Javaでsrcフォルダのファイルを取得する方法

参考コード:
public final Map<String,String> fileToMap(Map<String,String> map) throws Exception{
if(map == null){

map = new HashMap<String,String>();
}
InputStream isr = null;
Reader r = null;
try {
isr = PropertiesServlet.class.getClassLoader().getResourceAsStream(“/message.properties”);
r = new InputStreamReader(isr, “UTF-8”);
Properties props = new Properties();
props.load(r);
Set<Entry<Object, Object>> entrySet = props.entrySet();
for (Entry<Object, Object> entry : entrySet) {
if (!entry.getKey().toString().startsWith(“#”)) {

map.put(((String) entry.getKey()).trim(), ((String) entry

.getValue()).trim());
}
}
return map;

} finally {
if (r != null) {

try {

r.close();

} catch (IOException e) {

HLogger.error(e);

}
}

if (isr != null) {

try {

isr.close();

} catch (Exception e2) {

HLogger.error(e2);

}

}

}

}
