How to send POST request by Spring cloud Feign

Question

It\'s my Feign interface

@FeignClient(
        name=\"mpi\",
        url=\"${mpi.url}\",
        configuration = FeignSimpleEncoderConfig.class
)
public inte         


        

Answer 1

First of all you should change your Feign interface like this:

@FeignClient (
    configuration = FeignSimpleEncoderConfig.class
)
public interface MpiClient {
   @RequestMapping(method = RequestMethod.POST)
   ResponseEntity getPAReq(Map queryMap);
}

Then you should set the encoder during feign configuration:

public class FeignSimpleEncoderConfig {
    @Bean
    public Encoder encoder() {
        return new FormEncoder();
    }
}
