java - Bukkit/Spigotplugin - 从配置中删除条目

Question

我正在开发一个 Bukkit/Spigotplugin，它允许用户投票。 该插件使用一个配置。我想删除一个条目，但它不起作用。 我在 Google 上找到的内容:

getConfig().set("your.value", null);

我实现了什么:

int i = id;
while(getConfig().contains("ThingsYouCanVoteFor." + (i + 1)))
{
    getConfig().set("ThingsYouCanVoteFor." + Integer.toString(i) + ".name", getConfig().getString("ThingsYouCanVoteFor." + Integer.toString(i + 1) + ".name"));
    getConfig().set("ThingsYouCanVoteFor." + Integer.toString(i) + ".votes", getConfig().getInt("ThingsYouCanVoteFor." + Integer.toString(i + 1) + ".votes"));
    i++;
}
getConfig().set("ThingsYouCanVoteFor." + Integer.toString(i + 1), null);
saveConfig();
sender.sendMessage("§aRemoved ID " + id);

配置的外观:

ThingsYouCanVoteFor:
  0:
    name: Build a bridge
    votes: 0
  1:
    name: Kill the owner
    votes: 2
  2:
    name: Vote for something other
    votes: 1
  3:
    name: Remove all banned peoples inventory
    votes: 0
  4:
    name: Teleport to others home
    votes: 0
  5:
    name: Dig a hole in the air
    votes: 0
  6:
    name: Shutdown the internet
    votes: 0

OpenForVoting: false

当我使用“/voteadmin remove 3”时它应该是什么样子:

ThingsYouCanVoteFor:
  0:
    name: Build a bridge
    votes: 0
  1:
    name: Kill the owner
    votes: 2
  2:
    name: Vote for something other
    votes: 1
  3:
    name: Teleport to others home
    votes: 0
  4:
    name: Dig a hole in the air
    votes: 0
  5:
    name: Shutdown the internet
    votes: 0
PeopleWhoVoted:
- Gamingwelle

- Sllikson
OpenForVoting: false

它的外观:

ThingsYouCanVoteFor:
  0:
    name: Build a bridge
    votes: 0
  1:
    name: Kill the owner
    votes: 2
  2:
    name: Vote for something other
    votes: 1
  3:
    name: Teleport to others home
    votes: 0
  4:
    name: Dig a hole in the air
    votes: 0
  5:
    name: Shutdown the internet
    votes: 0
  6:
    name: Shutdown the internet
    votes: 0

使用

getConfig().getConfigurationSection("ThingsYouCanVoteFor").getKeys(false).remove(i + 1)

也不起作用。

我做错了什么？

您可以使用以下方法简单地删除路径中的值:

config.set(pathToRemove, null);
