问题描述：

　　下面是有关连接SqlServer2008R2和MySql数据库的封装类

 package com.test;

 import java.sql.Connection;
 import java.sql.DriverManager;

 public class DataBaseConn {

     private String databaseName = "";//数据名称
     private String useName = "";//用户登入名
     private String password ="";//登入密码

         this.password = "000000";
     }

     public DataBaseConn(String databaseName, String useName, String password){
         this.databaseName = databaseName;
         this.useName = useName;

     }

     public Connection con = null;

     private String MYSQLDRIVER = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
     private String MYSQLURL = "jdbc:mysql://localhost:3306/" + databaseName + "?use" + useName + "&password" + password + "&useUnicode=true&characterEncoding=gb2312";
     //SQLsServer驱动

     public void createMysqlConn(){
         con = null;
         try{
             Class.forName(MYSQLDRIVER).newInstance();
             con = DriverManager.getConnection(MYSQLURL);
         }catch(Exception e){
             e.printStackTrace();
         }
     }
     //SQLsServer驱动
     public void createMssqlConn(){

             con = DriverManager.getConnection(MSSQLURL, "sa", "000000");
         }catch(Exception e){
             e.printStackTrace();
         }
     }

     public Connection getMysqlConn(){
         createMysqlConn();
         return con;
     }

     public Connection getMssqlConn(){
         createMssqlConn();
         return con;
     }

     public void closeCon(){
         if(con != null){
             try {
                 con.close();
                 con = null;
             } catch (Exception e) {
                 // TODO Auto-generated catch block
                 e.printStackTrace();
             }
         }
     }
