標籤：struts for 檔案大小 沒有 BMI object private app 多檔案
和單個檔案上傳配置都是一樣的，只是在action中接受參數時候，接受的是數組，不再是單個的檔案。
一，action的實現：
public class MutableFilesUpload extends ActionSupport {private static final long serialVersionUID = 1L;public File[] uploadObjects;public String[] uploadObjectsFileName;public String[] uploadObjectsContentType;public String moreInfo;public String upload() {System.out.println(moreInfo);// 1.拿到ServletContextServletContext servletContext = ServletActionContext.getServletContext();// 2.調用realPath方法，擷取根據一個虛擬目錄得到的真實目錄String realPath = servletContext.getRealPath("/files");// 3.如果這個真實的目錄不存在，需要建立File file = new File(realPath);if (!file.exists()) {file.mkdirs();}// 4.把檔案存過去// 剪下：把臨時檔案剪下指定的位置，並且給他重新命名。 注意：臨時檔案沒有了for (int i = 0; i < uploadObjects.length; i++) {System.out.println("one file name: " + uploadObjectsFileName[i]);uploadObjects[i].renameTo(new File(file, uploadObjectsFileName[i]));}return SUCCESS;}}
二，配置action
<action name="mutable_uploads" class="gy.upload.MutableFilesUpload" method="upload"> <!-- 指定（限制）上傳檔案的類型，定義局部攔截器，修改預設攔截器的屬性 "fileUpload.maximumSize" ：限制上傳最大的檔案大小。 "fileUpload.allowedTypes"：允許上傳檔案的類型。 "fileUpload.allowedExtensions"：允許上傳檔案的可擴充檔案類型。 --> <interceptor-ref name="defaultStack"> <param name="fileUpload.maximumSize">500000000</param> <param name="fileUpload.allowedTypes">text/plain,application/vnd.ms-powerpoint</param> <param name="fileUpload.allowedExtensions">.txt,.ppt</param> </interceptor-ref> <result>/success.html</result> <!-- 出現錯誤自動會返回input結果，進入結果檢視 --> <result name="input">/fail.html</result></action>
三，表單的實現
<body><form action="mutable_uploads" method="post"enctype="multipart/form-data">檔案：<br> <input type="file" name="uploadObjects"><br><input type="file" name="uploadObjects"><br> more info:<input type="text" name="moreInfo"><br><input type="submit" value="提交"><br></form></body>
