I need to handle, in my .net WCF service, JSON data (POST request) from a third party application.
Basically the third party app would be consuming my WCF service.
The posted JSON data structure is known.
I would like to know how the JSON data can be de-serialized in my service?
Create classes and attributes that copy the structure of json data and use this framework for serialization and deserilazation:
Json Framework
Classes can be generated here:
Json to classes

I have a simple Spring boot project that uses controller mappings to get hard coded information from a class in my project.
For example, if I run the request : localhost:8080/topics, A JSON response is returned with the list of Topic Objects that i have previously created
I want to take this one step further and have a class who's variables are populated by calling this API and parsing the response : https://www.alphavantage.co/query?function=TIME_SERIES_INTRADAY&symbol=MSFT&interval=1min&apikey=demo
I believe this can be done in Java by creating a HTTP connection and reading the data from an input stream, but is the an easier way of doing this with spring boot? Im not fully sure of the name of this procedure hence Im having trouble finding solutions online
Since you are using Spring Boot, making use of Spring's RestTemplate makes sense. It comes with several message converters out of the box, and uses Jackson by default for json content.
Spring has published a good Getting Started page for consuming RESTful web services.
However, the json content returned by that services doesn't look like it will map well to a Java object, so you may have to deserialize it to a HashMap to get to the data you want.
I did an attempt to create something like this.

The idea is to register controller interfaces. Each of the interfaces are mapped to some URL. For the interfaces a dynamic proxy are generated (if the implementations are not available locally). So developer just call controller's interface method. The method is invoked for dynamically generated proxy. The proxy uses RestTemplate to call remote URL. It sends and receive JSON and deserializes the returned JSOn to POJO objects returned from the controller.
You need to declare contract - controller interfaces plus DTO to exchange data as well as mapping to understand which URL should be called for each controller.
A 3rd party will be posting JSON data to my MVC application, and because the format of the JSON will vary depending on what kind of data is sent, I cannot create a single ViewModel representation of the JSON data and make that my argument.
I need to be able to structure my Action method to handle any format of JSON sent ... and the question is, how?
I have developed an ASP.NET WEB API that generates JSON data to be consumed by some other party. Now I have received a request for adding some extra data in each JSON response about the version of the WEB API.
Is there a simple way to extend the built-in JSON formatter so it will auto-append/prepend some fixed JSON properties whenever it formats some data-model or a collection of some data-model?
Thanks for any good advice :-)
Hi I am new to Java and not sure how to proceed (kindly ignore any typos or my language). Can somebody help me out (just the Idea/how to proceed, dont need any sample code). I am trying to create a Restful Json webservice (using Spring MVC).
The webservice that I am trying to create is kind of a wrapper for an existing XML based restful webservice.
The Idea is to have one common platform, since all other existing services are exposed as as JSON services.
My job is to fetch the XML transform it into a Json, but the tricky part is The Json schema is a superset of the XML schema (I mean it contains more elements that get filled with some default values).
Please let me know if you need more info.
Thanks in advance.
One way to do it would be to use Jaxb to transform the the incoming XML to Java Objects. Build your Jaxb objects in a way that it contains all the elements, the one with default values and the elements in the incoming XML.
Ones the XMl is converted into Jaxb you can use org.springframework.http.converter.json.MappingJacksonHttpMessageConverter message converter to convert your Jaxb object to Json string.
I am using Spring 3.0 and ExtJS. I have been trying to send a Map object from my controller to jsp. When I putting a pojo in HashMap and sending that HashMap to view.
From controller it is returning a Map but in ExtJS it is not able to read the response and gives below error.
HTTP Error code: 406
message
description The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers ().
Can anyone tell that how this can be resolved?
I dont think you can just shove any POJO into a map and return it via an HttpResponse. That's not how JSON works.
In order to send JSON from Java, you have to do the equivalent of serializing it using a JSON API (or roll your own). FlexJSON is one I use, as it ships in Spring Roo and is pretty easy.
