sql读取加密后的配置文件

一，写一个DB连接工具类

package com.hooypay.tool;

import java.io.IOException;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.Properties;

import org.apache.commons.codec.binary.Base64;
