KingbaseES数据库配置Hikari数据源

发布时间 2023-06-08 12:19:16作者: nwwhile

 

Hikari是一个高性能的数据库连接池，它是Spring Boot 2.x中的默认数据源。

一、下载驱动

打开下面网址：选择对应平台的jdbc驱动程序。

人大金仓-成为世界卓越的数据库产品与服务提供商 (kingbase.com.cn)

这里以x86平台为例：

下载完成后目录里面包含以下文件：根据项目的JDK版本选择对应的驱动

--kingbase8-8.6.0.jar>= jdk 1.8
kingbase8-8.6.0.jar    
--kingbase8-8.6.0.jar = jdk 1.6
kingbase8-8.6.0.jre6.jar
--kingbase8-8.6.0.jar = jdk 1.7
kingbase8-8.6.0.jre7.jar
--kingbase8-8.6.0.jar>= jdk 1.8
postgresql-42.2.9.jar
--kingbase8-8.6.0.jar = jdk 1.6
postgresql-42.2.9.jre6.jar
--kingbase8-8.6.0.jar = jdk 1.7
postgresql-42.2.9.jre7.jar

二、上传驱动jar包到maven仓库

以本地仓库为例：

--执行命令安装驱动到本地仓库
mvn install:install-file -Dfile=C:\DbTools\Interface\kingbase8-8.6.0.jar -DgroupId=com.kingbase8 -DartifactId=kingbase8 -Dversion=8.6.0 -Dpackaging=jar

安装过程：

D:\JAVA\jdk1.8.0_333\bin\java.exe -Dmaven.multiModuleProjectDirectory=C:\Users\realGuob\Desktop\Work\code\Hikari -Djansi.passthrough=true "-Dmaven.home=C:\Program Files\JetBrains\IntelliJ IDEA 2022.3.3\plugins\maven\lib\maven3" "-Dclassworlds.conf=C:\Program Files\JetBrains\IntelliJ IDEA 2022.3.3\plugins\maven\lib\maven3\bin\m2.conf" "-Dmaven.ext.class.path=C:\Program Files\JetBrains\IntelliJ IDEA 2022.3.3\plugins\maven\lib\maven-event-listener.jar" "-javaagent:C:\Program Files\JetBrains\IntelliJ IDEA 2022.3.3\lib\idea_rt.jar=58778:C:\Program Files\JetBrains\IntelliJ IDEA 2022.3.3\bin" -Dfile.encoding=UTF-8 -classpath "C:\Program Files\JetBrains\IntelliJ IDEA 2022.3.3\plugins\maven\lib\maven3\boot\plexus-classworlds-2.6.0.jar;C:\Program Files\JetBrains\IntelliJ IDEA 2022.3.3\plugins\maven\lib\maven3\boot\plexus-classworlds.license" org.codehaus.classworlds.Launcher -Didea.version=2022.3.3 install:install-file -Dfile=C:\DbTools\Interface\kingbase8-8.6.0.jar -DgroupId=com.kingbase8 -DartifactId=kingbase8 -Dversion=8.6.0 -Dpackaging=jar

没有报错说明已成功安装，安装成功后建议更新下maven索引。

三、配置pom.xml

添加如下依赖：

<dependencies>
        <dependency>
            <groupId>com.zaxxer</groupId>
            <artifactId>HikariCP</artifactId>
            <version>4.0.3</version>
        </dependency>
        <dependency>
            <groupId>com.kingbase8</groupId>
            <artifactId>kingbase8</artifactId>
            <version>8.6.0</version>
        </dependency>
</dependencies>

添加完成后刷新或者使用maven重新加载下项目。

四、Hikari数据源测试

1.创建HikariConfig对象设置数据库的相关属性：用户名、密码、端口号、数据库名称、数据源对象等

import com.zaxxer.hikari.HikariConfig;
import com.zaxxer.hikari.HikariDataSource;
​
public class DBUtil {
    static final HikariDataSource DS;
    static {
        HikariConfig config = new HikariConfig();
        config.setAutoCommit(true);
        config.setDataSourceClassName("com.kingbase8.ds.KBSimpleDataSource");
        config.setUsername("system");
        config.setPassword("system");
        config.addDataSourceProperty("serverName", "192.168.10.43");
        config.addDataSourceProperty("portNumber", 5432);
        config.addDataSourceProperty("databaseName", "test");
        DS = new HikariDataSource(config);
    }
    public static void close() {
        DS.close();
    }
}

2.测试创建的数据源对象：

import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
​
public class Test {
    public static void main(String[] args) {
        try (Connection conn = DBUtil.DS.getConnection();
             Statement stmt = conn.createStatement();
             ResultSet rs = stmt.executeQuery("select * from tb limit 10")) {
            while (rs.next()) {
                System.out.println(rs.getLong("id") + "\t" + rs.getDate("pdate") + "\t" + rs.getString("info"));
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}

运行测试用例结果输出：
