中文用戶名在保存時(shí)亂碼……
=-=代碼基本和老師給的相同，只不過(guò)我在登陸的時(shí)候加了一個(gè)密碼的驗(yàn)證。登陸成功后，發(fā)現(xiàn)查看用戶信息時(shí)的中文用戶名是亂碼狀態(tài)。我覺(jué)得應(yīng)該是將用戶名保存進(jìn)cookie時(shí)出現(xiàn)了亂碼，但存入cookie的方法是老師說(shuō)的那種。主要代碼貼出，請(qǐng)指教
這是dologin.jsp的內(nèi)容

修改server.xml文檔，在Connector標(biāo)簽里面添加URIEncoding="utf-8"應(yīng)該能夠解決

跟你一樣，原來(lái)的樣例直接拷貝，結(jié)果上面這三行沒(méi)刪：
就造成一直亂碼，懷疑是javaBeans做處理時(shí)，更改了編碼。
猜想因?yàn)榍懊姹韱沃械膗sername password，正好被上面配置的javabean給自動(dòng)匹配上了。所以這個(gè)階段處理時(shí)，編碼發(fā)生了轉(zhuǎn)換。

=-=使用復(fù)制粘貼不斷進(jìn)行對(duì)比后，發(fā)現(xiàn)問(wèn)題竟然是出在
<jsp:useBean?id="loginUser"?class="com.po.Users"?scope="page"/>
<jsp:useBean?id="userDAO"?class="com.dao.UsersDAO"?scope="page"/>
<jsp:setProperty?name="loginUser"?property="*"/>
這段聲明中，若是把這段代碼刪去，編碼就沒(méi)有問(wèn)題。這是何等奇葩的現(xiàn)象，真心求解……
