Tips on transmitting JSON data from a Spring controller to JavaScript

Does anyone have experience with sending a JSON object from a spring controller to JavaScript and receiving it using AJAX? I would appreciate any guidance on how to accomplish this.

Answer №1

If you need to interact with a Spring rest service from javascript, there are several options available. You can go with traditional XMLHttpRequest, utilize jQuery Ajax, or leverage the modern Fetch API. The choice ultimately depends on your specific requirements, so explore each method further by checking out the provided links. Below is a simple example showcasing how to use jQuery Ajax.

var jqxhr = $.ajax({
    url: "/your-url",
    type: "GET",
    data: inputData,
    dataType: "json"
});

//Handle a successful call to the data service
jqxhr.done(function(data, textStatus, jqxhr) {
    // Your success code here
});

//Handle an unsuccessful call to the data service
jqxhr.fail(function(jqXHR, textStatus) {
    // Code to handle failure
});

jqxhr.always(function() {
    // Your additional code
});
