Why

It may be because there is a problem with the parameters during the query, and you need to use the specified annotation to complete the parameter transfer

Common query Bo

    public class CodeBo {
        private long start;
        private long end;

        public long getStart() {
            return start;
        }

        public void setStart(long start) {
            this.start = start;
        }

        public long getEnd() {
            return end;
        }

        public void setEnd(long end) {
            this.end = end;
        }
    }

Service provider in controller

@RestController()
@Api(tags = "Report has been Created")
@RequestMapping(value = "report", produces = MediaType.APPLICATION_JSON_VALUE)
public class ReportController {

    @GetMapping("test/test")
    List<String> listCode(@SpringQueryMap CodeBo bo){
        return new ArrayList<String>() {{
            add("AA");
            add("BB");
            add("CC");
        }};
    }
}

Feign service caller

PS: spring querymap annotation is mainly used to solve this problem

@Component
@FeignClient(value = "service")
public interface ServiceFeignClient {

    @GetMapping("test/test")
    List<String> listCode(@SpringQueryMap CodeBo bo);
}
