Java数据库连接接口（JDBC）是Java里定义的一套用于数据库连接和操作的API的集合。由不同的数据库厂商提供这套接口的实现类，对于java程序员来说，程序员不需要关心数据库的底层的实现，统一的调用JDBC里的抽象出来的API来完成数据库的访问功能，在Data access的功能和接口定义中，java是在别的语言里实现的比较理想的， 作为程序员需要的是，知道每个数据库的不同的JDBC的实现，也就是driver，以及对数据库的URL的描述，其他的一切也就是通过统一的调用来实现了，本文章收集了主要的数据库厂商提供的driver和url，以便大家方便的对各种数据库进行连接的操作。


JDBC里统一的使用方法
Class.for(jdbcDriverName);
Connection conn= DriverManager.getConnection(url,user,password);
这里的接口是统一的，不同的是每种数据库提供的jdbcDriver和Url不同

我们一起来看看吧

MySQL?

Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://host:port/database","user","password");

Oracle数据库（thin模式）

Class.forName("oracle.jdbc.driver.OracleDriver");
Connection con = DriverManager.getConnection("jdbc:oracle:thin:@host:port:databse","user","password");

Timesten数据库（thin模式）

Class.forName("com.timesten.jdbc.TimesTenDriver");
Connection con = DriverManager.getConnection("jdbc:timesten:client:dsn=dsnname")

Microsoft SQL Server?
Class.forName("net.sourceforge.jtds.jdbc.Driver ");
Connection con = DriverManager.getConnection("jdbc:jtds:sqlserver://host:port/database","user","password");
or
Connection con = DriverManager.getConnection("jdbc:jtds:sybase://host:port/database","user","password");

DB2?
Class.forName("com.ibm.db2.jdbc.app.DB2Driver ");
Connection conn= DriverManager.getConnection("jdbc:db2://localhost:5000/sample",user,password);

Connection con = DriverManager.getConnection("jdbc:hsqldb:hsql://localhost:port/mydb","user","password");

Derby?
这个少有人听说吧，cloudscape 应该听说过吧，该项目由此衍生
Class.forName("org.apache.derby.jdbc.ClientDriver");
Connection con = DriverManager.getConnection("jdbc:derby://host:port//mydb","user","password");

Class.forName("org.apache.derby.jdbc.EmbeddedDriver");
Connection conn = DriverManager.getConnection("jdbc:derby:mynewDB", p);

cloudscape?
Class.forName("com.cloudscape.core.JDBCDriver");
Connection conn = DriverManager.getConnection("jdbc:cloudscape:<DB>");

Class.forName("com.cloudscape.rmiJdbc.RJDriver");
Connection conn = DriverManager.getConnection("jdbc:rmi://<HOST>:<PORT>/jdbc:cloudscape:<DB>", user, passoword);

Postgresql?
Class.forName("org.postgresql.Driver");
Connection con=DriverManager.getConnection("jdbc:postgresql://host:port/database","user","password");
