Answer 2

这个问题已经解决了,但又出现了新的问题当我连接的时候报
java.sql.SQLException: Io 异常: Connection refused(DESCRIPTION=(TMP=)(VSNNUM=169869568)(ERR=12505)(ERROR_STACK=(ERROR=(CODE=12505)(EMFI=4))))

我的连接语句是
 Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
           return DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:ORCL","scott","tiger");
