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")publicResult<?>delete(@RequestParam(name ="ids[]", required =true)ArrayList<Integer> ids){
        sysStudyTestFileService.removeBatchByIds(ids);returnResult.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")publicResult<?>delete(@RequestParam(name ="ids[]", required =true)ArrayList<Integer> ids){
        sysStudyTestFileService.removeBatchByIds(ids);returnResult.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")publicResult<?>delete(@RequestParam(name ="ids[]", required =true)ArrayList<Integer> ids){
        sysStudyTestFileService.removeBatchByIds(ids);returnResult.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")publicResult<?>delete(@RequestBodyArrayList<Integer> ids){
        sysStudyTestFileService.removeBatchByIds(ids);returnResult.ok("删除成功");}
