Well, first of all, your method is marked with a
..., method = RequestMethod.PUT.
Accordingly, it will only accept PUT requests.
Secondly, you send the BODY in the request, but not the parameters of the requests. But in the signature of your method, you say that the method parameters must be taken from the query string (the @RequestParam annotation tells us about this).
Thus, in order for the method to work in this form, you need to PUT the request with the parameters in the query string. The query string will look something like this:
/update?&readTimestamp=54645646&meteoStationId=4545&pressuere=4564564&etc.
If you want to send data in JSON, and receive it in a method from the request body, then it's better to create a Measurement class, for example. Put in it those fields that you now have described in the method signature. And bring the signature of the update method to the form:
I hope I explained clearly...
