There is a problem with the HikariCP configuration run time

this is the project architecture, which is a simple console test to connect to the mysql database

this is the configuration file

jdbcUrl = jdbc:mysql://localhost:3306/test?serverTimezone=GMT%2B8
user = root
password = 123456
dataSource.cachePrepStmts = true
dataSource.prepStmtCacheSize = 250
dataSource.prepStmtCacheSqlLimit = 2048
dataSource.useServerPrepStmts = true
dataSource.useLocalSessionState = true
dataSource.useLocalTransactionState=true
dataSource.rewriteBatchedStatements = true
dataSource.cacheResultSetMetadata = true
dataSource.cacheServerConfiguration = true
dataSource.elideSetAutoCommits = true
dataSource.maintainTimeStats = dataSource.maintainTimeStats

this is the code to test the connection
import java.sql.Connection;

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

import com.zaxxer.hikari.HikariConfig;
import com.zaxxer.hikari.HikariDataSource;

public class HikariPoolManager {

static Logger logger = LogManager.getLogger();
static HikariConfig config = new HikariConfig("/hurik.properties");
static HikariDataSource ds = new HikariDataSource(config);

/**
 * 
 * 
 * @return
 * @throws Exception
 */
public static Connection getConnection() throws Exception {

    Connection connection = null;
    try {
        connection = ds.getConnection();
    } catch (Exception e) {
        logger.error("!" + e);
        throw e;
    }
    return connection;
}

/**
 * 
 * 
 * @param connection
 * @throws Exception
 */
public static void freeConnection(Connection connection) throws Exception {
    if (connection != null) {
        try {
            connection.close();
        } catch (Exception e) {
            logger.error("!" + e.getMessage());
        }
    }
}

public static void main(String[] args) throws Exception {
    System.out.println(ds.getConnection());
}

}

Runtime error:

did not find a useful solution on the Internet, hope to get your help, or send a simple, complete and successful demo case
