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:
