Java程序连接各种数据库的driver和url形式

1.Oracle数据库

Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
String url = "jdbc:oracle:thin:@localhost:1521:orcle";
String user = "test";
String password = "test";
Connection conn = DriverManager.getConnection(url, user, password);

 2.DB2数据库

Class.forName("com.ibm.db2.jdbc.app.DB2Driver").newInstance();
String url = "jdbc:db2://localhost:5000/testDB";
String user = "admin";
String password = "test";
Connection conn = DriverManager.getConnection(url, user, password);

 3.SQL Server数据库

Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
String url = "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=testDB";
String user = "sa";

Connection conn = DriverManager.getConnection(url, user, password);

4. Sybase数据库

Class.forName("com.sybase.jdbc.SybDriver").newInstance();
String url = "jdbc:sybase:Tds:localhost:5007/testDB";
Properties sysProps = System.getProperties();
sysProps.put("user", "userid");
sysProps.put("password", "user_password");
Connection conn = DriverManager.getConnection(url, sysProps);

Connection conn = DriverManager.getConnection(url);

 6.MySQL数据库

Class.forName("org.gjt.mm.mysql.Driver").newInstance();
String url = "jdbc:mysql://localhost/testDB?user=testuser&password=testpassword&useUnicode=true&characterEncoding=GB2312";
Connection conn = DriverManager.getConnection(url);

 7.PostgreSQL数据库
