连接oracle jdbc

我使用的是精简版的oracle。

1  导入oracle驱动包

oracle下路径

D:oracleapporacleproduct11.2.0serverjdbclibojdbc6.jar

2  查看listenerduankouhao

D:oracleapporacleproduct11.2.0server etworkADMINlistener.ora

3  代码

Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:XE", "yu", "123");

精简版默认名为XE。

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class jdbc {

    /**
     * @param args
     * @throws SQLException 
     */
    public static void main(String[] args) throws SQLException {
        try{
            Class.forName("oracle.jdbc.driver.OracleDriver");  
            //new oracle.jdbc.driver.OracleDriver();  
            Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:XE", "yu", "123");
            if(conn != null){
                System.out.println("数据库连接成功!");
                conn.close();
               }else{
                    System.out.println("数据库连接失败!");
               }
            }catch(ClassNotFoundException e){
               e.printStackTrace();
               }     
        }
   }
