java读取项目资源文件的方法

1、把资源文件放在项目的Resource文件夹下，并使其设置成为资源文件夹（通过idea或者eclise）
2、

Thread.currentThread().getContextClassLoader().getResourceAsStream("")方法。具体如下：

public static String getGeoJson(String fileName) {
    BufferedReader reader = null;
    String laststr = "";
    try {
        InputStream is = Thread.currentThread().getContextClassLoader().getResourceAsStream("geo/" + fileName);
        InputStreamReader inputStreamReader = new InputStreamReader(is, "UTF-8");
        reader = new BufferedReader(inputStreamReader);
        String tempString = null;
        while ((tempString = reader.readLine()) != null) {
            laststr += tempString;
        }
        reader.close();
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        if (reader != null) {
            try {
                reader.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
    return laststr;
}
