title: simple push notification in spring
body: <p>I have a project that is related to job postings. Consultants or employers register on my website and then start posting jobs. I want to make push notifications for all users.  When a consultant or employer posts a job, all online users must get notified that an employer has posted this job without any page refreshes on jquery setInterval or timeout.</p>
  
  <p>I am using Spring framework. I have searched for the solution but found nothing. I want to know whether Spring provided WebSockets in their latest version. Is this possible to do with WebSockets?</p>
  
  <p>I want a proper resource so that I can implement it on my website.</p>
