Kotlin – SpringBoot + Jquery JsonP for requests to cross domain

In the post, JavaSampleApproach will show you how to use JQuery JsonP Request to Kotlin SpringBoot server without worrying about cross-domain issues.

I. Technologies

• Kotlin 1.2 – Java 1.8 – Maven 3.6.1 – Spring Tool Suite – Version 3.9.0.RELEASE – Bootstrap – Spring Boot – 1.5.10.RELEASE

  II. Jquery JsonP and Kotlin SpringBoot

  JSONP is a solution to resolve cross-domain issues which uses script tag instead XMLHttpRequest object. With JQuery, we can use it as below:

$.ajax({
    type : "GET",
    url : "http://localhost:9000/api/customer/all",

    jsonp: "jsaJsonpCallback",
    
    // Tell jQuery that we're expecting JSON-P
    dataType: "jsonp",
    
    success: function(result){
        // do something here
    },
    error : function(e) {
        // do something here
    }
});
