GET request does not support object parameter passing problem @ GetMapping ("/ getByParam") String hello (Student student) throws Exception

As above, the feign call reported an error of500.

Solution method

Add @ SpringQueryMap

@ GetMapping ("/ getByParam") String hello (@ SpringQueryMap Student student) throws Exception;feign @ RequestMapping (value= "/ test", method = RquestMethod.GET) Result getA (String id) when sending a get request

As above, call this method to report an error in the request method post error, please use get.

Cause analysis

Feign converted the get method to post, resulting in an error.

The main reason for this problem is that the connection tool implementation class, which is used by Feign by default, finds that as long as you have a corresponding GET body object, you will force the GET request to be converted into a body request.

When the Feign source code parses the interface with the @ FeignClient annotation, when creating the proxy object, when the proxy object parses the parameter containing the @ RequestParam annotation, it will enhance the parameter to url instead of passing it as body.

The problem is solved after adding @ RequestParam

The modified code is as follows.

@ RequestMapping (value= "/ test", method = RquestMethod.GET) Result getA (@ RequestParam String id). The above article is about how to solve the problem of feign GET requests that do not support passing parameters to objects. I believe you all have some understanding.
