[英]Playframework - subpackaged controllers and routing issues
系統詳情:
介紹
注意:我是新玩的框架
我正在使用提供的“ play-starter”項目,並以此創建了一個路由到各個頁面的控制器。 通過不使用任何子包來工作。
目錄結構: {root}/app/controllers/MyController
MyController.index()
與路由路徑一起顯示:
GET / controllers.MyController.index
這按預期顯示,我創建的POST
方法也按預期運行。
問題:
我嘗試創建子包來啟動我的項目,但是在任何時候都收到錯誤消息(詳細信息如下)。
瀏覽路由文檔沒有解決方案(對我來說)。 我搜索了類似的問題,發現這里是一個非常相似的問題,但是答案不能解決我的問題。
一個博客似乎解決了這個問題,但我沒有成功。
錯誤輸出:

問題詳細信息:
我創建了一個子包User
。 在這個子包中,我有一個控制器AccountController
AccountController
有幾個函數,出於這個問題的目的,我將使用doLogin()
目錄結構: {root}/app/controllers/User/AccountController
建議的解決方案:
所有解決方案都指向相同的代碼(這會導致各種錯誤)
每個程序包都有自己的路由文件。 就我而言,我應該使用controllers.User.routes
后跟路由文件的控制器名稱和功能
例如
POST /user/login controllers.User.routes.AccountController.doLogin()
我的目錄布局是controllers/User/AccountController
並用於在視圖中顯示此視圖( 在此處找到 )
<form action="@controllers.User.routes.AccountController.doLogin()" method="post">
但是這不起作用。
額外信息:
{root} / app / controllers / User / AccountController

似乎是一個錯誤,因為重做了我以前做過的所有“測試”以使其正常運行,事實證明已解決了該問題。
Play 2.6.1
項目的正式解決方案,具有子包並需要路由至該子包:
子軟件包名稱: User
軟件包控制器: AccountController
項目應用目錄結構:
app/
controllers/ (provided)
filters/ (provided)
models/
services/ (provided)
views/ (provided)
控制器目錄
controllers/
User/ (sub package)
AccountController.java
HomeController.java (provided)
帳戶控制器包含以下方法:
視圖目錄
views/
User/
Account/
index.scala.html
register.scala.html
index.scala.html (provided)
注意:嘗試保持相同的目錄結構(請參閱User/Account/{controller function name}
)
路由文件輸入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()
希望這會有所幫助!
