Leetcode146. LRU 缓存

1、发送get请求时，后端可用List<T>来接收参数，前端或者其他请求可通过逗号分割参数即可；同时注意特殊字符转换，如日期格式

接收方（后端）：

  @ApiOperation(value = "手动计算扩缩容", notes = "手动计算扩缩容")
    @GetMapping(value = "/resource/hand")
    public HttpResponse<Object> scaleResource(@RequestParam(name = "ips", required = false) @ApiParam(value = "ip") List<String> ips,
                                      @RequestParam(name = "businesses", required = false)  @ApiParam(value = "业务") List<String> businesses,
                                      @RequestParam(name = "startDate", required = false) @DateTimeFormat(iso = DateTimeFormat.ISO.DATE) @ApiParam(value = "开始时间", format = "yyyy-MM-dd", example = "2024-01-01") LocalDate startDate,
                                      @RequestParam(name = "endDate", required = false) @DateTimeFormat(iso = DateTimeFormat.ISO.DATE) @ApiParam(value = "结束时间", format = "yyyy-MM-dd", example = "2024-01-01") LocalDate endDate,
                                      @RequestParam(name = "createdBy") @ApiParam(value = "操作人", required = true) String createdBy,
                                      @RequestParam(name = "resourceType", required = false) @ApiParam(value = "资源类型") String resourceType,
                                              @RequestParam(name = "description", required = false) @ApiParam(value = "描述") String description) {
        try{
            if(Objects.isNull(startDate) && Objects.nonNull(endDate)){
                return new HttpResponse<>().error(400, "结束时间不为空时，开始时间也不能为空");
            }
            if(Objects.nonNull(startDate) && Objects.isNull(endDate)){
                return new HttpResponse<>().error(400, "开始时间不为空时，结束时间也不能为空");
            }
            List<Scale> list = scaleService.scaleResource(ips, businesses, startDate, endDate, createdBy, resourceType, description);
            return new HttpResponse<>().success(list);
        }catch (Exception e){
            return new HttpResponse<>().error(500, e.getMessage());
        }
    }

调用方（页面）：

public String handScaleInfo(){
        logger.info("手动计算扩缩容操作开始...");
        // session中获取用户ID
        String userId = ((UserBean) ServletActionContext.getRequest()
                .getSession().getAttribute(SessionKeys.userInfo.toString()))
                .getUserId();
        if (userId == null || userId == "") {
            logger.error("创建人信息为空，手动扩缩容失败");
            errMsg = "创建人信息为空，手动扩缩容失败";
            return ConstantEnum.ERROR.toString();
        }
        handScale.setCreatedBy(userId);
        Integer pageNum = getPage();
        Integer pageSize = getPageSize();
        String urlParams = Util.getUrlParams(handScale, pageNum, pageSize,"startTime");
        String url = scaleUrl + "/scale/resource/hand/" + urlParams.replace(" ", "%20").replace(":", "%3A");;
        String response = Util.doGet(url);
        if (StringUtils.isNotEmpty(response)) {
            HttpResponse httpResponse = JSON.parseObject(response, HttpResponse.class);
            if (200 == httpResponse.getCode()) {
                result.setResultFlage(ConstantEnum.SUCCESS.toString());
                result.setResultMessage(getText("resourceAnalysis.opt.success"));
            } else {
                result.setResultFlage(ConstantEnum.FAILURE.toString());
                result.setResultMessage(getText("resourceAnalysis.http.fail"));
                return ConstantEnum.FAILURE.toString();
            }
        } else {
            result.setResultFlage(ConstantEnum.FAILURE.toString());
            result.setResultMessage(getText("resourceAnalysis.http.fail"));
