1.request.getCharacterEncoding("utf-8");

2.new String(username.getBytes("iso-8859-1","utf-8"))

在server.xml中找到Connector標籤 添加一個屬性useBodyEncodingForUrl="true"或者URIEncoding="utf-8";

4.數據庫與表設置

5.響應亂碼

response.setContextType("text/html");

response.setCharacterEncoding("utf-8");

6.連接字符串編碼設置

jdbc:mysql://localhost:3306/album?characterEncoding=utf-8
