Java Play framework 2.2.1无法运行应用程序-“；“页面不存在”；

我已经尝试运行现有的play应用程序，它可以正确编译和运行（控制台中没有错误）

但是当我打开主页（

http://localhost:9000/

）：

页面不存在

显示消息

我还在调试日志中发现：

[application]-[ERROR]-[play akka.actor.default-dispatcher-12]-会话元素：品牌异常唯一，预期为0或1行，但得到[18]

有人能解释一下这个信息是什么意思吗

同样值得一提的是，应该仅在项目开始或其他情况下使用

播放运行

控制台输出：

问题在于应用程序配置，所以我刚刚将127.0.0.1:9000添加到数据库中，所有工作都正确无误。对我来说很奇怪，如果localhost与datapase中的用户没有关联，那么就会显示错误页面。但是有人写的。 感谢您的回复

它也可能与项目的cookies会话有关，请查看application.conf并查看cookies会话/flash配置、数据库配置等

回答另一个问题时，有时需要传递其他特定的配置文件，如

运行-Dconfig.resources=otherconfigfilename.conf

，或类似的应用程序密钥

运行-Dplay.http.secret.key=“fnglksjgajadljglaj”

但对于更简单的项目，sbt run会起作用

请提供更多细节。是默认播放还是您编写了代码/更改路线/等等<代码>播放运行延迟编译代码，这样只有在尝试访问时才能看到错误。使用

播放开始

进行制作。我正在使用播放2.2.1。我也没有改变任何事情。我刚从svn那里得到了这个项目，并试着运行它。该项目在linux服务器上正常工作，但我可以在本地pc（Windows 8.1）上运行它。从Pick开始尝试，我猜您的意思是签出现有项目，而不是默认项目。从我在日志中看到的是DB的用法，所以可能有一些与之相关的东西。（访问数据库或缺少的预期表/值）。。还有其他日志文件-如果它们包含您在控制台中看不到的日志，请签出
