Form requests with parameters of map type are not supported

[brucelwl]

The following is a feign interface I defined, I want to receive all the form request parameters through Map, which can run correctly in springmvc

@PostMapping(path = "/requestMap", consumes = "application/x-www-form-urlencoded")
Store requestMap(@RequestParam Map<String, String> params);

but I found that when feign client requests, the parameters are placed on the URL, not in the body of the FORM

Just make the following adjustments to solve the problem

 if (Map.class.isAssignableFrom(parameterType)) {
    if (isPostOrPutForm(method)) {
        checkState(data.queryMapIndex() == null, "Query map can only be present once.");
        data.bodyIndex(parameterIndex);
        data.bodyType(parameterType);
        data.template().header(HttpEncoding.CONTENT_TYPE, MediaType.APPLICATION_FORM_URLENCODED_VALUE);
        return true;
    }
}

 private boolean isPostOrPutForm(Method method) {
    Set<RequestMapping> requestMappings = AnnotatedElementUtils.findAllMergedAnnotations(method, RequestMapping.class);
    for (RequestMapping requestMapping : requestMappings) {
        if (isPostOrPutFormMapping(requestMapping)) {
            return true;
        }
    }
    return false;
}

// @RequestMapping + @RequestParam + Map, POST 或者 PUT 默认为FORM请求
private boolean isPostOrPutFormMapping(RequestMapping requestMapping) {
    for (RequestMethod httpMethod : requestMapping.method()) {
        if (httpMethod == RequestMethod.POST || httpMethod == RequestMethod.PUT) {
            return true;
        }
    }
    return false;
}
