如果properties檔案中存有中文字元，用以下程式碼讀取出來中文會出現亂碼：

public static String getString(String Name, String defaultValue) {
        String szRet = defaultValue;
        Properties prop = new Properties();
        FileInputStream fs = null;
        try {
            fs = new FileInputStream(FILE_PATH);
            prop.load(fs);
            szRet = prop.getProperty(Name, defaultValue);
        } catch
 
 (Exception e) {
            e.printStackTrace();
        } finally {
            if (fs != null) {
                try {
                    fs.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
        return szRet;
    }
 

解決方法：
將FileInputStream改為InputStreamReader

public static String getString(String Name, String defaultValue) {
        String szRet = defaultValue;
        Properties prop = new Properties();
        InputStreamReader reader = null;
        try {
            reader =  new InputStreamReader(new FileInputStream(FILE_PATH),"utf-8"
 
);
            prop.load(reader);
            szRet = prop.getProperty(Name, defaultValue);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (reader != null) {
                try {
                    reader.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
        return szRet;
    }
