spring-jdbc5新特性，一个配置文件解决临时修改数据库的问题

import java.sql.SQLException;
import java.util.List;
import java.util.Map;

import javax.sql.DataSource;

import org.apache.commons.io.FilenameUtils;
import org.springframework.jdbc.core.JdbcTemplate;

import com.alibaba.fastjson.JSONArray;
import com.zaxxer.hikari.HikariDataSource;

public class UpdataGbrecUtil {

    public static void main(String[] args) {

        String path=Thread.currentThread().getContextClassLoader().getResource("hikariCP.properties").getPath();
        path=FilenameUtils.separatorsToUnix(path);
        System.setProperty("hikaricp.configurationFile", path);
        DataSource ds = new HikariDataSource();
        try {
            System.out.println(ds.getConnection());
            JdbcTemplate jdbc = new JdbcTemplate(ds);
            List<Map<String, Object>> data = jdbc.queryForList("select * from sheet1 ");
            JSONArray arr=(JSONArray) JSONArray.toJSON(data);
            System.out.println(arr.toString());
        } catch (SQLException e) {
            e.printStackTrace();
        }

    }
}
