Struts2 多文件上传，Struts2文件上传,1、建一个上传页面mul
1、建一个上传页面multiUpload.jsp
<body> <h4>this is the fileupload2.jsp for many file</h4> <form action="fileupload" method="post" enctype="multipart/form-data"> username : <input type="text" name="username" ><br> file1 : <input type="file" name="file"><br> file2 : <input type="file" name="file"><br> file3 : <input type="file" name="file"><br> <input type="submit" value="submit"><br> </form> </body>
2、写对应的action处理类：
public class UpLoad2Action extends ActionSupport { private String username; private List<File> file; private List<String> fileFileName; private List<String> fileContentType; public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public List<File> getFile() { return file; } public void setFile(List<File> file) { this.file = file; } public List<String> getFileFileName() { return fileFileName; } public void setFileFileName(List<String> fileFileName) { this.fileFileName = fileFileName; } public List<String> getFileContentType() { return fileContentType; } public void setFileContentType(List<String> fileContentType) { this.fileContentType = fileContentType; } @Override public String execute() throws Exception { for (int i = 0; i < file.size(); i++) { InputStream is = new FileInputStream(file.get(i)); String root = ServletActionContext.getRequest().getRealPath("/upload"); File dest = new File(root, fileFileName.get(i)); OutputStream os = new FileOutputStream(dest); byte[] buffer = new byte[1024]; int len = 0; while ((len = is.read(buffer)) != -1) { os.write(buffer, 0, len); } is.close(); os.close(); } return SUCCESS; }}3、配置struts.xml文件：
<action name="fileupload" class="com.strong.action.UpLoad2Action"> <result name="success">/present2.jsp</result> </action>
4、显示页面：
<body> <h4>this is the fileUploadResult2.jsp</h4> username : <s:property value="username"/><br> <!-- 迭代去取上传文件的名字 ，--> <s:iterator value="fileFileName" id="f"> fileName: <s:property value="#f"/><br> </s:iterator> </body>
