你好 ， 

项目建好后运行会出现404错误，

并且console会显示以下信息 。

信息: Server startup in 2649 ms

select * from tb_class

select * from tb_board where board_classID=?

select count(bbs_id) from tb_bbs where bbs_boardID=?

SELECT COUNT(bbs_id) AS num FROM tb_bbs WHERE (bbs_boardID = ?) AND (bbs_id NOT IN (SELECT bbsAnswer_rootID FROM tb_bbsAnswer))

select count(bbs_id) from tb_bbs where bbs_boardID=? and bbs_isGood='1'

请问这个问题怎么解决？
