Bukkit / Spigotplugin - 从配置中删除条目

Question

我正在开发 Bukkit / Spigotplugin，它允许用户投票。该插件使用配置。我想删除一个条目，但它不起作用。我在 Google 上发现的内容：

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:

- Sllikson
OpenForVoting: false

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)

也不行。

我做错了什么？

Answer 1

ConfigurationSection 的设置方法更改了您想要的值，但是在保存配置时它将覆盖所有当前值。这意味着如果你想保留它们，你必须 edit/specify 每个值，否则它们将会丢失。为了只需要编辑单个值，我使用了一个数组。

数组是用来存放临时数据的，你好像需要一个包含String name和int votes的对象，我称这个对象为VoteData.

服务器启动时，加载配置并用结果填充数组。这允许我们在运行时删除对象或修改数组，而无需触及配置文件，从而提高性能。

private void loadConfig() {

    voteDataArray = new ArrayList<VoteData>();
    YamlConfiguration config = YamlConfiguration.loadConfiguration(yourConfigFile);

    ConfigurableSection section = config.getConfigurableSection("ThingsYouCanVoteFor");
    if(section == null) {
        Bukkit.getLogger().warn("ConfigSection ThingsYouCanVoteFor doesn't exist");
        return;
    }

    for(String num : section.getKeys(false)) {

        String name = section.getString(num + ".name");
        int votes = section.getDouble(num + ".votes");

        voteDataArray.add(new VoteData(name, votes));

    }
}

当服务器关闭或您需要时，通过循环 config.getKeys(false) 并将节点设置为您的数据值来保存包含数组内容的配置。

private void saveConfig() {

    YamlConfiguration config = new YamlConfiguration();

    int num = 1;
    for(VoteData data : voteDataArray) {
        config.set("ThingsYouCanVoteFor." + num + ".name", data.getName());
        config.set("ThingsYouCanVoteFor." + num + ".votes", data.getVotes());
        num++;
    }

    try {
        config.save(yourConfigFile);
    } catch (IOException e) {
        e.printStackTrace();
    }
}

现在当你需要使用插件中的数据时，使用数组而不是配置。当你想删除一些东西时，只需从数组中删除即可。

您可以使用以下方法简单地删除路径中的值：

config.set(pathToRemove, null);
