Attach debugger (using eclipse) to play framework failed
提问by user2512057
I am using Scala to write a web on top of Play framework with eclipse IDE. I am trying to debug my app but hit debug attach failure. I tried to switch using Java instead of Scala,but I got same error. This is what I do.
我正在使用 Scala 在带有 Eclipse IDE 的 Play 框架之上编写一个 Web。我正在尝试调试我的应用程序，但遇到调试附加失败。我尝试使用 Java 而不是 Scala 进行切换，但我遇到了同样的错误。这就是我所做的。
- Create a project and run
play clean compile - run
play debug run - in Eclipse, set 'debug configration' ->remote java application -> host: localhost, port:9999 and common: debug
- in browser type in URL and enter: localhost:9999. Then get the following failure in play framework command line:
Debugger failed to attach: handshake failed - received
>GET / HTTP/1.1< - expected >JDWP-Handshake<
- 创建项目并运行
play clean compile - 跑
play debug run - 在 Eclipse 中，设置“调试配置” -> 远程 Java 应用程序 -> 主机：本地主机，端口：9999 和通用：调试
- 在浏览器中输入 URL 并输入：localhost:9999。然后在播放框架命令行中得到以下失败：Debugger failed to attach:handshake failed - received
>GET / HTTP/1.1< - expected >JDWP-Handshake<
Any idea what is wrong?
知道出了什么问题吗？

localhost:9999is what Eclipse is going to use to communicate with your application. On your browser, you still access your application on localhost:9000(default) or however you would access your application had you just done play run.
localhost:9999是 Eclipse 将用来与您的应用程序通信的东西。在您的浏览器上，您仍然可以在localhost:9000（默认）上访问您的应用程序，或者您将访问您刚刚完成的应用程序play run。
Basically, you've configured your debugging correctly in Eclipse.
基本上，您已经在 Eclipse 中正确配置了调试。
- Now, with your configuration selected from the Debug Configuration, click Debug(or selected your configuration from the Debug Astoolbar button). Eclipse will attach to
localhost:9999. - Browse to
localhost:9000like you normally would to access your application. - That's it. Eclipse will pause on any breakpoints you have set, etc.
- 现在，从Debug Configuration 中选择您的配置后，单击Debug（或从Debug As工具栏按钮中选择您的配置）。Eclipse 将附加到
localhost:9999. - 浏览
localhost:9000您通常会访问您的应用程序。 - 就是这样。Eclipse 将在您设置的任何断点等处暂停。
