[align=center]Struts文件上传[/align]
1. 页面配置：
<form action="upload.do" method="post" enctype="multipart/form-data"> 标题：<input type="text" name="title"><br> 文件：<input type="file" name="file"><br> <input type="submit" value="提交"> </form>
2. ActionForm中使用FormFile来接受上传文件，代码如下：
public class UploadForm extends ActionForm { private FormFile file; public FormFile getFile() { return file; } public void setFile(FormFile file) { this.file = file; }}
3. 在Action中使用FormFile来接收上传文件，代码如下:
public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) { ActionForward af = null; UploadForm uploadForm = (UploadForm) form;// TODO Auto-generated method stub FormFile myFile = uploadForm.getFile(); if(myFile!=null){ try { FileOutputStream fos = new FileOutputStream("c:\\"+myFile.getFileName()); fos.write(myFile.getFileData()); fos.flush(); fos.close(); af = mapping.findForward("success"); } catch (Exception e) { e.printStackTrace(); af = mapping.findForward("error"); } } return af; }
4. 在struts-config.xml中的配置
<action attribute="uploadForm" name="uploadForm" path="/upload" scope="request" type="com.zsw.struts.action.UploadAction" > <forward name="success" path="/upload_success.jsp" /> <forward name="error" path="/upload_error.jsp" /></action>
----------------------------------------------------------------
补充: 文件下载
//下载公文附件
public ActionForward download(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { DocumentActionForm daf = (DocumentActionForm)form; Document document = documentManager.findDocument(daf.getId()); response.reset(); response.setContentType("application/x-download;charset=GBK"); response.setHeader("Content-Disposition", "attachment;filename=temp.doc"); response.getOutputStream().write(document.getContent()); response.getOutputStream().flush(); response.getOutputStream().close(); //指示struts，不要对返回值进行处理 return null; }
