Is there a way to generate json data from json schema with multi source json data?

I am currently working with a project to implement data fusion / data integration. Now I can find the technology to get json schemas from json data. But how could I integrate different json attributes into the target json schema. My final target is to implement the json data fusion by configuration on a web page. Is there any solution or any open source implementation I could take referrence? Thank you so much.
Please allow me to explain it more clearly. I could define a target json schema, and its attributes should be filled by other json data's attributes (the json may come from multi source).

How to write the output from DB to a JSON file using Spring batch?

I am new to spring batch and there is a requirement for me to read the data from DB and write in to JSON format. whats the best way to do this ? Any api's are there? or we need to write custom writer ? or i need to user JSON libraries such as GSON or JACKSON ? Please guide me...
To read data from a relational database, you can use one of the database readers. You can find an example in the spring-batch-samples repository.
To write JSON data, Spring Batch 4.1.0.RC1 provides the JsonFileItemWriter that allows you to write JSON data to a file. It collaborates with a JsonObjectMarshaller to marshal an object to JSON format. Spring Batch provides support for both Gson and Jackson libraries (you need to have the one you want to use in the classpath). You can find more details here.
Hope this helps.
You do not need GSON or Jackson Libraries if you DB support JSON.
Example : In SQL Server there is an option to get data out of DB as JSON String instead of resultset.
Reference - https://learn.microsoft.com/en-us/sql/relational-databases/json/format-query-results-as-json-with-for-json-sql-server?view=sql-server-2017
https://learn.microsoft.com/en-us/sql/relational-databases/json/format-nested-json-output-with-path-mode-sql-server?view=sql-server-2017
Example - select (select * from tableName for json path) as jsonString;
This will already give you output in JsonString which you can write to a file.

How to parse JSON response in filemaker script

Anyway I would like to parse this json response in filemaker. How can i accomplish that?

There are several plugins that can help you handle JSON: BaseElements, bBox, MBS and probably others.
The FileMaker Community discussion on Script from FM to pull and parse a JSON file has links to these, as well as some Custom Functions for native parsing.

Suggestion required: RESTFUl webservice transform xml to Json

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.
