本文介绍了一个用于批量上传文件夹内的文件到数据库的方法，该方法通过递归遍历指定路径下的所有文件，并根据文件类型判断是否进行上传操作。文章详细展示了如何设置文件属性并插入到数据库中。

DBOperation.java中的一个方法

public void alluponefile(String filesb, HttpServletRequest request, String typeid, String secondid, String levelid) { DBOperate dbo = new DBOperate(); String filesbs = filesb.replace("//", "/"); // filesbs+sub[i] int lastseparator = filesbs.lastIndexOf("/"); String dirfilesb = filesbs.substring(0, lastseparator); File dir = new File(dirfilesb); HttpSession session = request.getSession(); manager manager1 = (manager) session.getAttribute("manager"); String sub[] = dir.list(); for (int i = 0; i < sub.length; i++) { if (new File(dirfilesb + "/" + sub[i]).isFile())// 是文件就添加 {

int lastdot = sub[i].lastIndexOf("."); String title = sub[i].substring(0, lastdot); String content = sub[i]; String filesrc = dirfilesb + "/" + sub[i]; String format = sub[i].substring(lastdot + 1); if (format.equals("rar") || format.equals("doc") || format.equals("zip")) // 限制上传文件的格式 { Source_inf inf = new Source_inf();// 向数据库中插入一条条的数据 try { inf.setFilesrc(new String(filesrc.getBytes("gb2312"), "iso-8859-1")); inf.setFormats(format); inf.setSizes(2 + "KB"); // 本地上传的文件不知道大小 inf.setFilename(new String(title.getBytes("gb2312"), "iso-8859-1")); if (!typeid.equals("")) { inf.setTypeid(PubFunc.parseInt(typeid)); } else { if (!secondid.equals("")) { inf.setTypeid(PubFunc.parseInt(secondid)); } else { inf.setTypeid(PubFunc.parseInt(levelid)); }

} inf.setContent(new String(content.getBytes("gb2312"), "iso-8859-1")); inf.setDatetime(new java.util.Date().toLocaleString()); inf.setState("1"); inf.setNewss("1"); inf.setRedian("0"); inf.setAuthor(new String(manager1.getUsername() .getBytes("gb2312"), "iso-8859-1")); inf.setNumbers(1); inf.setShenhe(1); dbo.insert_update(inf, "insert");

}

catch (UnsupportedEncodingException e) { e.printStackTrace(); } }

}

else // 是目录就 { String infilesb = (dirfilesb + "/" + sub[i] + "/234.rar") .replace("//", "/"); alluponefile(infilesb, request, typeid, secondid, levelid);//自己调用自己,递归 }

}

使用

public ActionForward uploadallsource(ActionMapping actionMapping, ActionForm actionForm, HttpServletRequest request, HttpServletResponse response) throws Exception { DBOperate dbo = new DBOperate(); String levelid = request.getParameter("levelid"); String secondid = request.getParameter("secondid"); String typeid = request.getParameter("typeid"); //重点:文件夹的名字传 String filesb=request.getParameter("filesb"); String filesbs=filesb.replace("//","/"); //filesbs+sub[i] int lastseparator=filesbs.lastIndexOf("/"); String dirfilesb=filesbs.substring(0, lastseparator); dbo.alluponefile(filesb,request,typeid,secondid,levelid); Log log1 = new Log(); HttpSession session = request.getSession(); manager manager1=(manager)session.getAttribute("manager"); log1.setUsername(manager1.getUsername()); log1.setDatetime(new java.util.Date().toLocaleString()); log1.setAction(new String(("批量添加下载资源<font color='#FF0000'><strong>" + new String(dirfilesb.getBytes("iso-8859-1"),"gbk") + "</strong>--" + "</font>目录下的文件成功！").getBytes("gbk"),"iso-8859-1")); dbo.insert_update(log1, "insert"); PrintWriter out=response.getWriter(); out.println("<script>"); out.println("alert('add success!!');"); out.println("window.location.href='/web/admin/allup.jsp'"); out.println("</script>"); // response.sendRedirect("/web/admin/allup.jsp"); return actionMapping.findForward("");

}
