本文通过一个具体的Java代码示例，展示了如何使用Map集合与JSON对象进行相互转换的过程。首先，创建了一个包含三个键值对的Map，然后将其转换为JSON对象并输出。接着，将JSON字符串再次转换回Map，并从中读取原始的键值对数据。

public static void main(String[] args) throws ParseException {
       Map map = new HashMap();
       map.put("PomRefund", "1");
       map.put("PomBalance", "0");
       map.put("PomReport", "1");

       JSONObject jb = JSONObject.fromObject(map);
       String pression = jb.toString();
       System.out.println(pression);

       JSONObject json = JSONObject.fromObject(pression);
       Map p = json;

       String PomRefund = (String)p.get("PomRefund");
       System.out.println(PomRefund);

       String PomBalance = (String)p.get("PomBalance");
       System.out.println(PomBalance);

       String PomReport = (String)p.get("PomReport");
       System.out.println(PomReport);
       //{"POM_REFUND":"1","POM_BALANCE":"1","POM_REPORT":"0"}

       /*Map<String,String> params = getParams();
       sign(params);
       unsign(params);*/
       /*String bizDate = "2019-02-12 16:18:42";
       String a= bizDate.substring(0, 4);
       String b = bizDate.substring(5, 7);
       String c = bizDate.substring(8, 10);
       bizDate =a+b+c+"000000";
       String d =a+b+c+"235959";
       System.out.println(":" + bizDate);*/

       /*String a = "1011.80";
       String b = "108.66";
       if(StringUtils.isNotBlank(a) && StringUtils.isNotBlank(b)){
           BigDecimal bd1 = new BigDecimal(a);
           bd1 = bd1.setScale(2, BigDecimal.ROUND_HALF_UP);
           BigDecimal bd2 = new BigDecimal(b);
           bd2 = bd2.setScale(2, BigDecimal.ROUND_HALF_UP);
           BigDecimal bd3 =bd1.subtract(bd2);
           System.out.print(bd3);
           String bd3String = bd3.toString();
           System.out.print(bd3String);
       }*/
