import org.springframework.stereotype.Component;
import ru.yandex.clickhouse.ClickHouseConnection;
import ru.yandex.clickhouse.ClickHouseDataSource;
import ru.yandex.clickhouse.settings.ClickHouseProperties;

import java.sql.*;
import java.util.*;

@Component
public class ClickHouseUtil {

    private static String clickhouseAddress;

    private static String clickhouseUsername;

    }

    @Value("${clickhouse.username}")
    public void setClickhouseUsername(String username) {
        ClickHouseUtil.clickhouseUsername = username;
    }

    @Value("${clickhouse.password}")

        ClickHouseDataSource clickHouseDataSource = new ClickHouseDataSource(clickhouseAddress, properties);
        try {

            return conn;
        } catch (SQLException e) {
            e.printStackTrace();
        }

        return null;
    }


}

测试：

 @Test
    public void creatTable() {


        try {
            Connection connection = ClickHouseUtil.getConn();
            Statement statement = connection.createStatement();
            statement.executeQuery("create table default.example(name String, age UInt8) Engine=Log");
        } catch (SQLException e) {
            e.printStackTrace();
        }

    }
