    Is there any way to maintain order while transforming JSON to XML. I have a Input JSON file. But when I convert it into XML, the order will be changed. I was searching solution from past 2 days. I tried in mule as well as in Java but it won’t work. This is the Input JSON data.
    {
    “status” : “success”,
    “response” : {
    “p_status_msg” : {
    “contact” : {
    “contactlist” : [{
    “address” : “90 Grove St., Newport ME 04953; United States of America”,
    “grp” : “ADDRESS”,
    “pidm” : “”,
    “type” : “Home (preferred)”
    }, {
    “address” : “[email protected]”,
    “grp” : “EMAIL”,
    “pidm” : “”,
    “type” : “Academy Email”
    }, {
    “address” : “[email protected]”,
    “grp” : “EMAIL”,
    “pidm” : “”,
    “type” : “Email”
    }, {
    “address” : “(207) 341-3018”,
    “grp” : “PHONE”,
    “pidm” : “”,
    “type” : “Cell Phone”
    }
    ],
    “contact” : {
    “studentid” : “P000020581”,
    “dateofbirth” : “07/07/1995”,
    “firstname” : “John”,
    “socialsecuritynumber” : “005961046”,
    “gender” : “M”,
    “middlename” : “Q.”,
    “lastname” : “Adams”
    }
    }
    }
    }
    }

    Please help me out. Thanks!!!

      Yes you can maintain the order.
      Once the program gives you have the output result, copy and paste it a notepad and then cut paste the data to bring it in correct order.

    Kishore Diyyana:

    For Spring Boot App to Ignore Case for JSON attributes names:

    Step 1: Make sure your POJO/Domain/Model class has constructor with respective parameters, remove any zero arg constructor. Step 2: Add Jackson lib as dependency Ex:

    com.fasterxml.jackson.module
    jackson-module-jaxb-annotations
    2.6.5

    Step 3: Enable in application.properties file as below spring.jackson.mapper.accept_case_insensitive_properties=true
