附加调试器（使用eclipse）来播放框架失败 [英] Attach debugger (using eclipse) to play framework failed

问题描述

我正在使用Scala在eclipse IDE的Play框架之上编写一个网页。我试图调试我的应用程序，但调试附件失败。我试图使用Java而不是Scala进行切换，但是我遇到了同样的错误。这就是我所做的。

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.

1. 创建项目并运行播放清洁编译
$ b $在Eclipse中运行播放调试运行

2. ，设置'debug configration' - >远程java应用程序 - > host：localhost ，端口：9999和common：debug


3. 在浏览器类型的URL中输入：localhost：9999。然后在play框架命令行中得到以下失败：
   调试器无法附加：握手失败 - 已收到> GET / HTTP / 1.1< - 预期> JDWP-Handshake

1. Create a project and run play clean compile
2. run play debug run
3. in Eclipse, set 'debug configration' ->remote java application -> host: localhost, port:9999 and common: debug
4. 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<

任何想法有什么问题？

Any idea what is wrong?

推荐答案

localhost：9999 是Eclipse将用于沟通与您的应用程序。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，但是如果您刚刚完成 code>。

localhost:9999 is 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.

基本上，您已经在Eclipse中正确配置了调试。

Basically, you've configured your debugging correctly in Eclipse.

1. 现在，从调试配置中选择您的配置，点击调试（或从调试方式工具栏按钮中选择您的配置）。 Eclipse将附加到 localhost：9999 。


2. 浏览到 localhost：9000 像你通常会访问您的应用程序。


3. 就是这样。 Eclipse将暂停您设置的任何断点等。

1. Now, with your configuration selected from the Debug Configuration, click Debug (or selected your configuration from the Debug As toolbar button). Eclipse will attach to localhost:9999.
2. Browse to localhost:9000 like you normally would to access your application.
3. That's it. Eclipse will pause on any breakpoints you have set, etc.
