有些文件不需要配置，只需要放到resources下面

InputStream is = this.getClass().getClassLoader().getResourceAsStream(mappingFilePath);
InputStreamReader isr = new InputStreamReader(is, "UTF-8");
BufferedReader br = new BufferedReader(isr);
while ((thisLine = br.readLine()) != null) {
    String[] strs = thisLine.split("::");
    String requestPath = strs[0].toLowerCase();
    String serviceName = strs[1];
    this.mapping.put(requestPath, serviceName);
}
