简介
注意:我是玩框架的新手
我正在使用提供的“play-starter”项目,并通过该项目创建了一个路由到各个页面的 Controller 。这是通过不使用子包来实现的。
目录结构:{root}/app/controllers/MyController
MyController.index()
显示了路由路径:
GET / controllers.MyController.index
这按预期显示,我创建的 POST
方法也按预期运行。
问题:
我尝试创建子包来启动我的项目,但每次都会收到错误(详细信息如下)。
浏览routing documentation没有产生任何解决方案(对我来说)。我搜索了类似的问题,发现here是一个非常相似的问题,但答案并没有解决我的问题。
一个blog似乎解决了这个问题,我尝试过但没有成功。

问题详细信息:
我创建了一个子包User
。在这个子包中,我有一个 Controller AccountController
AccountController
有多个函数,我将使用 doLogin()
来解决此问题
目录结构:{root}/app/controllers/User/AccountController
建议的解决方案:
所有解决方案都指向相同的代码(这会导致各种错误)
每个包都有自己的路由文件。就我而言,我应该使用controllers.User.routes
,后跟路由文件的 Controller 名称和函数
例如
POST /user/login controllers.User.routes.AccountController.doLogin()
其中目录布局是controllers/User/AccountController
,并使用它在 View 中显示目的(found here)我使用
<form action="@controllers.User.routes.AccountController.doLogin()" method="post">
但是这不起作用。

最佳答案
似乎存在一些错误,因为重做我之前所做的任何“测试”以使其正常工作,已证明可以解决问题。
具有子包并需要路由到它的 Play 2.6.1
项目的正式解决方案:
子包名称:用户
子包 Controller :AccountController
项目应用程序目录结构:
app/
controllers/ (provided)
filters/ (provided)
models/
services/ (provided)
views/ (provided)
Controller 目录
controllers/
User/ (sub package)
AccountController.java
HomeController.java (provided)
帐户 Controller 包含方法:
- 索引()
- 注册()
- doRegister()
查看目录
views/
User/
Account/
index.scala.html
register.scala.html
index.scala.html (provided)
注意:尽量保持相同的目录结构(参见User/Account/{controller function name}
)
路由文件条目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()
希望这有帮助!
