struts 文件上传 乱码
action 代码:
public void savemovieinfo(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) { // TODO Auto-generated method stub MovieInfoForm mif = (MovieInfoForm)form; // Check that we have a file upload request try { FormFile file = mif.getFile(); InputStream moviefile_ = file.getInputStream(); String fileName_ = file.getFileName(); String intro = mif.getIntro(); FtpClientCommonNetImpl client_ = new FtpClientCommonNetImpl(); client_.setIJTH(jth_); Properties config_ = new Properties(); config_.setProperty("server", sysConfigForm.getFtp_movie_ip()); config_.setProperty("username", sysConfigForm.getFtp_movie_username()); config_.setProperty("password", sysConfigForm.getFtp_movie_psd()); client_.setConfig(config_); client_.upload(moviefile_, movienamesys, true); } catch (FileUploadException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } }
FtpClientCommonNetImpl具体操作类代码见上一篇《网页控件 上传 文件》
利用strtus进行文件上传与通过servlet进行文件上传的区别同样在于获取客户端文件的方式,由于strtus对页面的Form进行了封装,所以我们只能通过struts的ActionForm来获取文件流。
servlet中得到文件流是通过fileupload 包的FileItem:
List /* FileItem */ items = upload.parseRequest(request); FileItem item = (FileItem) iter.next(); String fileName = item.getName(); InputStream localIn = new FileInputStream(fileName);
用这种方式上传文件时,中文文件名称是没有问题的,要将文件名称进行转码,new String(paravalue.getBytes("GBK"),"ISO8859-1") 就不会有问题。
而通过struts来上传文件时用到的是FormFile类,
MovieInfoForm mif = (MovieInfoForm)form; // Check that we have a file upload request FormFile file = mif.getFile(); String intro = mif.getIntro(); String fileName_ = file.getFileName(); InputStream localIn_ = file.getInputStream();
但用file.getFileName()方法得到的文件名称是乱码,(页面编码是”UTF-8”),跟踪调试发现从struts的ActionForm 中取得的intro转一下码是正常的( new String(paravalue.getBytes("GBK"),"ISO8859-1") ),所以可能是struts封装的问题,google一下:http://hi.baidu.com/yds_amber/blog/item/4cdb0601451a8c05738da58f.html
所以这里必须用controller来处理,但spring配置文件里已经配置了 org.springframework.web.struts.DelegatingRequestProcessor
<controller> <set-property property="processorClass" value="org.springframework.web.struts.DelegatingRequestProcessor"/> </controller>
不知道这里能不能配置多个property属性,自己试了试没成功,所以这里只能配置成EncodingProcessor
<controller> <!-- set-property property="processorClass" value="org.springframework.web.struts.DelegatingRequestProcessor"/--> <set-property property="processorClass" value="com.business.admin.processor.EncodingProcessor"/> </controller>
EncodingProcessor类:
public class EncodingProcessor extends RequestProcessor{ public void process(HttpServletRequest request,HttpServletResponse response) throws IOException,ServletException{ String encoding="UTF-8"; request.setCharacterEncoding(encoding); response.setContentType("text/html;charset=UTF-8"); super.process(request, response); } }
但这样去掉DelegatingRequestProcessor配置就不能让spring来代理处理请求了,查看DelegatingRequestProcessor 源代码:
public class org.springframework.web.struts.DelegatingRequestProcessor extends org.apache.struts.action.RequestProcessor {
这个类已经继承了struts的RequestProcess类,所以修改一下以上代码,让EncodingProcessor 继承 DelegatingRequestProcessor就好了:
public class EncodingProcessor extends DelegatingRequestProcessor{ public void process(HttpServletRequest request,HttpServletResponse response) throws IOException,ServletException{ String encoding="UTF-8"; request.setCharacterEncoding(encoding); response.setContentType("text/html;charset=UTF-8"); super.process(request, response); } }
重启后,发现从request里 String fileName_ = file.getFileName(); 得到的值不用转码也是正常的。但上传中文文件名时候还是报错:
java.lang.Exception: java.lang.Exception: 文件上传失败! at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.struts.actions.DispatchAction.dispatchMethod(DispatchAction.java:269) at org.apache.struts.actions.DispatchAction.execute(DispatchAction.java:170) at org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:425) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:228) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1913) at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:462) at javax.servlet.http.HttpServlet.service(HttpServlet.java:710) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:263) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:584) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Thread.java:619) Caused by: java.lang.Exception: 文件上传失败! at com.util.ftp.FtpClientCommonNetImpl.upload(FtpClientCommonNetImpl.java:116) ... 30 more
这个问题折腾了两天,最后发现实页面编码设置和EncodingProcessor 里的设置不一样,将页面里的编码也设置成 UTF-8 就好了
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
后来又不知道动了哪根筋,只要上传中文名称的文件就还是报上面的错,debug里看从ActionForm 里取到的信息都是正常的中文字符。于是在ftp类里加了
FTPClientConfig conf = new FTPClientConfig(FTPClientConfig.SYST_NT); conf.setServerLanguageCode("zh"); ftp.setControlEncoding("UTF-8");
就可以上传客户端的中文字符的文件了,但是上传时成功后,到ftp服务器上的文件都成乱码了。于是怀疑conf.setServerLanguageCode("zh");没起作用,查看源代码:
