Nacos适配人大金仓国产数据库

news2024/11/15 6:09:08

nacos版本2.2.0

人大金仓版本8.6.0

一、相关文件

Nacos官方文档-数据源插件icon-default.png?t=N6B9https://nacos.io/zh-cn/docs/v2/plugin/datasource-plugin.html


Nacos2.2.0源码icon-default.png?t=N6B9https://github.com/alibaba/nacos/archive/refs/tags/2.2.0.zip

 人大金仓驱动icon-default.png?t=N6B9https://download.csdn.net/download/qq_36802726/88165221

 二、Nacos源码修改

1.配置人大金仓依赖

下载源码与驱动。

源码打开后,如果项目依赖下载太慢可以换成阿里的:可以打开maven的setting.xml文件,把内容换成以下内容:

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
    <mirrors>
        <mirror>
            <id>alimaven</id>
            <name>aliyun maven</name>
            <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
            <mirrorOf>central</mirrorOf>
        </mirror>
    </mirrors>
</settings>

 引入人大金仓驱动,先用maven 安装kingbase8.8.6.0.jar:

//打开命令行,使用以下命令安装本地jar
mvn install:install-file -Dfile=D:\library\kingbase8.8.6.0.jar -DgroupId=com.kingbase -DartifactId=kingbase8 -Dversion=8.6.0 -Dpackaging=jar

引入依赖,打开项目父pom文件 nacos-all

 <!--人大金仓 -->
        <dependency>
            <groupId>com.kingbase</groupId>
            <artifactId>kingbase8</artifactId>
            <version>8.6.0</version>
        </dependency>

 2、源码修改

 2.1.找到DataSourceConstant.java,增加kingbase数据常量

 


public class DataSourceConstant {
    public static final String MYSQL = "mysql";
    
    public static final String DERBY = "derby";

    public static final String KINGBASE = "kingbase";
}

 2.2、新建人大金仓数据源插件

 2.2.1、ConfigInfoAggrMapperByKingbase

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

import com.alibaba.nacos.plugin.datasource.constants.DataSourceConstant;
import com.alibaba.nacos.plugin.datasource.impl.base.BaseConfigInfoAggrMapper;

/**

 *
 * @author zc
 **/

public class ConfigInfoAggrMapperByKingbase  extends BaseConfigInfoAggrMapper {
    
    @Override
    public String getDataSource() {
        return DataSourceConstant.KINGBASE;
    }
}

 

 2.2.2、ConfigInfoBetaMapperByKingbase.java
 2.2.3、ConfigInfoMapperByKingbase.java
 2.2.4、ConfigInfoTagMapperByKingbase.java
 2.2.5、ConfigInfoTagsRelationMapperByKingbase.java
 2.2.6、GroupCapacityMapperByKingbase.java
 2.2.7、HistoryConfigInfoMapperByKingbase.java
 2.2.8、TenantCapacityMapperByKingbase.java
 2.2.9、TenantInfoMapperByKingbase.java

2.3、plugin/datasource/src/main/resources/META-INF/services 下增加以下数据

com.alibaba.nacos.plugin.datasource.impl.kingbase.TenantInfoMapperByKingbase

 

 2.4、修改配置文件连接数据库

 

### kingbase:
spring.sql.init.platform=kingbase
db.num=1
db.url.0=jdbc:kingbase8://192.168.0.1:54321/nacos?currentSchema=nacos&allowEncodingChanges=true&clientEncoding=UTF8&zeroDateTimeBehavior=convertToNull&allowMultiQueries=true
db.user.0=nacos
db.password.0=nacos
db.pool.config.driverClassName=com.kingbase8.Driver

 需要注意url的第一个nacos代表数据库名,参数currentSchema后面是数据库的模式名。

2.5、手动增加数据源

不然后面启动项目会报错

Invocation of init method failed; nested exception is ErrCode:500, ErrMsg:Nacos Server did not start because dumpservice bean construction failure :
No DataSource set

在ExternalDataSourceServiceImpl 

找到方法public void init() 追加

  if(Objects.isNull(jt.getDataSource())){
            jt.setDataSource(dataSourceList.get(0));
        }

完整方法

    @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 (PropertyUtil.isUseExternalDB()) {
            try {
                reload();
            } catch (IOException e) {
                FATAL_LOG.error("[ExternalDataSourceService] datasource reload error", e);
                throw new RuntimeException(DB_LOAD_ERROR_MSG, e);
            }
            
            if (this.dataSourceList.size() > DB_MASTER_SELECT_THRESHOLD) {
                ConfigExecutor.scheduleConfigTask(new SelectMasterTask(), 10, 10, TimeUnit.SECONDS);
            }
            ConfigExecutor.scheduleConfigTask(new CheckDbHealthTask(), 10, 10, TimeUnit.SECONDS);
        }
        if(Objects.isNull(jt.getDataSource())){
            jt.setDataSource(dataSourceList.get(0));
        }
    }

 

2.6、配置调试

maven执行 mvn install

如果控制台显示

java: 程序包com.alibaba.nacos.consistency.entity不存在java: 程序包com.alibaba.nacos.consistency.entity不存在 

 可以执行

 然后刷新一下maven在执行 mvn install

成功后进行运行配置

-Dnacos.standalone=true 代表单例运行 

 这说明项目启动成功

INSERT INTO roles (username, role) VALUES ('nacos', 'ROLE_ADMIN');

三、 构建打包

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

或者

mvn -Prelease-nacos clean package install -Dmaven.test.skip=true

成功后在distribution的target下生成两个包

nacos-server-2.2.0.tar.gz 是linux环境的

nacos-server-2.2.0.zip 是windows环境的
