json-flattener's Issues

Using '_' as a separator results in malformed result.

Input = "{"bean":{"hostname":"e46e98985","name":"898898de5","version":"5.5"},"input_type":"log","message":{"sensor_id":"p02","ts":1.519776762821703E9,"uid":"CVfeCHDFIFIfXSTcj","id_orig_h":"10.10.10.10"

output = {"bean_hostname":"e46e98985","bean_name":"e46e98985","bean_version":"5.5","[\"input_type\"]:"log","message[\"sensor_id\"]":"p02","message_ts":1519776762.821703,"message_uid":"CVfeCHDFIFIfXSTcj","message[\"id_orig_h\"]":"10.10.10.10",

It looks like values with '_ ' characters throw off the parser and it escapes the value and wraps it in brackets.

Any ideas on how to fix this. I tried a few other characters and they work fine.

issue with flattening json schema containing patternProperties regex

It seems that the key for a flattened patternProperties gets mangled as with the one herein:

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "definitions": {
    "KeyMap": {
      "type": "object",
      "additionalProperties": false,
      "properties": {
        "characteristicsFilters": {
          "type": "array",
          "minItems": 1,
          "uniqueItems": true,
          "items": {
            "$ref": "#/definitions/CharacteristicsFilter"
          }
        }
      },
      "required": ["characteristicsFilters"],
      "title": "KeyMap"
    },
    "CharacteristicsFilter": {

            "type": "string",
            "patternProperties": { "^[A-Za-z0-9 -_]+$" : {} }
          }
        }
      },
      "required": [
        "filterName",
        "values"
      ],
      "title": "CharacteristicsFilter"
    }
  },

  "title": "KeyMap",
  "type": "object",
  "additionalProperties": false,
  "properties": {
    "keyMap": { "$ref": "#/definitions/KeyMap" }
  },
  "required": ["keyMap"]

Bug with passing custom separator while flattening nested object

JsonFlattener.java:264
return new JsonFlattener(val.toString()).withFlattenMode(flattenMode).flattenAsMap();
is actually missing '.withSeparator(this.separator)', and currently flattens nested object with default dot separator.

Mb there is similar issue for print mode, also for unflattener

custom separator option?

Hello,
thnx for nice lib.
I'm using json flattening in Ruby and Java projects so that both could provide same-looking json for elasticsearch. dot-separator is a bad idea for us and ELK, in ruby gem flat_keys there is an option to set custom separator, but this lib misses it. Can it be added please?
I'll try to make a pull request.

Unflatten code is very slow compared to Flatten

Hi,

I tries to test with a Json of 25kb. I integrated this code with my service which almost becomes slow by 20 ms.

I tries to make a sample code in which flatten and unfaltten is done.

import com.fasterxml.jackson.databind.ObjectMapper;
import com.github.wnameless.json.flattener.JsonFlattener;
import com.github.wnameless.json.unflattener.JsonUnflattener;

java.lang.NoSuchFieldError: ESCAPE_JSON

When I run this code below,I got "java.lang.NoSuchFieldError: ESCAPE_JSON"

StringEscapePolicy p = StringEscapePolicy.NORMAL;

Supporting a custom ObjectMapper

Supporting a custom ObjectMapper (e.g. .withMapper(ObjectMapper mapper)) in flatten or unflatten would allow the consumer of the class to define and pass in a mapper to use. It would be particularly useful because ObjectMappers can have custom modules and deserialization/serialization features set.

Forward slash in json key gets escaped on conversion

Hi,

I am using this library to flatten a nested json and it is very useful. I have one minor issue when the JSON key contains a forward slash, i.e. /.

For ex: "{\"user/id\":123}" on flattening becomes "{\"user\\/id\":123}".

Is there a way to prevent this and retain the actual key in the final output.

Thanks,
Mayank

Flattening the parent object

When flattening a model is it currently possible to provide an object parent level entry with the flattened object as the value?

So for an model like this:

{
  "object": {
    "id": 123,
    "name": "example"
  }
}

you get:

object             ->  { "id": 123, "name": "example" }
object.id          -> 123
object.name        -> "example"

Given that the intent is to flatten the model it would also be useful to be able to specify whether to convert it to a string.

object             ->  "{ \"id\": 123, \"name\": \"example\" }"
object.id          -> 123
object.name        -> "example"

Way to exclude certain fields of json from flattening

Woule be nice to have a way to exclude some nested fields from flattening while doing flatten

Left and right bracket really have to be different?

Hi! Love your lib, it is really useful.

However, there is one thing: If I try the following, I get an error that the brackets are not allowed to be the same symbol

new JsonFlattener(line)
  .withLeftAndRightBrackets('#', '#')
  .withSeparator('_')
  .flattenAsMap()

Why is that? I can think of the brackets being the same character, which is just denoting some sort of separator.

It would be great if this could be supported in the next version, unless something speaks against it.

com.github.wnameless.json.flattener.JsonFlattener.jsonVal2Obj with double value as 0.0

Hi,
Below method is throwing number format Exception if the json value is "0.0" during jsonValue.asLong();

private Object jsonVal2Obj(JsonValue jsonValue) {
if (jsonValue.isBoolean()) return jsonValue.asBoolean();
if (jsonValue.isString()) return jsonValue.asString();
if (jsonValue.isNumber()) {
double v = jsonValue.asDouble();
if (!Double.isNaN(v) && !Double.isInfinite(v) && v == Math.rint(v))
return jsonValue.asLong();
else
return jsonValue.asDouble();
}

return null;

}

Embedded quotes are not escaped

I just started using you package and it creates invalid json when the value has embedded double quotes. I suspect there are other characters that need escaping as well. For example, I noticed all the forward slashes in my original json are escaped as well

Convert array into different objects

My use case is:
Input
{ "empId":1, "dependents":[2,3] }

Output:
{ "empId":1, "dependents":2 }
{ "empId":1, "dependents":3 }

Possible?

Add support for nested objects unflattening with null container

I noticed that it is currently impossible to unflatten the following JSON:

"outer": null,
	"outer.inner": null

the outer object is null, so the following exception is thrown: java.lang.ClassCastException: class com.fasterxml.jackson.databind.node.NullNode cannot be cast to class com.fasterxml.jackson.databind.node.ObjectNode.

Obviously, the "outer.inner": null part has been added after the flattening process. I know that the unflattening feature isn't intended to be used with arbitrary JSONs, but there are circumstances where it would be useful (in my case, I'd like to add a nested object to a flattened JSON I receive, which sometimes lacks the outer object).

Issues while Trying to run the method

When trying to call the method, I am running into this error

Error (java.lang.NoClassDefFoundError)
org/apache/commons/text/translate/CharSequenceTranslator

I downloaded the latest jar file which is version 0.5.0

Thanks

Storing the nested JSON as one of the keys as well

This might be a very specific usecase, but would it be possible to also store the nested JSON inside of the Map that gets created in flattenAsMap.

What I mean is, if this is JSON:
{ "a":{ "b":1, "c":null, "d":[ false, true ] }, "e":"f", "g":2.3 }

Currently we already get {a.b=1, a.c=null, a.d[0]=false, a.d[1]=true, e=f, g=2.3}

I would also like to add a={
"b":1,
"c":null,
"d":[
false,
true
]
},
"e":"f",
"g":2.3
} and d=[
false,
true
]

where its stored as a String so every key will have a corresponding Object in the Map that gets created. Currently, 'a' doesn't have a key because it has nested objects so there is a.b, a.c, etc but not a.

Again, I realize it might not be useful for 99% of the people, but just thought I would throw it out there.

flatten() creates illegal json when input has null character

When input has a null character:

    String json = "{\"a\":\"b\\u0000c\"}";
    System.out.println("input: " + json);
    System.out.println("output: " + new JsonFlattener(json).flatten());

The output from flatten() is an illegal json:

    input: {"a":"b\u0000c"}
    output: {"a":"b�c"}

Add intermediary object to map

When calling flattenAsMap in the json
{ "a": { "b": 1, "c": null, "d": [false, true] }, "e": "f", "g": 2.3 }
i would like to get the result
{a={b=1, c=null, d[0]=false, d[1]=true, a.b=1, a.c=null, a.d[0]=false, a.d[1]=true, e=f, g=2.3}; with the a being one of the key of the map as well. Is it possible to do it today?

Support Map<String,Object> as input for JsonUnflattener

There is a lack of API to UnFlatten a Map that has been created by processing the output of Flattened Map generated by JsonFlattener::flattenAsMap.

What is the key to search for when there is a period in the key?

I saw the EscapePolicy updates, but not sure if I am understanding it correctly.

If I have a json that looks something like

{
"test.v1": {
"_id": "test.v1"
}
}

On a flattenedJson where I have a Map<String, Object>
I would expect to be able to do something like

"test.v1._id" and value would be test.v1
In my logging of the set of keys though I see it wrapped in something else:

["test.v1"]._id is what the actual key is. How does this map to what I should be writing in String

Thanks

Mapping of timestamps

Hi,
is it possible to map Timestamp object to a date and not to number(millisecond)?

Support custom label handling for array indices?

Like we have withSeparator for nesting levels, can we have something similar for collection/array indices ?
string json = {key:[1,2,3]};
e.g. jsonflatterer.withInexSeparator('_').flat(json);

key_0 ,1 (instead of key[0] , 1)
key_1 ,2 (instead of key[1] , 2)
key_2 ,3 (instead of key[2] , 3)

Fail to Flatten Object with Field Key "root"

If there is a field called "root" anywhere in the JSON, it will not get flattened properly.

String json = "{"root":null}";
String flattened = new JsonFlattener(json).withSeparator('@').withFlattenMode(FlattenMode.KEEP_ARRAYS).flatten();
System.out.println(flattened);

flattenAsList

This repo helped me out a lot during my work today so here is my implementation for Object List flattening for your reference.

public static List<Map <String, Object>> flattenAsList(List<?> objects) {
    List<Map<String, Object>> rows = new ArrayList<>();
    for (int i=0; i<objects.size(); i++) { 
        rows.add(JsonFlattener.flattenAsMap(/* Object-to-Json Parsing */(objects.get(i)));
    }        
    return rows;
}

My full implementation using Ebean and FasterXml's Jackson (instead of EclipseResource Jsonvalue) is:

public static List<Map<String, Object>> flattenAsList(List<?> ebeans) throws JsonMappingException, IOException {
    List<Map<String, Objects>> rows = new ArrayList<>();
    for (int i=0; i<ebeans.size(); i++) {
        rows.add(JsonFlattener.flattenAsMap(Ebean.json().toJson(ebeans.get(i))));
    }
    return rows;
}

Support Java POJOs and custom map key labels using Annotations

Can we add some annotation support for Java pojos to map json keylabels to specific labels ?
e.g.
public class Test{

@ SomeAnnotation("myCustomLabel")
private Integer myField = 3;
}

JsonFlattener.flatten(new Test());
should produce Map with myCustomLabel, 3

Unflat no working with Mapobject

{"certificateAuthority" : {
"data" : "abcd"
}
}
Hi , using JsonUnflattener on json will provide --->
{
"certificateAuthority.data": "abcd"
}

but when you use JsonUnflattener on this flat result this an exception java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.node.ObjectNode.isEmpty()Z

on previous version this error message was different ("" is not an resource object")

Thanks

Option to not escape JSON strings in keys

Please allow users to avoid escaping JSON keys, so that we can use String literals like "姓名" as keys, without doing any crazy string manipulation.

Issue in unflattening json

Issue while unflattening Json data:

When I tried this Json to unflatten using unflattening library,
it produces the following error :

Exception in thread "main" java.lang.UnsupportedOperationException:
Not an object: null

{
"course.List[5].type":"B",
"course.List[1].type":"C"
}

Denormalizing the Child with immediate parent

For example,

Input JSON - { "a": { "b": 1, "c": null, "d": [false, true] }, "e": "f", "g": 2.3 }
Flattened JSON - { "a.b": 1, "a.c": null, "a.d[0]": false, "a.d[1]": true, "e": "f", "g": 2.3 }

Is it possible to convert the above input JSON into the following structure ?

{"a.b": 1, "a:c": null, "e": "f", "g": 2.3}
{"a.b": 1, "a:c": null, "e": "f", "g": 2.3, "a.d": false}
{"a.b": 1, "a:c": null, "e": "f", "g": 2.3, "a.d": true}

array of objects does not support same key

String json = "{ "measurements" : { "name" : "fromState", "value": "AB", "name" : "toState","value": "BC"}}";
String flattenedJson = JsonFlattener.flatten(json);

Gives:

{"measurements.name":"toState","measurements.value":"BC"}

I expected to have both values included.

Slash in json value will prefix backslash after flatten

It's nice to have json flatten library.
Just notice that Apache NiFi 'FlattenJson' processor utilize this library to flat json.

Recently I've been working on some features update on this processor.
I noticed that if there is a slash at input json value.
Output will prefix every slash with a backslash .

For example,
input text:
{"innerClass":{},"col3":["http://localhost:8080/test1","http://localhost:8080/test2"]}
output text in dot notation:
{"innerClass":{},"col3[0]":"http://localhost:8080/test1","col3[1]":"http://localhost:8080/test2"}
(Message didn't show precisely in this text dialog there is actually backslash exist before slash)

Not sure if it's expected behavior.
But to me, it looks like data un-match problem.
This happens to all 3 flatten mode.

Please let me know your feedback.
Thanks.

[Question] : Can the separator for unflattener be a String ?

Is there a reason why the separator should not be a String ? if no, can it be made a String ?

Issue with empty json array .

While do the flatten this library removing empty json array if our input contain empty valued json array .So we are getting miss match data if we compare un flattened data with actual input .

Option to not flatten arrays

My use case wants to flatten the keys, but keep all values as they are. Could you please offer a configuration option to keep array values under the same key?

grouping according to keys

is there a way such that we can group all the values for a key type into a list ?
for example consider the json below ⬇️

{"data":
[
{
    "Name": "crunchify.com",
    "Author": "App Shah",
    "Address": "New York"
},
{
    "Name": "crunchify.com",
    "Author": "App Shah",
    "Address": "New York"
}
]
}

the output is ⬇️

data[0].Address : New York
data[0].Author : App Shah
data[0].Name : crunchify.com
data[1].Address : New York
data[1].Author : App Shah
data[1].Name : crunchify.com

can i group the data into lists such as

Address = [New York , New York]
Author = [App Shah , App shah]
Name = [crunchify.com , crunchify.com]

Can we have getters on Point or PointBuilder class

Hi,

I use some generic code to parse json object to Point, we found it's difficult to verify the Point object after the parsing logic when we try to write test for the parsing. If we can have the Point's getters exposed, our life would be much easier.

Thanks
Alex

[Question] - how can I use json-flattener with JAX-RS?

I was wondering, what is the best method to override JAX default @javax.ws.rs.Consumes({MediaType.APPLICATION_JSON}) with json-flattener?

Maybe we could use a Jackson custom JsonSerializer? I am very new to Java so im not sure if that would be a feasible idea.

Thanks!

Missing Field in version 0.4.0

Its working fine with 0.1.0 version but somehow failing with 0.4.0 version.

Below is the stack trace :
Caused by: java.lang.NoSuchFieldError: ESCAPE_JSON

[Bug] flattenAsMap produces escaped field names for field names that contain dot

Here's a code sample to demonstrate the issue.

public static void main(String[] args) throws Exception {
	final ObjectMapper mapper = new ObjectMapper();
	/*
	 * The input is just a simple json object { "a.b": 1 }
	 */
	final String jsonString = "{ \"a.b\": 1 }";
	final String flattenedString = JsonFlattener.flatten(jsonString);
	/*
	 * The following line prints
	 * {"[\"a.b\"]":1}
	 *
	 * No problem here.
	 */
	System.out.println(flattenedString);
	/*
	 * Print the only field name in the flattened json. It prints
	 * ["a.b"]
	 *
	 * No problem here either.
	 */
	System.out.println(mapper.readTree(flattenedString).fieldNames().next());
	final Map<String, Object> flattenedMap = JsonFlattener.flattenAsMap(jsonString);
	/*
	 * Print the only field name in the flattened map. It prints
	 * [\"a.b\"]
	 *
	 * And here's the problem. For some reason the quotes in the field name in the
	 * flattened map got unnecessarily escaped.
	 */
	System.out.println(flattenedMap.keySet().iterator().next());
	/*
	 * Just to confirm this, I'm parsing the map into json and printing the json.
	 * It prints
	 * {"[\\\"a.b\\\"]":1}
	 *
	 * So yes, the flattened map field name got unnecessarily escaped
	 */
	System.out.println(mapper.writeValueAsString(mapper.valueToTree(flattenedMap)));
}

So the gist of the issue is that, when you have a field name with a dot, the flatten method flattens things correctly, but flattenAsMap produces a Map with field names that got unnecessarily (and incorrectly) escaped.

Flattener.withSeparator breaking when nested JSON key has separator char in it.

Hi,

I was trying out the withSeparator functionality, turns out that it doesn't work correctly for few cases. Whenever we're using a separator and the nested JSON key has that separator, it breaks.

Eg. withSeparator('_')

Eg. {"a": 45, "b": {"c": "val"}}; // works fine in this case.
Output: {"a": 45, "b_c": "val"}

Eg. {"a": 45, "b": {"c_type": "val"}} // breaks since nested field c_type has an _ in it.
Output: {"a":45,"b["c_type"]":"val"}

This is the case whenever the separator char is present in one of the field key.

asLong

Thanks for your work on this great library. It seems very useful.

However, I am having a problem...

My json looks like this (obfuscated):
{"39473331":{"mega":6.0,"goals":1.0}}

and I am getting this exception:

Caused by: java.lang.NumberFormatException: For input string: "6.0"
at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
at java.lang.Long.parseLong(Long.java:589)
at com.eclipsesource.json.JsonNumber.asLong(JsonNumber.java:61)
at com.github.wnameless.json.flattener.JsonFlattener.jsonVal2Obj(JsonFlattener.java:174)

Now I was looking at your code and I've seen this here:

  double v = jsonValue.asDouble();
  if (!Double.isNaN(v) && !Double.isInfinite(v) && v == Math.rint(v))
    return jsonValue.asLong();
  else
    return jsonValue.asDouble();

Shouldn't it be the other way around? Like this:
if (!Double.isNaN(v) && !Double.isInfinite(v) && v == Math.rint(v))
return v;
else
return jsonValue.asLong();

In any case, it shouldn't try to parse 6.0 as a long.

performance of json flattener

Have you done any performance benchmark of this son flattener. When we ran it against a high volume json events stream to flatten, its taking significant time. I think it creates a lot of JsonFlatten object and the parser it uses is probably not the fastest.

JsonUnflattener fail to unflatten flatten string with KEEP_ARRAYS

Original: {"a":[1,2,3],"b":[{"c":{"d":[1,2]}}]}
Flattened with KEEP_ARRAYS: {"a":[1,2,3],"b":[{"c.d":[1,2]}]}
Unflattened: {"a":[1,2,3],"b":[{"c.d":[1,2]}]}

JsonUnflattener does not unflatten object in the array "b".

Question: How to get index from a key when using JsonFlattener.flattenAsMap

Keys from Map are printed as [index].keyname. How to get the index value from keys?

Code:

Map<String, Object> flattenedJsonMap = JsonFlattener.flattenAsMap(response.readEntity(String.class));

Map<String,Object> keysMap = new HashMap<>();
flattenedJsonMap.forEach(
       (k, v) -> keysMap.put(k, v)
);

for (String kval : keysMap.keySet()) {
    if (kval.contains("paper_id")) {
           System.out.println("\nkval="+kval+"\n"+keysMap.get(kval));
    }
}

Sample output

kval=[3].paper_id
01e3b313e78a352593be2ff64927192af66619b5

kval=[1].paper_id
004f0f8bb66cf446678dc13cf2701feec4f36d76

kval=[2].paper_id
01d162d7fae6aaba8e6e60e563ef4c2fca7b0e18

Wanted to get the total or get the index values (1,2,3 etc) from key ([1].paper_id)
