播放框架：路由中断

Question

I am having some issues with the Play framework. It won't compile anymore, giving the following error:

java: cannot find symbol
  symbol:   variable debug
  location: class controllers.Application

Indeed this line in Apllication.java is underlined in red in IDEA, but as far as I remember that has always been the case:

I do have a debug.scala.html file under views. If I change the above return statement to return ok(); everything compiles fine, but that of course removes all functionality.

PS: The fact that that IDEA thinks that there are errors in the Play code, even when there are none and it all compiles fine, makes debugging somewhat difficult, I find. (As in screenshot above.) Is there a fix for this?

Answer 1

Idea tries to optimize imports by replacing wildcard imports with dedicated, so you can easily add this import manually:

import views.html.debug;

TIP: On the other hand try to DO NOT name your view as debug , info etc. - Play's Logger has such methods so if you will write imports carelessly you can accidentally use it in wrong place, so maybe just better call these views like debugView.scala.html ?

Answer 2

发现错误：之前，我做了一些重构，并且IDEA决定从文件中删除以下导入，因为它认为该文件未使用：

import views.html.*;
