feign method GET must not have a request body.超过2个参数时报Method has too many Body parameters:

feign使用okhttp3的Get方式请求接口时必须加@RequestParam，否则会报错feign method GET must not have a request body，name传入null值也会报错，feign的get请求使用默认的时候，也得加@RequestParam,并且得有value，否则会报另一个错，param.value empty

public Object getParamsByAppCode(@RequestParam(value = "appCode") String appCode,@RequestParam(value = "name",required=false) String name);
