从 .properties 文件中读取多个帐户的用户名和密码

Question

我遇到以下问题。我有一个configuration.properties 文件，我想在我的应用程序中读取它。它的形式如下：

accountNames = account1, account2, account3
account1.userName = testUserName
account1.password = testUserPassword
account2.userName = secondTestUserName
account2.password = secondTestUserPassword
account2.userName = thirdTestUserName
account2.password = thirdTestUserPassword

如何读取所有帐户并将 userName-userPassword 对存储在 HashMap 中？如我所见，我有一个二维数组。我对访问帐户每个属性的代码特别感兴趣。

编辑：我已将configuration.properties 文件更改为以下格式：

userNames = testUserName, secondTestUserName, thirdTestUserName
testUserName = testUserPassword
secondTestUserName = secondTestUserPassword
thirdTestUserName = thirdTestUserPassword

处理此问题的代码如下：

    properties.load(new FileInputStream(configFilePath));
    for(String s : properties.getProperty("userNames").split(",")){
        clientCredentials.put(s.trim(), properties.getProperty(s.trim()));
    }

    //test:
    for(String s:clientCredentials.keySet()){
        System.out.println("Key: "+s+" & value: "+clientCredentials.get(s));
    }

感谢您的帮助。

如果您只关心用户名和密码，请尝试以下操作：

    final Map<String, String> accounts = new HashMap<String, String>();
    final File pwdFile = new File("path to your user/password file");
    BufferedReader br = null;
    try
    {
        br = new BufferedReader(new FileReader(pwdFile));

        br.readLine();// you don't need the first line

        while (true)
        {
            String  line = br.readLine();
            if (line == null)
                break;//end of file have been reached

            final String user = line.split("=")[1].trim();

            line = br.readLine();
            if (line == null)// pwd is missing
                throw new Exception("Invalid pwd file");

            final String pwd = line.split("=")[1].trim();
            accounts.put(user, pwd);

        }

    }
    catch (final Exception e)
    {
        // add your own error handling code here
        e.printStackTrace();
    }
    finally
    {
        if (br != null)
            br.close();

    }

此代码假定包含用户名的行后面将紧跟一行包含前一行用户名的密码的行。
