java Properties 取文件为空或文件路径有空格的简单处理

Properties props = new Properties();
String url = this.getClass().getClassLoader().getResource(
"config.properties").toString().substring(6);
String empUrl = url.replace("%20", " ");// 如果你的文件路径中包含空格，是必定会报错的
System.out.println(empUrl);
InputStream in = null;
try {
in = new BufferedInputStream(new FileInputStream(empUrl));
props.load(in);
} catch (FileNotFoundException e1) {
e1.printStackTrace();
} catch (IOException e1) {
e1.printStackTrace();
}
