Extracting the elements from a JSON string array

In my web application, I am managing a cart array consisting of different products. Each product within the array has various specifications such as URL, name, price, quantity, and total price, all stored within their own arrays.

This essentially creates an array of arrays that I now need to save to a database.

To achieve this, I must first extract these arrays in a Java class before proceeding to store them in the database.

How do I go about transferring this array into the database?

Here is an example of my JSON-formatted array:

{"products":[{"productURL":"images/product/a.jpg","productName":"Headfones 1","productPrice":"234","productQuantity":"2","productTotal":"468"},
{"productURL":"images/product/b.jpg","productName":"Headfones 2","productPrice":"234","productQuantity":"3","productTotal":"702"},
{"productURL":"images/product/d.jpg","productName":"Headfones 4","productPrice":"234","productQuantity":"1","productTotal":"234"},
{"productURL":"images/product/d.jpg","productName":"Headfones 4","productPrice":"234","productQuantity":"6","productTotal":"1404"}]}

Are there any specific libraries available for parsing JSON data?

Answer №1

Transfer the JavaScript array in JSON format over to the server, then proceed to decode the JSON on the server and transform it into a Java array. My recommendation is to utilize the Jackson JSON parser. Below is an operational demonstration:

    String JSON = "[[\"images/product/a.jpg\",\"Headfones 1\",\"234\",3,702],"
            + "[\"images/product/b.jpg\",\"Headfones 2\",\"234\",4,936],"
            + "[\"images/product/c.jpg\",\"Headfones 3\",\"234\",5,1170]]";
    String[][] products = new ObjectMapper().readValue(
            JSON, 
            new TypeReference<String[][]>() {});

Having obtained the products array, you are now equipped to begin inputting the data into the database.
