json格式数据导入到mysql

JDBCUTIL

可能用到的依赖：
 
            c3p0
            c3p0
            0.9.1.2
        


代码：
import java.sql.Connection;
import java.sql.SQLException;


import org.apache.commons.dbutils.QueryRunner;
import com.mchange.v2.c3p0.ComboPooledDataSource;

/**
 * 1. 获取数据源
 * 2. 获取连接对象
 * 3. 返回dbutils的QueryRunner对象
 */
public class JDBCUtil {
	private static ComboPooledDataSource dataSource = null;
	static {
		dataSource = new ComboPooledDataSource();
	}
	/**
	 * 1.获取数据库连接对象 （事务），这个连接对象需要手动释放
	 * @return
	 */
	public static Connection getConnection() {
		try {
			return dataSource.getConnection();
		} catch (SQLException e) {
			e.printStackTrace();
		}
		return null;
	}
	/**
	 * 2.获取dbutils的QueryRunner对象（非事务），资源会自动释放
	 * @return 
	 */
	public static QueryRunner getQueryRunner() {
		return new QueryRunner(dataSource);
	}
	
}
