JAVA连接ORACLE数据库

当然别忘了ORACLE的数据库驱动程序
import java.sql.*;
public class DBConn
{
  public static Connection getConnection()
  { //Oracle数据库连接
    String ClassforName = "oracle.jdbc.driver.OracleDriver";
    String SERVandDB = 
      "jdbc:oracle:thin:@10.6.0.120:1521:db"; //"DataSource,DataName不能用
    String USER = "hr"; //用户名
    String PWD = "hr"; //密码
    Connection con = null;
    try
    {
      Class.forName(ClassforName).newInstance();
      con = DriverManager.getConnection(SERVandDB, USER, PWD);
      con.setAutoCommit(false);
    }
    catch (Exception e)
    {
      e.printStackTrace();
    }    
    return con;
  }
}
