中文乱码

1、js=>java

js:var logName=encodeURI(logName);//因中文先encodeURI

java:URLDecoder.decode(ObjectUtils.toString(this.getParameter("logName")),"UTF-8");//因中文先encodeURI后URLDecoder



2、java=>jsp

java: resName=URLEncoder.encode(logName,"UTF-8");//因中文先URLEncoder.encode后URLDecoder.decode
this.setAttribute("loginName",resName);

jsp  <input type="text" value="<%=URLDecoder.decode(ObjectUtils.toString(request.getAttribute("logName")),"UTF-8") %>"/>
