如何从Play Framework 2.5.X调用Java方法

Question

1. 我有一个JavaScript文件morris.js ，我必须调用一些Java方法来检索map或list结果。 我不能使用反向路由或控制器方法，因为我必须在控制器内返回Result类型。

   我该如何实现？

   预期结果的示例：

    $.ajax(some method) .done(some treatment) .fail(console.log('not ok')); // data stolen from http://howmanyleft.co.uk/vehicle/jaguar_'e'_type var tax_data = [ {"period": "2013", "licensed": 400, "sorned": 550}, {"period": "2012", "licensed": 450, "sorned": 400}, {"period": "2011", "licensed": 350, "sorned": 550}, {"period": "2010", "licensed": 500, "sorned": 700}, {"period": "2009", "licensed": 250, "sorned": 380}, {"period": "2008", "licensed": 350, "sorned": 240}, {"period": "2007", "licensed": 180, "sorned": 300}, {"period": "2006", "licensed": 300, "sorned": 250}, {"period": "2005", "licensed": 200, "sorned": 150} ]; 

2. 我有一个在控制器中带有参数的方法。 如何将其添加到JavaScript路由器中：

    public Result getYearUploadedVideos(Long userId){ // ... } 

   我的路由器：

    public Result jsRoutes() { return ok(play.routing.JavaScriptReverseRouter.create("jsRoutes", routes.javascript.Signup.forgotPassword(), routes.javascript.AdminManagement.contact(), routes.javascript.ProfilManagement.view(), routes.javascript.DashboardManagement.getYearUploadedVideos())) .as("text/javascript"); } 

...但是它不起作用。 有什么帮助吗？

Answer 1

其实很容易：

public Result jsRoutes() {
    return ok(
            play.routing.JavaScriptReverseRouter.create("jsRoutes",
                    routes.javascript.Signup.forgotPassword(),
                    routes.javascript.DashboardManagement.getSmartCasterSharedDonutStatDataJson(),
                    routes.javascript.DashboardManagement.getSmartCasterActionStatDataJson(),
                    routes.javascript.DashboardManagement.getUploadedPublishedVideoStatDataJson(),
                    routes.javascript.DashboardManagement.getVideoSharedDonutStatDataJson(),
                    routes.javascript.DashboardManagement.getVideoActionStatDataJson()))
            .as("text/javascript");

}

然后 ：

$.ajax(jsRoutes.controllers.DashboardManagement.getVideoSharedDonutStatDataJson(id))
    .done(function(donut){ 
        console.log(JSON.stringify(donut));
...});

就是这样，我们没有在反向JS路由中配置ID
