There are various ways you can call Spring rest service from javascript . You can choose pure javascript usingXMLHttpRequest , jQuery Ajax , Fetch etc. It really depends on you requirements. You can look at individual link for more details. Here is one simple example using jQuery Ajax .

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

});

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

//Handle an unsuccessful call to data service
jqxhr.fail(function(jqXHR, textStatus) {
    // your code to handle fail     

});
jqxhr.always(function () {
    //your code
}); 

});
