java 讀取properties文件

1.不在項目中讀取

Properties?properties?=?new?Properties();
????????????????BufferedReader?read?=?new?BufferedReader(new?InputStreamReader(new?FileInputStream("文件的路徑"),"utf-8"));
????????????????properties.load(read);
properties?.getProperty("那個文件的key")

2.在項目中讀取

InputStream?inputStream?=你那工具類的類名.class.getResourceAsStream("/文件名稱.properties");
Properties?p?=?new?Properties();
try?{
p.load(inputStream);
inputStream.close();
}?catch?(IOException?e1)?{
e1.printStackTrace();
}

都是通過p.getProperty(配置文件中的key)獲得value的
