‘jsp乱码总结’

1. request.setCharetEncoding(“utf-8”);
2. response.setCharerEncoding(“utf-8”);
3. response.setContextType(“text/html;charset=utf-8”);
4. 如果是request.getParameter(“参数名称”)获取中文乱码

String keyCodeStr=request.getParameter("keyCodeStr");

keyCodeStr= new String(keyCodeStr.getBytes("ISO8851-1"),"utf-8");
