如何显示控制器返回的带有angularjs的jsp页面

<script src="https://cdn.jsdelivr.net/angularjs/1.7.9/angular.min.js"></script>

<script>
    var app = angular.module('myApp', []);
    app.controller('myCtrl', function($scope) {
        $scope.message = "Hello, World!";
    });
</script>

<div ng-app="myApp" ng-controller="myCtrl">
    {{ message }}
</div>

@WebServlet("/example")
public class ExampleServlet extends HttpServlet {
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String message = "Hello, World!"; // 控制器返回的数据
        request.setAttribute("message", message);
        request.getRequestDispatcher("example.jsp").forward(request, response);
    }
}

@RequestMapping("/example")
public String example(Model model) {
    String message = "Hello, World!"; // 控制器返回的数据
    model.addAttribute("message", message);
    return "example";
}
