JDBC连接oracle数据库

引入ojdbc14.jar(或ojdbc.jar，视数据库版本定，这里是oracle11g)包

代码如下

import java.sql.DriverManager;


import java.sql.Connection;


import java.sql.Statement;


import java.sql.ResultSet;


import java.sql.SQLException;


public class LinkData {
	public static void main(String args[]){
	
	try{
		
		Class.forName("oracle.jdbc.driver.OracleDriver");
		
		
		String url="jdbc:oracle:thin:@192.168.1.121:1521:test";
		
		Connection conn= DriverManager.getConnection(url,"test","test");
		
		Statement stmt= conn.createStatement();
		ResultSet rs =stmt.executeQuery("select * from userinfo");
		
		while(rs.next()){
			
			System.out.println("name:"+rs.getString(2));
			
		}
		
		rs.close();
		stmt.close();
		conn.close();
		
		
	}catch(ClassNotFoundException e){
		e.printStackTrace();
		
		System.out.println("Its a Jdbc Connection!");
		
	}catch (SQLException e){
		
		e.printStackTrace();
	}
	
	}


}
