I have a small web app built using Spring, and the REST services are accessible from curl and postman. If I try to access them using the JavaScript hosted on my web app I get a 405 error. What could cause this?
I realize there are insecurities in the code, this is just a rushed class project so they are not important.
If I copy the JavaScript code and run it in the console of the browser it works.

Cross origin must include your js hosted server address like
Ex - #CrossOrigin(origins="http://localhost:3000)
and add it after the #RestController
Check your js code.
If you look at your controller, it's declared #PostMapping. Make sure your js code is calling the same POST method.
Check if you are returning a #ResponseBody or a #ResponseStatus
To fix this simply add a #ResponseBody
#RequestMapping(value="/user", method = RequestMethod.POST)
public #ResponseBody String updateUser(#RequestBody User user){
return userService.updateUser(user).getId();
}
or a #ResponseStatus to your method.
#RequestMapping(value="/user", method = RequestMethod.POST)
#ResponseStatus(value=HttpStatus.OK)
public String updateUser(#RequestBody User user){

I'm creating a quiz app and I want to filter my database questions in order by level and cateogory but I don't know how to do it. I've already implemented the levelRef to get the level and display it on screen.
I also want to fetch the category and filter the questions (e.g: if user taps on sport I'll display only sport questions).
Here's my code
`private void updateQuestion(){
countDownTimer.cancel();
mQuestionRef = new Firebase("https://quizer-f3732.firebaseio.com/Questions/" + mQuestionNumber + "/question");

I have some angular code that asks for user name input:
playCtrl.js
var myApp = angular.module('myApp');
/*
* CONTROLLERS METHOD
*/
myApp.controller('PlayController', ['$scope', '$http', function($scope, $http) {
var REQUEST_SERVICE_URI = '/Project2/play.do';
//var REQUEST_SERVICE_URI = 'http://13.59.197.145:8085/Project2/#/play';
var playerObject = {} // create playerObject
$scope.message = "Let's play!";
$scope.message2 = "Please enter your name";
$scope.user = {
userid: '',
username: '',
roleId: '',
statusId: ''
};
$scope.register = function() {
playerObject = $scope.user; // adding user to a playerObject
console.log('playerObject.name: ' + playerObject.name);
//console.log('playerObject: ' + $scope.user.name);
console.log("REGISTER BUTTON WAS CLICKED");
$http.post(REQUEST_SERVICE_URI, playerObject).
then(function(playerObject) {
alert("SUCCESS");
//$scope.user = data;
});
}
}])
Then I have my SpringController.java that's trying to get this user object:
#RestController
public class SpringController {
// has to accept
#RequestMapping(headers="Accept=application/json", value="/play.do", method = RequestMethod.POST)
public String registerUser(Users user, BindingResult bindingResult, ModelMap modelMap, HttpSession session){
Register r = new Register();
System.out.println("TRYING TO CREATE A USER: " + user);
if(r.createUser(user.getUsername())){
session.setAttribute("username", user.getUsername());
session.setAttribute("role", user.getRole());
session.setAttribute("status", user.getStatus());
System.out.println("Created user: " + user.getUsername());
return "lobby";
}else{
return "login";
}
}
My console DOES print out everything in the angularjs perfectly fine, and it also prints "TRYING TO CREATE A USER: " + user from the java side, however it shoes that all everything is null: TRYING TO CREATE A USER: Users [userid=0, username=null, roleId=null, statusId=null]
(my user create implementation only needs a username, all others can be null)
Here's my web.xml:

How would I go about sending the object properly?
I just figured it out: I had to add #RequestBody within the () of my SpringController method, and change the input from Object to String type:
public String registerUser(#RequestBody String username, BindingResult bindingResult, ModelMap modelMap, HttpSession session)
When I try to register a new user in my app, throw mySQL db the application doesn't work and sends this error message:

I am building a chat app. I have a client (Ionic 2) talking to a server (Java). The client can receive messages successfully from the server (e.g. "Welcome to the chat!" is received when connecting), but when I try send a message to the server from the client, it does not get there (the DataListener<Message> is not being invoked on the "chat_message:send" event.).
Please any suggestions?
Server Code:
import com.corundumstudio.socketio.AckRequest;
import com.corundumstudio.socketio.Configuration;
import com.corundumstudio.socketio.SocketIOClient;
import com.corundumstudio.socketio.SocketIOServer;
import com.corundumstudio.socketio.listener.ConnectListener;
import com.corundumstudio.socketio.listener.DataListener;
import com.corundumstudio.socketio.listener.DisconnectListener;
public class Server {
public static void main(String[] args) {
Configuration config = new Configuration();
config.setHostname("localhost");
config.setPort(3700);
final SocketIOServer server = new SocketIOServer(config);
server.addConnectListener(new ConnectListener() {
#Override
public void onConnect(SocketIOClient client) {
System.out.println("onConnected");
client.sendEvent("chat_message:message", new Message("Welcome to the chat!"));
}
});
server.addDisconnectListener(new DisconnectListener() {
#Override
public void onDisconnect(SocketIOClient client) {
System.out.println("onDisconnected");
}
});
server.addEventListener("chat_message:send", Message.class, new DataListener<Message>() {
#Override
public void onData(SocketIOClient client, Message data, AckRequest ackSender) throws Exception {
System.out.println("onSend: " + data.toString());
server.getBroadcastOperations().sendEvent("chat_message:message", data);
}
});
System.out.println("Starting server...");
server.start();
System.out.println("Server started");
}
}
and
public class Message {
private String message;
public Message(String message) {
this.message = message;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
Client Code:
import { Component, NgZone } from '#angular/core';
import { Http } from "#angular/http";
import { MessageModel } from '../model/messageModel';
import { UtilityService } from '../utils/utilityService';
declare var io;
#Component({
templateUrl: 'build/pages/chat/chat.html',
providers: [UtilityService]
})
export class ChatPage {
private socketHost: string = "http://localhost:3700";
private messages: MessageModel[] = [];
private zone: NgZone = null;
private chatBox: string = null;
private socket: any = null;
private utilityService: UtilityService = null;
constructor(http: Http, utilityService: UtilityService) {
this.utilityService = utilityService;
this.setUpMessageService(http);
}
setUpMessageService(http: Http): void {
this.messages = [];
this.zone = new NgZone({ enableLongStackTrace: false });
let url = this.socketHost + "/fetch";
http.get(url).subscribe((success) => {
var data = success.json();
console.log(data);
for (var i = 0; i < data.length; i++) {
this.messages.push(data[i].message);
}
}, (error) => {
console.log(JSON.stringify(error));
});
this.chatBox = "";
this.socket = io(this.socketHost);
this.socket.on("chat_message:message", (messageModel: MessageModel) => {
this.zone.run(() => {
console.log('run: ' + messageModel);
this.messages.push(messageModel);
});
});
}
send(msg) {
if (msg && msg != "") {
let messageModel: MessageModel = new MessageModel();
messageModel.message = msg;
console.log(messageModel);
this.socket.emit("chat_message:send", messageModel);
}
this.chatBox = "";
}
}
and
import { Injectable } from "#angular/core";
#Injectable()
export class MessageModel {
public message: string = null;
}
If I send the message as a String and not a MessageModel from the client it works.
