解決方法:讓action傳回string,而不是modelandview.
修改後的action:
public string upload(
string content = null;
objectmapper mapper = new objectmapper();
map.put("filename", "a");
content = mapper.writevalueasstring(map);
system.out.println(content);
} catch (jsongenerationexception e) {
} catch (jsonmappingexception e) {
} catch (ioexception e) {
// modelandview modelandview = new modelandview(
// new mappingjacksonjsonview(), map);
return content;
