Using Eclipse with Play Framework 2.0

问题

I am new to Framework 2.0. In Play 1.0, after you Eclipsify your project, you have have a *.launch file that you can use to launch your project.

After you eclipsify in Play 2.0, you don't seem to have anything similar. Is there a way to control your launching and to debug Play 2.0, using Eclipse?

A similar question: Debug Playframework 2.0 in Eclipse

The answer to that question did not have specific enough instructions for me to know how to follow.

回答1:

Question 1:

After you have eclipsified, open Eclipse and choose File -> Import... -> Existing Projects into Workspace. A dialog will open, choose your Play Framework 2.0 project folder and click Finish.

Question 2:

1. Start your Play Framework application using play debug run. You will see something like this:

   Listening for transport dt_socket at address: 9999 ...

2. In Eclipse, right-click on your project in Project Explorer and choose Debug As -> Debug Configurations....

3. A new dialog called Debug Configurations will open. Double-click on Remote Java Application and a new window will appear on the right side. Change the Connection properties so that the point to host localhost and port 9999. Confirm by clicking the Debug button.

4. Put a breakpoint in your Application in Eclipse.

5. Try your application as normal in a web-browser. If it hits a breakpoint then Eclipse will be brought as frontmost and let you debug.
