这里只介绍一种方式,json转map

下面俩包 自行下载

下面是测试类(key是id)

	public String Chang(String key){
		BufferedReader reader = null;
		try {
			reader = new BufferedReader(new FileReader(".\\src\\pro.js"));
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		StringBuilder sb=new StringBuilder();
		String line=null;
		try {
			while((line=reader.readLine())!=null){
				//把换行符去掉
				  sb.append(line);
				}
			reader.close();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		String str = sb.toString();
		String newStr = str.substring(1,str.length()-1); 
		  Map map = FastJsonUtil.stringToCollect(newStr);
		  String value = (String) map.get(""+key+"");
		return value;
	}
