SqlServer、Oracle、MySQL的连接,除了地址和驱动包不同,其他都一样的。

 1     public String urlString="jdbc:sqlserver://localhost:1433;databaseName=crebas;";
 2         //"jdbc:mysql://localhost:3306/crebas?autoReconnect=true&useUnicode=true&characterEncoding=utf8"
 3         //"jdbc:oracle:thin:@localhost:1521:ORCL"
 4     public String nameString="sa";
 5     public String password="123";
 6     public void test()
 7     {
 8         String driver = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
 9             //"com.mysql.jdbc.Driver"
10             //"oracle.jdbc.driver.OracleDriver"
11         try
12         {
13             Class.forName(driver);
14             Connection conn = DriverManager.getConnection(urlString, nameString, password);
15             PreparedStatement pstmt = conn.prepareStatement("Select * from T_Admin");
16             ResultSet rs = pstmt.executeQuery();
17             rs.next();
18             System.out.println(rs.getString(1));
19             System.out.println(rs.getString(2));
20             System.out.println(rs.getString(3));
21         } catch (Exception e)
22         {
23             e.printStackTrace();
24         }
25     }

最基础的连接方式,好久之前整理的了,备忘一下。
