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();
}

}

}
