springBoot配置从配置文件中获取key及value值

springBoot中同时获取key及value值存入map中，配置文件（文件在resource下）如下：

=19931216
=19940912
=20210505

加载配置工具类：

/**

public class PropertiesUtils {

    protected Logger logger = (getClass());
    public Properties properties;
    private String[] resourcesPaths;

    // 无参构造
    public PropertiesUtils() {
    }

    // 传入配置文件名称，可以多个
    public PropertiesUtils(String... resourcesPaths) {
        load(resourcesPaths);
    }

    // 加载配置文件信息
    private void load(String[] resourcesPaths) {
         = resourcesPaths;
        properties = new Properties();
        for (String location : resourcesPaths) {
            InputStream is = null;
            try {
                is = new FileInputStream(getAbsolutePath(location));
                (is);
            } catch (IOException ex) {
                ("Could not load properties from path:" + location + ", " + ());
            } catch (Exception ex) {
                ("Could not load properties from path:" + location + ", " + ());
            } finally {
                (is);
            }
        }
    }

    // 获取根据key获取value
    public Object getValue(String key) {
        if ((key)) {
            return (key);
        }
        return "";
    }

    // 获取文件绝对路径
    public String getAbsolutePath(String filename) throws URISyntaxException {
        if (!(filename)) {
            filename = ().getResource(filename).toURI().getPath();
        }
        return filename;
    }

    public static void main(String[] args) {
        long startTime = ();
        PropertiesUtils properties = new PropertiesUtils("", "");
        Iterator<Entry<Object, Object>> map = ().iterator();
        while (()) {
            Entry<Object, Object> entry = (); // 遍历获取key value
            Object key = ();
            Object value = ();
            (key + "=" + value);
        }
        ("load time :" + (() - startTime) + "ms");
    }
}

如果配置文件key或value含有中文，可以把中文转为ASCII代码中获取到的就是中文（否则会乱码，ASCII与中文互转网站点此），如下：
