Playframework - subpackaged controllers and routing issues

 原文  2017-07-12 09:24:27  2   1    java/ scala/ intellij-idea/ playframework/ sbt

Question

System Details:

  • Arch Linux: 4.11.7-1-ARCH x64
  • Oracle Java JDK: 1.8.0_131
  • IntelliJ Scala plugin: 2017.1.19 (latest)
  • SBT: 0.13.13 (latest)
  • IntelliJ IDEA Ultimate 2017.1.4
  • Play Framework: 2.6.1

Intro

note: I am new to play framework

I am using the provided "play-starter" project, and with this I have created a controller that routes to various pages. This worked by using no subpackages.

Directory structure: {root}/app/controllers/MyController

MyController.index() was displayed with the routing path: 

GET     /                        controllers.MyController.index

this displayed as expected, also a POST method I created functioned as expected.

Problem:

I attempted creating subpackages to start my project, but received errors at every turn (details below).

Browsing the routing documentation yielded no solution (for me). I searched for similar issues, found here is a very similar issue, but the answer does not solve my problem.

A blog seemed to address the issue, which I attempted without success.

Problem details:

I created a subpackage User . Within this subpackage, I have one controller AccountController

AccountController has several functions, I'll use doLogin() for the purposes of this question

Directory structure: {root}/app/controllers/User/AccountController

Suggested Solution:

All solutions point to the same code (which results in various errors)

Each package has its own routes file. In my case, I should use controllers.User.routes followed by the controller name and function for the routes file

eg 

POST       /user/login        controllers.User.routes.AccountController.doLogin()

where the directory layout is controllers/User/AccountController and using using this for display purposes in a view ( found here ) I use 

<form action="@controllers.User.routes.AccountController.doLogin()" method="post">

BUT this does not work.

Extra Info:

package controllers.User;

Seems to have been some bug, since redoing what I did any previous "tests" to get it working, has proved to resolve the issue.

A formal solution for Play 2.6.1 project having a sub package and requiring routing to it:

Subpackage name: User Subpackage Controller: AccountController

Project App Directory Structure: 

app/
      controllers/ (provided)
      filters/ (provided)
      models/ 
      services/ (provided)
      views/  (provided)

Controllers Directory 

controllers/
          User/ (sub package)
                AccountController.java
          HomeController.java (provided)

Account controller contains methods:

  • index()
  • register()
  • doRegister()

Views Directory 

views/
          User/
                Account/
                     index.scala.html
                     register.scala.html
          index.scala.html (provided)

Note: try to keep the same directory structure (see User/Account/{controller function name} )

Routing file entry conf/routes : 

GET        /user                 controllers.User.AccountController.index
GET        /user/register        controllers.User.AccountController.register()

#disable this (below) and you will receive a 403 forbidden error, the CRSF filter is used for cross site scripting prevention, use for authentication. 
#You can apply this autentication: see https://stackoverflow.com/questions/45017920/post-method-rendering-403-forbidden-page-instead-of-executing-post-method-code

#+ nocsrf
POST       /user/register        controllers.User.AccountController.doRegister()

Hopes this helps!
