Get Json Data on JSP Using JSTL from spring model

In my spring controller, I have created a json : 

{
    "productsData": [
        {
            "code": "0100",
            "name": "Shirt",
            "summary": "Shirt for males"
        },
        {
            "code": "0101",
            "name": " Shirt 1",
            "summary": "Shirt for males"
        },
        {
            "code": "0102",
            "name": "Shirt 2",
            "summary": "Shirt for males"
        }
    ]
}

And added this json to model attribute as : 

model.addAttribute("productsJson", responseDetailsJson.toString());

When I am getting values from json on jsp as :

<c:if test="${not empty productsJson}">
<c:out value="${productsJson.productsData}"></c:out>
<c:forEach var="product" items="${productsJson.productsData}">
</c:forEach>

The exception is :-

${productsJson.productsData}' Property 'productsData' not found on type java.lang.String

The error is produced because you are trying to use productsData from an String. If you want to use this property you shouldn't use toString method in the controller.

Even if you use productsJson.productsData, I don't think is the correct way to call it. Most likely you should use productsJson['productsData']. This is because productsJson is a Map not an Object
