You are posting JSON, not form data, but you are trying to read the ArrayList<Keys>as a form parameter.
您正在发布 JSON，而不是表单数据，但您正在尝试将其ArrayList<Keys>作为表单参数读取。
Try changing your method signature from:
尝试更改您的方法签名：
public ResponseEntity<String> addKeys(@RequestParam(value="keys") ArrayList<Keys> keys){
to
到
public ResponseEntity<String> addKeys(@RequestBody Keys[] keys){
That may not work since your JSON has an object that has a keysproperty that is the list of keys. So you could try to change your ajax post data to something like
这可能不起作用，因为您的 JSON 有一个具有keys键列表属性的对象。因此，您可以尝试将 ajax 发布数据更改为类似
data: JSON.stringify(tmpList)
so that you are just posting the list instead of wrapping it in another object that has the keys element.
这样您就可以发布列表，而不是将其包装在另一个具有 keys 元素的对象中。
