1:：前端傳數組參數用ids,不要用ids[],因為是傳數組會自動加上[]

	@ApiOperation(value = "批量刪除", notes = "批量刪除")
    @DeleteMapping(value = "/batchDelete")
    public Result<?> delete(@RequestParam(name = "ids[]", required = true) ArrayList<Integer> ids) {
        sysStudyTestFileService.removeBatchByIds(ids);
        return Result.ok("刪除成功");
    }

2：使用postman傳數組有三種方法

2-1：方法一，后端使用@RequestParam接收傳參

	@ApiOperation(value = "批量刪除", notes = "批量刪除")
    @DeleteMapping(value = "/batchDelete")
    public Result<?> delete(@RequestParam(name = "ids[]", required = true) ArrayList<Integer> ids) {
        sysStudyTestFileService.removeBatchByIds(ids);
        return Result.ok("刪除成功");
    }

2-2：方法二，后端使用@RequestParam接受收傳參

與@RequestBody不同，@RequestParam傳遞的數組中有多少個值，便排排下來寫便是
（注意微操，參數名需為key的名稱為@RequestParam括號里的名稱，而不是定義的數組名）

    @ApiOperation(value = "批量刪除", notes = "批量刪除")
    @DeleteMapping(value = "/batchDelete")
    public Result<?> delete(@RequestParam(name = "ids[]", required = true) ArrayList<Integer> ids) {
        sysStudyTestFileService.removeBatchByIds(ids);
        return Result.ok("刪除成功");
    }

2-3：方法三，后端使用@RequestBody接受收傳參

    @ApiOperation(value = "批量刪除", notes = "批量刪除")
    @DeleteMapping(value = "/batchDelete")
    public Result<?> delete(@RequestBody ArrayList<Integer> ids) {
        sysStudyTestFileService.removeBatchByIds(ids);
        return Result.ok("刪除成功");
    }
