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阅读。它具有以下形式：

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

如何阅读所有帐户并将对帐户userName-userPassword存储在HashMap中？在我看来，我有一组二维数组。我特别感兴趣的是访问帐户的每个属性的代码。

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();

    }

此代码假设包含用户名的行后面会紧跟一行，其中包含上一行用户名的密码。
