It should show a loading gif and do a ajax call to the spring mvc controller and return the result "ok" to the caller. 它应该显示一个加载的gif并对spring mvc控制器进行ajax调用，并将结果“确定”返回给调用者。 Could anyone give a sample code or some idea on implementing it ? 任何人都可以给出示例代码或实现示例的想法吗？

You have to make 2 controllers. 您必须制作2个控制器。

@Controller will be responsible for returning the page with loading gif (it can be Thymeleaf, JSP, or whatever), that HTML "view" returned by MVC @Controller will contain JavaScript with your AJAX implementation (jQuery, AngularJS, or whatever), that will make an AJAX call to your @RestController , requesting JSON/XML data (the URL has to be different eg "/myproject/api"). @Controller将负责返回加载了gif（可以是Thymeleaf，JSP或其他任何东西）的页面，由MVC @Controller返回的HTML“视图”将包含具有AJAX实现的JavaScript（jQuery，AngularJS或其他任何东西），这将对您的@RestController进行AJAX调用，以请求JSON / XML数据（URL必须不同，例如“ / myproject / api”）。

Then on your success method you will replace the loading GIF with your data from @RestController (the result "ok"). 然后，在成功方法上，您将用@RestController的数据替换正在加载的GIF（结果为“确定”）。
