The front desk cannot get the data when sending a post request

Error

The front desk cannot get the data when sending a post request

Solution

For the received parameter object is a string of type Json, so you need to add @RequestBody annotation

reason

@RequestBody annotation works on the formal parameter list, inserts the HTTP request body into the method, and uses the appropriate HttpMessageConverter to write the request body into an object.
