<span style="font-size:18px;"><!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Insert title here</title> </head> <body> <form action="/upload.do" method="POST" enctype="multipart/form-data"> <input type="file" name="myfile"> <input type="submit"/> </form> </body> </html></span>
routes路由表 post /upload.do controllers.xxx.upload
後臺實現：
<span style="font-size:18px;">public static Result upload() throws IOException{ MultipartFormData body = request().body().asMultipartFormData(); FilePart filepart = body.getFile("myfile"); if (filepart != null) { String fileName = filepart.getFilename(); String contentType = filepart.getContentType(); File file = filepart.getFile();//獲取到預設上傳儲存的完整檔案路徑，這只是個臨時檔案 BufferedInputStream is=new BufferedInputStream(new FileInputStream(file)); File newFile=new File("e://upload/"+filepart.getFilename());//要儲存的檔案路徑 BufferedOutputStream os=new BufferedOutputStream(new FileOutputStream(newFile)); byte[] b = new byte[1024]; while(is.read(b)!=-1){ os.write(b); } is.close(); os.close(); return ok("File uploaded"); } else { flash("error", "Missing file"); return ok("aa"); } }</span>
