springboot后端接收前端传数组参数方法

1:：前端传数组参数用ids,不要用ids[],因为是传数组会自动加上[]

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

2：使用postman传数组有三种方法

2-1：方法一，后端使用@RequestParam接收传参

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

2-2：方法二，后端使用@RequestParam接受收传参

与@RequestBody不同，@RequestParam传递的数组中有多少个值，便排排下来写便是
（注意微操，参数名需为key的名称为@RequestParam括号里的名称，而不是定义的数组名）

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

2-3：方法三，后端使用@RequestBody接受收传参

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