
XML 复制代码 
mvn -Prelease-nacos -Dmaven.test.skip=true -Dcheckstyle.skip=true -Dpmd.skip=true clean install -U

3. 启动nacos

3.1 配置 plugin
3.2 修改 application.properties
XML 复制代码 
spring.datasource.platform=mysql
spring.sql.init.platform=mysql
db.num=1
db.url.0=jdbc:kingbase8://ip:port/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
db.user.0=xxx
db.password.0=yyy

注意：spring.sql.init.platform=mysql 一定要加，否则nacos会 use embedded storage

3.3 启动

导航到 F:\nacos\nacos-2.1.2\distribution\target\nacos-server-2.1.2\nacos\bin

XML 复制代码 
startup.cmd -m standalone
3.4 成功日志
XML 复制代码 
F:\nacos\nacos-2.1.2\distribution\target\nacos-server-2.1.2\nacos\bin>startup.cmd -m standalone
