java连接数据库URL

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";

String password = "test";

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);

5.Informix数据库

Class.forName("com.infoxmix.jdbc.IfxDriver").newInstance();

String url = "jdbc:infoxmix-sqli://localhost:1533/testDB:INFORMIXSERVER=myserver;user=testuser;password=testpassword";

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

Class.forName("org.postgresql.Driver").newInstance();

String url = "jdbc:postgresql://localhost/testDB";

String user = "myuser";

String password = "test";

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

实Hibernate本身是个独立的框架，它不需要任何web server或application server的支持。然而，大多数的Hibernate入门介绍都加入了很多非Hibernate的东西，比如: Tomcat, Eclipse, Log4J,Struts, XDoclet, 甚至JBoss。这容易让人产生Hibernate复杂难懂的误解，特别是打击了初学者的积极性。

在这篇文章将不涉及Eclipse, log4j, Struts, Tomcat, XDoclet，和JBoss。本文的目的是演示一下Hibernate的安装过程以及最基本的功能，从而给初学者一个低得不能再低的入门门槛。


下载文件

你需要Java SDK、 Hibernate包、Ant包、和JDBC Driver。

1、Hibernate包下载地址:
http://prdownloads.sourceforge.net/hibernate/?sort_by=date&sort=desc

2、Ant包下载地址:
http://apache.130th.net/ant/binaries/apache-ant-1.6.1-bin.zip

3、JDBC Driver要根据你用的database来定，一般database官方网站上都会有。Hibernate支持常用的database，比如 MySQL, Oracle, PostgreSQL, 和MS-SQL Server。这些数据库都有JDBC Driver:
