3Configuration自定义配置

在配置文件config.yml中写一点信息：

这个文件不同于plugin.yml

yunfei:
  list: #list
    - 1
    - 2
    - abc
  map: #MapList
    - { name: senko, count: 1, speed: 3.3f }
    - { name: senko2, count: 2, speed: 2.2f }
  age: 11         #11
  disabled: false #false

主类中读取配置文件信息：

    /**
     * 使用{@link YamlConfiguration}对象的get函数来获取yaml属性。
     */
    private void testGetConfigYaml() {
        Logger logger = getLogger();
        // 通过JavaPlugin#getConfig函数获取的配置文件只能是config.yml
        FileConfiguration config = getConfig();
        List<?> list = config.getList("yunfei.list");
        logger.info("==========yunfei.list===========" + list.size());
        for (Object o : list) {
            logger.info("Result：" + o + "| 类型为：" + o.getClass().getName());
        }

        List<Map<?, ?>> mapList = config.getMapList("yunfei.map");
        logger.info("==========yunfei.map===========" + mapList.size());
        for (int i = 0; i < mapList.size(); i++) {
            StringBuilder sb = new StringBuilder();
            Set<?> keys = mapList.get(i).keySet();
            Collection<?> values = mapList.get(i).values();
            sb.append("，map的keys：");
            keys.forEach((e) -> sb.append(e).append(" "));
            sb.append("，map的values：");
            values.forEach(e -> sb.append(e).append(" "));
            logger.info("当前map：" + i + sb);
        }
        logger.info("==========yunfei.age===========" + config.getInt("yunfei.age"));
        logger.info("==========yunfei.disabled===========" + config.getBoolean("yunfei.disabled"));
    }

保存并持久化文件：

    private void testSaveAndSaveDefaultConfig() {
        // config.yml
        FileConfiguration config = getConfig();

        // 更新JavaPlugin#newConfig对象的属性值
        config.set("yunfei.disabled", true);

        // 覆盖保存
        saveConfig();
    }

自定义配置文件custom-config.yml：

    /**
     * 自定义的配置文件，活学活用{@link #getDataFolder()}函数
     */
    private void testCustomConfigYaml() {
        YamlConfiguration myConfig = new YamlConfiguration();
        myConfig.set("yunfei.age", 13);
        myConfig.set("yunfei.status", "unknown");
        try {
            myConfig.save(new File(getDataFolder(), "custom-config.yml"));
            YamlConfiguration newConfig = new YamlConfiguration();
            newConfig.load(new File(getDataFolder(), "custom-config.yml"));
            System.out.println(ChatColor.GREEN + " " + newConfig.get("yunfei.age"));
            System.out.println(ChatColor.GREEN + " " + newConfig.get("yunfei.status"));
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
