ORA-28009：connection as SYS should be as SYSDBA OR SYSOPER解决方法

错误提示里的大致意思：作为sys的连接应该是SySDBA或Sysopor
所以,我们在登录的时候，可以试一下：sys as sysdba 

    //数据库连接地址
    private static String url="jdbc:oracle:thin:@192.168.1.180:1521:orcl";
    //用户名
    private static String username= "sys as sysdba";
    //密码
    private static String password ="admindljjk";
    //驱动名称
    private static String jdbcName = "oracle.jdbc.OracleDriver";
