JAVA中文乱码总汇

 

问题：页面链接后加中文参数，中文是乱码。

解决方案：修改Tomcat的配置文件。修改conf/server.xml 字符集

原先：
 <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8445" />
修改后：
 <Connector port="7001" protocol="HTTP/1.1"
               connectionTimeout="20000"   URIEncoding="UTF-8"
               redirectPort="8445" />

 下载的文件名还中文

action中:
response.reset();  
   //设置响应类型
   response.setContentType("application/octet-stream");  
   //设置响应的文件名称,并转换成中文编码
   String fileName=response.encodeURL(new String(returnName.getBytes(),"ISO8859_1"));
   response.addHeader("Content-Disposition",   "attachment;filename="+fileName); 

downfile.jsp 另外一种直接之间写在jsp中
  response.setHeader("content-type","text/html;charset=gb2312");  
response.setHeader("Content-disposition","attachment; filename="+URLEncoder.encode(sFile, "utf-8")); //注意此处必须用utf-8编码，否则乱码

js 提交action

js文件中:
  var paras;
  paras  = "cnname=" + encodeURI(encodeURI(cnname)); //提交中文时转码
  paras += "&curl=" + encodeURI(encodeURI(curl));

action中:
String cnname = request.getParameter("cnname");
   cnname = java.net.URLDecoder.decode(cnname, "utf-8");  //中文乱码解决

--------------------------------------------------------------------------------
js ajax 提交 action

jsp文件
var vuserName=($("#userName").val());
   vuserName = encodeURI(vuserName);   //中文乱码
  
   if(vuserName!=""){
    $("#ts").html("正在加载...");
    $.post("ajaxAutoCompleteAction.do",{userName:vuserName},function(m){
     $("#ts").html("<font color=#ff8800;><strong>提示：用鼠标或方向键选取</strong></font>"+unescape(m));
     $("#ts>a").bind("click",vst);
     $("#ts").css("display","block");
     //初始化全局变量
     a_i=-1;
    });
   }else{
    $("#ts").css("display","none");
   }

ajax action文件：
   String name = request.getParameter("userName");
   name = java.net.URLDecoder.decode(name, "utf-8"); //中文乱码

--------------------------------------------------------------------------------

jsp 提交jsp

<%
 response.setHeader("content-type","text/html;charset=gb2312");
 String swfFileName = UtilFuns.ConvertNull(request.getParameter("swfFileName"));
 if(swfFileName.compareTo("")==0){
  swfFileName = "doc/陕西省电力公司班组信息系统项目周报(20110104-20110107).swf";
 }
 swfFileName = java.net.URLDecoder.decode(swfFileName, "utf-8");  //中文乱码解决
%>

--------------------------------------------------------------------------------

submit提交到action, action重定向

urlPara = new String(urlPara.getBytes("gbk"), "ISO8859_1"); //必须转一次码，不然打开新窗口，url中文部分乱码
response.sendRedirect(reportUrl + "?" + urlPara);

--------------------------------------------------------------------------------
ajax提交到SaveAction

js文件中:
paras2  = "&rejectCS=" + encodeURI(rejectCS); //提交中文时转码

--------------------------------------------------------------------------------
ajax提交到action返回串, 在页面显示

js文件中:
paraString += "&" + list[i].name + "=" + encodeURI(encodeURI(list[i].value)); //提交中文时转码

action中:
   response.setContentType("text/html;charset=gbk"); //设定字符集，不然返回字符乱码
   response.setCharacterEncoding("gbk");
   PrintWriter out = response.getWriter();

   //列出本部门所有人员的周总结
   out.write(this.getDeptWeekSumUpList(cdBeginDate, request));
