在项目文件夹中找不到java文件

1 月 Questions & Answers 1284

我有一个加载配置的函数。但是，它给了我一个FileNotFoundException，我不知道为什么。我的方法如下：

public static Configfile configuration() {
        String server = null;
        int dbport = 0;
        String dbuser = null;
        String dbpass = null;

        Properties prop = new Properties();
        InputStream input = null;

        try {
            input = new FileInputStream("config.properties");
            prop.load(input);

            server = prop.getProperty("server");
            dbport = Integer.parseInt(prop.getProperty("dbport"));
            dbuser = prop.getProperty("dbuser");
            dbpass = prop.getProperty("dbpassword");
        } catch (IOException ex) {
            ex.printStackTrace();
        } finally {
            if (input != null) {
                try {
                    input.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
        return new Configfile(server, dbport, dbuser, dbpass);
    }

还有我的配置。属性文件位于：

E:\Android\NSomething5

我错过了什么
