How to send POST-request with request arguments using cURL?
Analysis
Long story short, conceptually, @RequestParam and @RequestBody are mutually exclusive: query parameters (@RequestParam) are sent as a request body.
Please see the additional details here:

Solution
Currently, there are two alternatives:
- Stick to the request parameters (
@RequestParam) only: pass every parameter (i.e. every JSON property) as a query parameter. Stick to the request body (
@RequestBody) only, for example:- Pass everything as a JSON request body.
- Pass everything as a JSON request body, except the
user_idparameter. The parameter may be made@PathVariableand the@RequestMappingshould use the appropriate placeholder to reference it.
