springboot 遍历接收到的Map，删除对应的键值对

@XxxMapping("/xxx")

public xxx Xxxx(@Request Map<Object, Object> map){

　　Set<Object> keys = map.keySet();

　　Iterator<Object> iterator = keys.iterator();

　　while(iterator.hasNext()){

　　　　Object key = iterator.next();

　　　　Object value = map.get(key);

　　　　if(key.equals("xxx")){iterator.remove();}

　　}

}
