亂碼問題解決：* POST請求亂碼 ：request.setCharacterEncoding("utf-8"); * GET請求亂碼解決方案一：修改tomcat/conf/server.xml <Connector port="80" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="utf-8"/>* 必須有修改tomcat服務(wù)器配置文件權(quán)限解決方案二：逆向編解碼username = URLEncoder.encode(username, "ISO8859-1");username = URLDecoder.decode(username, "utf-8");解決方案三：簡寫的方式（推薦使用）username = new String(username.getBytes("ISO-8859-1"),"utf-8");* request獲取中文數(shù)據(jù)亂碼（總結(jié)：）* post提交* 設(shè)置request緩沖區(qū)的編碼request.setCharacterEncoding("utf-8"); * get提交* String構(gòu)造方法username = new String(username.getBytes("ISO-8859-1"),"utf-8");
