15、;Messages:6.在管理员部分出现：在管理员把发布公告的时候专项失败页面，经检查后，还是失败。 错误原因：我在数据库里没设置一个自增的值，又没在反向生产里面修改。public Notice(Stri ngnm essage,String n adm in, Date n time, Stri ng sxuehao,Stri ng nti tle) this . nmessage = nmessage;this . nadmin = nadmin;this . ntime= ntime;this . sxuehao = sxuehao;this . ntitle= ntitle;解决办法是
