预读Json配置文件

1.读取配置文件，将文件内容转化为String

public static String ReadFile(String path){BufferedReader reader = null;String laststr = "";//System.out.println("ClassLoader.getSystemResource() :"+ClassLoader.getSystemResource(""));try{InputStream input = ClassLoader.getSystemClassLoader().getResourceAsStream(path);//FileInputStream fileInputStream = new FileInputStream(path);InputStreamReader inputStreamReader = new InputStreamReader(input, "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;}

3.转化文件内容(这里将文件内容转化为Json)

public final static JsonArray elves_value_js ;static{String elves_value_str = ReadFile("resource/elves_value.json");elves_value_js = JSONArray.fromObject(elves_value_str);}
