 8     public static void main(String [] args) {
 9         //读取数据库参数配置
10         InputStream inputStream =  TestProperties.class.getClassLoader().getResourceAsStream("jdbc.properties");
11         
12         Properties p = new Properties();
13         try{
14             p.load(inputStream);
15             System.out.println(p.getProperty("db.username"));
16             System.out.println(p.getProperty("db.password"));
17             System.out.println(p.getProperty("db.dataBaseName"));            
18             System.out.println(p);
19         }catch (IOException e) {
20             e.printStackTrace();
21         }
22         
23     }
24 }

db.username=root
db.password=
db.dataBaseName = jeesite

运行结果：
