后台实现:
<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();//获取到默认上传保存的完整文件路径,这只是个临时文件
BufferedInputStream is=new BufferedInputStream(new FileInputStream(file));
File newFile=new File("e://upload/"+filepart.getFilename());//要保存的文件路径
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>
