java - RequestBody + JSON -


i have problem convert json java class.

controller

@requestmapping(value = "/{username}/add", method = post)     public void add(@requestbody notemodel note) {         system.out.println(note.gettitle());     }

json

{     title : "title",     text : "text" }

notemodel

public class notemodel {     private string title;     private string text;      public string gettitle() {         return title;     }      public void settitle(string title) {         this.title = title;     }      public string gettext() {         return text;     }      public void settext(string text) {         this.text = text;     } }

so, when send json controller, controller see same url, can't deserialize json java (i think). because, when try, send json - { title : "title" }, , controller wait argument - @requestbody string note, can display it.

i'm try do, in https://gerrydevstory.com/2013/08/14/posting-json-to-spring-mvc-controller/ , include adapter in servlet.xml, same effect.

ajax

$.ajax({         type : "post",         contenttype : "application/json; charset=utf-8",         url : window.location.pathname,         data : json.stringify({             title : $("#titleid").val(),             text : $("#textid").val()         }),         success: function () {             $("#titleid").val("");             $("#textid").val("");         }     })

make sure have added content-type "application/json" in header of request.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
