如何在Java中将json数组转换为有序集合

Question

I have a scenario in java web service to accept json object as input.Here json object doesn't ensure order.so is there any provision to convert this input json object to an ordered collection in java before reading it?

@Post

public Representation updateTestData(JSONObject entity) {
    Representation rep = null;
    JSONObject reqText;
    try {
        reqText = entity;
  //when i'm reading the json object. attributes and  values of json are not in order as that in submit
        log.info("input data: " + reqText);         
                } catch (Exception e) {
        e.printStackTrace();
        log.error("EXCEPTION CAUGHT WHILE UPDATETESTDATA: " + getRequest().getResourceRef().toString()
                + " message: " + e.getMessage());
    }
    return rep;
}

Answer 1

If you can modify the json structure, change it like this: [{key:value},{key2:value},...] , this ensures the order. But if not, then you have to put an additional array to store the order. it looks dumb though. hope it helps.

Answer 2

在Json Object中，Element未按排序顺序
