该博客主要介绍了如何将一个JSON字符串转换为Map对象。通过使用JSONObject类将JSON解析为Map，然后遍历Map的每个条目，进一步解析包含在其中的子订单信息。最后，将所有子订单信息存储到一个ArrayList中，并将其添加到主订单Map中。

public Map<String,Object> pareseJson(String message) {
    Map<String,Object> orderMap = new HashMap<String, Object>();//主订单
   List<Map<String,Object>> orderItemList = new ArrayList<Map<String, Object>>();//子订单
    Map<String,Object> map =new HashMap<String, Object>();
    JSONObject CustomerOrder = JSONObject.fromObject(message);

    Map<String, Object> CustomerMap = JSONObject.fromObject(CustomerOrder);

    for(Map.Entry<String,Object> entry : CustomerMap.entrySet()){
        Object customer = entry.getValue();
        JSONObject jsonObjectCustomer = JSONObject.fromObject(customer);
        Map<String, Object> orderMapJson = JSONObject.fromObject(jsonObjectCustomer);
        System.out.println("KEY:"+entry.getKey()+"  -->  Value:"+entry.getValue()+"\n");
        for(Map.Entry<String, Object> entry1:orderMapJson.entrySet()){
            if("Products".equals(entry1.getKey())){
                Object product = entry1.getValue();
                JSONObject orderItem = JSONObject.fromObject(product);
                Map<String,Object> orderItemMap = JSONObject.fromObject(orderItem);
                ObjectMapper mapper = new ObjectMapper();
                //List<LinkedHashMap<String, Object>> list = mapper.readValue(message, List.class);
