body: <p>My question is, can you change the structure of the response of the 401 error message?</p>
  
  <pre><code>{
      "error": "unauthorized",
      "error_description": "No AuthenticationProvider found for org.springframework.security.authentication.UsernamePasswordAuthenticationToken"
  }
  </code></pre>
  
  <p>for example </p>
  
  <pre><code>{
      "timestamp" : 123124354,
      "status" : 401,
      "message" : "The username or password are not valid!"
  }
  </code></pre>
