大哥们， springboot RestTemplate 的 exchange delete 可以传递 list 为参数吗

接口是这样的

    @DeleteMapping
    @ApiOperation("删除数据")
    public R<Boolean> delete(@RequestParam("idList") List<Long> idList) {
        return success(this.jobJdbcDatasourceService.removeByIds(idList));
    }

我的调用方式是这样的

@Override
    public void deleteDataSource(List<String> ids) {
        if (CollectionUtils.isEmpty(ids)){
            return;
        }
        List<Long> datasourceIds = 			   ids.stream().map(Long::parseLong).collect(Collectors.toList());
        MultiValueMap<String,Object> params = new LinkedMultiValueMap<>();
        params.add("idList",datasourceIds);
        HttpEntity<MultiValueMap<String,Object>> entity = new HttpEntity<>(params,new HttpHeaders());
        ResponseEntity<DataXResponse> exchange = restTemplate.exchange(adminServer + dataSourcePath,HttpMethod.DELETE,entity,DataXResponse.class);
        boolean isSuccess = this.handleResponse(exchange,Boolean.class);
        if (!isSuccess){
            throw new FastdataException(FastdataPlatErrorCode.REST_CALL_FAILED.getCode(),"删除失败");
        }
    }

然后服务端报错了

Caused by: java.lang.NumberFormatException: For input string: "[12]"

意思就是需要一个 list，但是接受到一个 string

有大哥遇到过这样的情况吗
