我用struts2文件作文件上传碰到在局域网和本机文件都能上传，但是到了外网上，有些文件就不能上传。
java类public abstract class AbstractIOAction extends AbstractAction { private static final long serialVersionUID = -6516966167635959378L;
private File uploadFile;// 实际上传文件
private String uploadFileContentType; // 文件的内容类型
private String uploadFileFileName; // 上传文件名
private String fileType;// 上传文件选择类型 0:CSV, 1:DBF, 2:excel public File getUploadFile() {
return uploadFile;
} public void setUploadFile(File uploadFile) {
this.uploadFile = uploadFile;
} public String getFileType() {
return fileType;
} public void setFileType(String fileType) {
this.fileType = fileType;
} public String getUploadFileContentType() {
return uploadFileContentType;
} public void setUploadFileContentType(String uploadContentType) {
this.uploadFileContentType = uploadContentType;
} public String getUploadFileFileName() {
return uploadFileFileName;
} public void setUploadFileFileName(String uploadFileFileName) {
this.uploadFileFileName = uploadFileFileName;
} public String uploadFile() throws Exception {
if (!doFileUpload()) {
return INPUT;
}
return SUCCESS;
} /**
* 上传文件
*
* @return
* @throws IOException
*/
protected boolean doFileUpload() throws IOException {
initPath();
String targetDirectory = ServletActionContext.getServletContext().getRealPath("/upload");
String targetFileName = uploadFileFileName.substring(0, uploadFileFileName.lastIndexOf(".")) + "_" + UserContext.getUser().getUsername() + uploadFileFileName.substring(uploadFileFileName.lastIndexOf("."));
File target = new File(targetDirectory, targetFileName);
FileUtils.copyFile(uploadFile, target);
setUploadFileFileName(targetFileName);
return true;
} /**
* 初始化文件夹
*/
protected void initPath() {
// 文件夹不存在就自动创建：
ServletContext context = ServletActionContext.getServletContext();
if (!new File(context.getRealPath("/upload")).isDirectory()) {
new File(context.getRealPath("/upload")).mkdirs();
}
if (!new File(context.getRealPath("/download")).isDirectory()) {
new File(context.getRealPath("/download")).mkdirs();
}
}
}推测是uploadFileFileName值没拿到
我的struts文件配置：<action name="DataImport" class="com.zksoft.web.action.data.DataImportAction">
<interceptor-ref name="fileUploadStack">
<param name="maximumSize">204800000</param>
</interceptor-ref>
<result name="success" type="redirect">
<param name="location">${location}</param>
</result>
<result name="input">/major_dic_import.html</result>
</action>
