I'm newbie on spring boot. I'm already implement some request mappings with successfully output in json.
localhost:8080/gJson
{
ad: "Windows 10",
mimari: "amd64",
versiyon: "10.0",
diskSize: 918,
freediskSize: 614,
cores: 8,
usablediskSize: 614
}
And My Controller here
@EnableAutoConfiguration
@Controller
public class GreetingController {
@RequestMapping(value = "/gJson", produces=MediaType.APPLICATION_JSON_VALUE)
public @ResponseBody MyPojo gJson(){
...
}
}
And now, I need ... example when I'm going to this link > localhost:8080/GetInfo getting json from localhost:8080/gJson but every "X" seconds.
Thanks For Helping.

How is /GetInfo being served? Is it just a standard HTML page? If so you can code a Javascript element that has a setInterval() to make an XMLHttpRequest to the /gJson endpoint. There are a number of other ways to do it depending on what libraries you want to use to have browser to server communications.
* Update * Sample project: https://github.com/ShawnTuatara/stackoverflow-38890600
Main aspect that allows the refresh is the HTML page at src/main/resources/static/GetInfo.html
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>GetInfo</title>
<script
src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
</head>
<body>
</body>
<script type="text/javascript">
$(function() {
window.setInterval(function() {
$.ajax({
url : "/gJson"
}).done(function(data, status, jqXHR) {
$("body").text(jqXHR.responseText);
});
}, 10000);
});
</script>
</html>
The controller is straightforward as outlined in the question.
@EnableAutoConfiguration
@RestController
public class GreetingController {
@GetMapping(value = "/gJson", produces = MediaType.APPLICATION_JSON_VALUE)
public MyPojo gJson() {
return new MyPojo("Windows 10", System.currentTimeMillis());
}
}
Finally the MyPojo is just a simple two field class.
public class MyPojo {
private String ad;
private long timestamp;
public MyPojo(String ad, long timestamp) {
this.ad = ad;
this.timestamp = timestamp;
}
public String getAd() {
return ad;
}
public void setAd(String ad) {
this.ad = ad;
}
public long getTimestamp() {
return timestamp;
}
public void setTimestamp(long timestamp) {
this.timestamp = timestamp;
}
}
I included the timestamp so that you can see the time refreshing every 10 seconds on the web page.
