问题 Is it a way to render a pure html file with play framework version 2? I don't want to put it in public/ folder because later on there will be some dynamic information added to it. 回答1: Here is my solution: in routes: I do some configurations as following. GET /hello.html controllers.Assets.at(path="/public/html", file="hello.html") GET /public/javascripts/jquery-1.9.0.min.js controllers.Assets.at(path="/public/javascripts", file="jquery-1.9.0.min.js") GET /public/stylesheets/bootstrap.css

Serializing a Scala List to JSON in Play2

由 冷暖自知 提交于 2020-01-28 04:30:25
问题 I am trying to deserialize a list of Scala objects to a JSON map in Play2 - a pretty trivial use case with JSON, I'd say. My JSON output would be something along the lines of: { "users": [ { "name": "Example 1", "age": 20 }, { "name": "Example 2", "age": 42 } ] } To achieve this I am looking at the Play2's JSON documentation titled "The Play JSON library" . To me their examples are pretty trivial, and I've confirmed that they work for me. Hence, I am able to deserialize a single User object

问题 I'm currently working on a web app with the play2 framework. Most of the time everything works fine. However when I decide to rebuild the project I get the error: "type HomeController is not a member of package controllers". I've done some research on the web and encountered discussions and topics about this error. However, on all of them this seems to be the answer: "Play 2.4, by default, generates a dependency injected router, unlike previously, when it used a static router. You have two

问题 In Play, when overloading controller methods, those individual methods cant be routed more than once cause the complier doesn't like it. Is there a possible way to get around this?
