Question

我正在尝试执行以下程序，但我得到了 -

java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver

异常。请建议修复。我是java的新手。我基本上是想从DB的T_Profile表读取一个值并打印出来。

public static void main(String[] args) throws Exception
{
    String addr = "jdbc:oracle:thin:@hostName:1521:serviceName";
    String un = "username";
    String pw = "password";
    Connection con = null;
    try
    {
        Class.forName("oracle.jdbc.driver.OracleDriver");
        con = DriverManager.getConnection(addr,un,pw);
        Statement stat = con.createStatement();
        String query = "select * from schema.T_PROFILE where profile_id = 100292";
        ResultSet rs = stat.executeQuery(query);
        while(rs.next())
        {
            String Profile_id = rs.getString(1);
            System.out.println(Profile_id);
        }
    }
    catch(Exception e)
    {
    System.out.println(e);  
    }
}
