創(chuàng)建上傳頁面upload.jsp代碼

<form action="test/upload.action" method="post" enctype="multipart/form-data"> <input type="file" name="upload"><br/> <input type="submit" value="上傳"> </form> 注意：此處設置form表單enctype="multipart/form-data"屬性文件上傳action類 uploadfile.java代碼

public class UploadFile extends ActionSupport {private File upload;private String uploadFileName;public File getUpload() {return upload;}public void setUpload(File upload) {this.upload = upload;}public String getUploadFileName() {return uploadFileName;}public void setUploadFileName(String uploadFileName) {this.uploadFileName = uploadFileName;}public String execute() throws Exception {String parentFilepath = ServletActionContext.getServletContext().getRealPath("/upload");// 獲取當前服務器目錄真實路徑 upload是存放上傳文件的文件夾System.out.println(parentFilepath + "--parent filepath--");File parentFile = new File(parentFilepath);// 構造upload目錄System.out.println(this.getUploadFileName() + "--upload filename--");File uploadFile = new File(parentFile, this.getUploadFileName());// 通過upload目錄和文件名構建目標文件if (!parentFile.exists())parentFile.mkdir();// 如果upload目錄不存在 則創(chuàng)建一個目錄FileUtils.copyFile(this.getUpload(), uploadFile);// 將要上傳的文件復制到目標文件return SUCCESS;} }struts.xml配置代碼

<action name="upload" class="hxlzp.uploadfile.UploadFile"> <result name="success">/index1.jsp</result> </action>返回頁面代碼

<img alt="" src="upload/<s:property value ="uploadFileName" /> ">
