Should @RequestParam or @RequestBody be used for POST requests in Spring Boot?

@RequestBody requires that a class be created for the JSON body to deserialize into, while @RequestParams do not.

Which one should be used for POST requests, assuming that the params don’t need to be obfuscated? Does it matter? Is either one recommended over the other?

@RequestParam , you can use when you want to map from the GET/POST request to your method argument and you can set some default value to it in case you are not passing any argument. @RequestBody, you can use when you are expecting an object as it will automatically deserializes the json into a java type.

No it doesn't. You can e.g. deserialize into a Map or a List, depending on the JSON.

Which one should be used for POST requests?

That depends on the Content-Type (mime type) of the request.

Does it matter?

Yes.

Is either one recommended over the other?

For mime types application/x-www-form-urlencoded and multipart/form-data you should use @RequestParam.

For anything else, you need to use @RequestBody.
