用Java读取属性文件

Question

我有以下代码尝试读取属性文件：

Properties prop = new Properties();

ClassLoader loader = Thread.currentThread().getContextClassLoader();           

InputStream stream = loader.getResourceAsStream("myProp.properties");

prop.load(stream);

我在最后一行有一个例外。特别：

Exception in thread "main" java.lang.NullPointerException

at java.util.Properties$LineReader.readLine(Properties.java:418)

at java.util.Properties.load0(Properties.java:337)

at java.util.Properties.load(Properties.java:325)

at Assignment1.BaseStation.readPropertyFile(BaseStation.java:46)

at Assignment1.BaseStation.main(BaseStation.java:87)

谢谢，尼科斯
