测试的电脑已经装好Oracle客户端,而且用SQLplus可以连接上。
/*
* This sample shows how to list all the names from the EMP table
*
* It uses the JDBC THIN driver. See the same program in the
* oci8 samples directory to see how to use the other drivers.
*/
// You need to import the java.sql package to use JDBC
import java.sql.*;
class Test
{
public static void main (String args [])
throws SQLException
{
// Load the Oracle JDBC driver
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
/* try{
Class.forName("oracle.jdbc.driver.OracleDriver");
}catch(Exception e){
System.out.println("No Driver!");
}
*/
// Connect to the database
// You must put a database name after the @ sign in the connection URL.
// You can use either the fully specified SQL*net syntax or a short cut
// syntax as <host>:<port>:<sid>. The example uses the short cut syntax.
String url = "jdbc:oracle:thin:@172.28.31.85:1521:YIKATONG";
String userName = "scott";
String password = "tiger";
if (args.length > 0) url = args[0];
if (args.length > 1) userName = args[1];
if (args.length > 2) password = args[2];
System.out.println(url);
System.out.println(userName);
System.out.println(password);
Connection conn =
DriverManager.getConnection (url, userName, password);
// Create a Statement
Statement stmt = conn.createStatement ();
// Select the ENAME column from the EMP table
ResultSet rset = stmt.executeQuery ("select * from Test");
// Iterate through the result and print the employee names
while (rset.next ())
System.out.println (rset.getString (1));
}
}

Java与Oracle的两种连接方式
src=http://pagead2.googlesyndication.com/pagead/show_ads.js>(作者:huihoo)
第一种方式:通过数据库本身的JDBC Driver连接到数据库
Classs.forName("oracle.jdbc.driver.OracleDriver");
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@192.168.1.33:1521:huihoo","scott","tiger");
第二种方式:通过JDBC-ODBC桥连接到数据库
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection conn = DriverManager.getConnection("jdbc:odbc:192.168.1.33","scott","tiger");
192.168.1.33为数据源
完整的用户登录
Properties props = new Properties();
props.put("user", "scott");
props.put("password", "tiger");
Driver myDriver = (Driver) Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
conn = myDriver.connect("jdbc:oracle:thin:@192.168.1.33:1521:huihoo", props);
conn.close();
System.out.println("成功登录.");
System.out.println("欢迎您 "+props.getProperty("user")+"!");
