How to create an object class that can converted to json like this in java? [duplicate]

This question already has answers here:
Is there a way to create the bean class from a json response
(6 answers)
Closed 3 years ago.
This is the JSON request that I need to pass to other API, My problem is I dont know how to create an object that can have other object inside.
What is the best approach for this, I'll be using ObjectMapper to convert the object into json like this.
{
"request": {
"head": {
"version": "1.0.0",
"function": "sample.function",
"clientId": "clientId",
"clientSecret": "clientSecret",
"reqTime": "2001-07-04T12:08:56+05:30",
"reqMsgId": "reqMessageID",
"reserve": ""
},
"body": {
"occurTime": "2018-03-04T12:08:56+08:00",
"bizScene": "SAMPLE_BIZ",
"envInfo": {
"tokenId": "jkahsdhsjakdhkjsajdsahdkjsakdhsa===",
"clientIp": "127.0.0.1",
"appVersion": "v0.1.0",
"terminalType": "NOP"
},
"extendInfo": {
"PSID":"87943297427",

"mobtelUnlinkingDate" : "2018-04-04T12:08:56+08:00",
"activeLinkedMobtel" : "123756"
},
"accountInfo": {
"userMobile": "123756"
},
"operationInfoDTO" : {
"operationOrigin": "TWEETER",
},
"operationType": "SAMPLE",
"operationResult": "FALSE",
}
},
"signature": "signature string"
}

I gave a name to the root Object a used this website to generate boilerplate bean object
"rootObj":{
"request": {
"head": {
"version": "1.0.0",

"clientId": "clientId",

There are some minor syntax errors in your JSON example in line 33 and 36.
JSON doesn't like comma after the last element of a list or dictionary.
If you remove those and use this JSON as input for http://www.jsonschema2pojo.org/ you'll get corresponding Java classes.

Json query String for getting value with Condition

I want to get the value of vehicleCodeelement where vehicleLease is AS PER LAW OF ENFORCMENT.
Could someone please help me with JSON query ?
Please find JSON data below.
{
"StateOffers": [
[{
"vehicleCode": 242214214,
"vehiclePart": [{
"#type": "vehiclePart",
"segments": [{
"#type": "Segment"
"segmentOfferInformation": {
"vehicleMiles": 771,
"awardFare": false
},
"vehicleLease": "AS PER LAW OF ENFORCMENT"
}
],
"stops": 0
}
]
}, {
"vehicleCode": 242214214,
"vehiclePart": [{
"#type": "vehiclePart",
"segments": [{
"#type": "Segment"
"segmentOfferInformation": {
"vehicleMiles": 771,
"awardFare": false
},
"vehicleLease": "MY RULE MY WORLD"
}
],
"stops": 0
}
]
}
]
]
}
This is the expression I have tried:
$..vehicleCode[?($..vehicleLease=="AS PER LAW OF ENFORCMENT")

Having trouble accessing fields of JSON using groovy

I'm trying to extract the information from an API response using groovy
I want to get to the info stored under the "res" key.
Something along the lines of body.measures.02:00:00:02:06:70.res
Can not figure out have to access this information without throwing a nullpointerexception.
"body":[ {
"_id":"70:ee:50:01:fe:96",
"place":{
"location":[
-70.863189,
42.273936
],
"altitude":26.154942,
"timezone":"America\/New_York"
},
"mark":12,
"measures":{
"02:00:00:02:06:70":{
"res":{
"1506611038":[
22,
66
]
},
"type":[
"temperature",
"humidity"
]
},
"06:00:00:01:97:28":{
"wind_strength":15,
"wind_angle":343,
"gust_strength":29,
"gust_angle":301,
"wind_timeutc":1506611083
},
"70:ee:50:01:fe:96":{
"res":{
"1506611086":[
1007.4
]
},
"type":[
"pressure"
]
}
},
"modules":[
"02:00:00:02:06:70",
"06:00:00:01:97:28"
],
"module_types":{
"02:00:00:02:06:70":"NAModule1",
"06:00:00:01:97:28":"NAModule2"
}
}
],
"status":"ok",
"time_exec":0.017483949661255,
"time_server":1506611446
}

body is an array with one element in your case, so you have to do body[0].measures.'02:00:00:02:06:70'.res, e. g. like
new groovy.json.JsonSlurper().parseText('''{"body":[ {
"_id":"70:ee:50:01:fe:96",
"place":{
"location":[
-70.863189,

},
"mark":12,
"measures":{
"02:00:00:02:06:70":{
"res":{

"res":{
"1506611086":[
1007.4
]
},
"type":[
"pressure"
]
}
},
"modules":[
"02:00:00:02:06:70",
"06:00:00:01:97:28"
],
"module_types":{
"02:00:00:02:06:70":"NAModule1",
"06:00:00:01:97:28":"NAModule2"
}
}
],
"status":"ok",
"time_exec":0.017483949661255,
"time_server":1506611446

Parsing Json data giving ClassCastException

I am currently using the following JSON parser but keep getting the error Caused by: java.lang.ClassCastException: java.lang.String cannot be cast to org.json.JSONObject. How can I fix this, it has worked many times before.
ublic List<String> handleResponse(HttpResponse response)
throws ClientProtocolException, IOException {
List<String> result = new ArrayList<String>();
String JSONResponse = new BasicResponseHandler()
.handleResponse(response);
try {
// Get top-level JSON Object - a Map
JSONObject responseObject = (JSONObject) new JSONTokener(
JSONResponse).nextValue(); //Problem Line
JSONObject item1 = responseObject.getJSONObject("searchResult");
// Extract value of "Item" key -- a List
JSONArray items = item1
.getJSONArray("Item");
Below is what I'm looking to parse

Why do you need a JSONTokener? This is much easier:
JSONObject responseObject = new JSONObject(JSONResponse);
JSONArray main = responseObject.getJSONArray("findItemsAdvancedResponse");
JSONObject result = main.getJSONObject(0).getJSONArray("searchResult").getJSONObject(0);
JSONArray items = result.getJSONArray("item");

Your nextValue() method must be returning a String, which you are then trying to cast to a JSONObject. I would start by splitting the statement up into smaller statements to help isolate the issue. You are instantiating a new object, calling a method on it, and type casting all on the same line. That makes code harder to debug.
JSONTokener tokener = new JSONTokener(JSONResponse);
Object obj = tokener.nextValue();
if(obj.getClass().equals(JSONObject.class))
{
JSONObject responseObject = (JSONObject)obj;
}
else
{
System.out.println("Not a JSONObject");
}

Serialization of Chart configuration in Vaadin

I use Vaadin 7. I want to save a Chart configuration and restore it later. I found an interesting thing in com.vaadin.addon.charts.model.Configuration is that you can serialize the configuration into JSON object.
Code :
chart.getConfiguration().toString();
Result:
{
"type": "column"
},
"title": {
"text": "Chart"
},
"xAxis": {
"categories": [
"f",
"e"
],
"axisIndex": 0
},
"yAxis": {
"min": 0,
"title": {
"text": "Quantity"
},
"axisIndex": 0
},
"tooltip": {
"_fn_formatter": "this.series.name +\u0027: \u0027+ this.y +\u0027 (\u0027+ Math.round(this.percentage) +\u0027%)\u0027"
},
"plotOptions": {
"column": {
"stacking": "normal"
}
},
"series": [
{
"data": [
1,
2
],
"name": "d",
"visible": true
}
],
"exporting": {
"enabled": false
}
}
What I want now is build Configuration from that JSON object. Is there a way to that ?

Found it, pretty simple actually :
Chart chart = new Chart();
//json is the string containing your JSON object
chart.setJsonConfig(json);
//you'll have to draw the chart to update it if needed
//chart.drawChart();
