jspsmart的使用
上傳
// 新建一個SmartUpload對象
SmartUpload su = new SmartUpload();
// 上傳初始化
su.initialize(pageContext);
// 限制每個上傳文件的最大長度。
su.setMaxFileSize(10000);
// 限制總上傳數據的長度。
su.setTotalMaxFileSize(20000);
// 設定允許上傳的文件（通過擴展名限制）,僅允許doc,txt文件。
su.setAllowedFilesList("doc,txt");
// 設定禁止上傳的文件（通過擴展名限制）,禁止上傳帶有exe,bat,
//jsp,htm,html擴展名的文件和沒有擴展名的文件。
su.setDeniedFilesList("exe,bat,jsp,htm,html,,");
// 上傳文件
su.upload();
// 將上傳文件全部保存到指定目錄
int count = su.save("/upload");
下載
// 新建一個SmartUpload對象
SmartUpload su = new SmartUpload();
// 初始化
su.initialize(pageContext);
// 設定contentDisposition為null以禁止瀏覽器自動打開文件，
//保證點擊鏈接后是下載文件。若不設定，則下載的文件擴展名為
//doc時，瀏覽器將自動用word打開它。擴展名為pdf時，
//瀏覽器將用acrobat打開。
su.setContentDisposition(null);
// 下載文件
su.downloadFile("/upload/test.doc");
