在顺序:

您可以将文件存储在几乎任何地方。 不需要延期。 Montecristo已经说明了如何加载这个。这应该没问题。 propertyNames()提供了一个用于迭代的枚举。

下面是遍历属性的另一种方法:

Enumeration eProps = properties.propertyNames();
while (eProps.hasMoreElements()) { 
    String key = (String) eProps.nextElement(); 
    String value = properties.getProperty(key); 
    System.out.println(key + " => " + value); 
}

读取属性文件并将其内容加载到properties

String filename = "sample.properties";
Properties properties = new Properties();

input = this.getClass().getClassLoader().getResourceAsStream(filename);
properties.load(input);

下面是遍历Properties的有效方法

    for (Entry<Object, Object> entry : properties.entrySet()) {

        System.out.println(entry.getKey() + " => " + entry.getValue());
    }

如果将属性文件放在与类Foo相同的包中，就可以轻松地加载它

new Properties().load(Foo.class.getResourceAsStream("file.properties"))

鉴于Properties扩展了哈希表，您可以以与在哈希表中相同的方式遍历值。

如果你使用*。你可以获得编辑器支持，例如Eclipse有一个属性文件编辑器。

You can store the file anywhere you like. If you want to keep it in your jar file, you'll want to use Class.getResourceAsStream() or ClassLoader.getResourceAsStream() to access it. If it's on the file system it's slightly easier. Any extension is fine, although .properties is more common in my experience Load the file using Properties.load, passing in an InputStream or a StreamReader if you're using Java 6. (If you are using Java 6, I'd probably use UTF-8 and a Reader instead of the default ISO-8859-1 encoding for a stream.) Iterate through it as you'd iterate through a normal Hashtable (which Properties derives from), e.g. using keySet(). Alternatively, you can use the enumeration returned by propertyNames().
