Guice configuration errors: Could not find suitable constructor in controllers #36

Open mehayden opened 10 years ago

mehayden commented 10 years ago

I am trying to define a custom REST controller as per custom-rest-controllers.md. It compiles and runs the list method correctly, but then it gets an exception, seemingly to do with dynamic controller routes, although the routes are not defined with '@'. Here is the error and stack trace:

com.google.inject.ConfigurationException: Guice configuration errors:

1) Could not find a suitable constructor in controllers.LinkRestController. Clas ses must have either one (and only one) constructor annotated with @Inject or a zero-argument constructor that is not private. at controllers.LinkRestController.class(LinkRestController.java:21) while locating controllers.LinkRestController

Does LinkRestController have a zero-argument public constructor? Or one with @Inject annotation?

This seems to be similar to #42 which is fixed. Please try again with the latest snapshot version and tell me if you still experience the same problem. Otherwise we may close this bug.

Sorry, I'm no longer working on this app and have no way to verify, so close if you like.

I have the same problem. I can not solve it. Please help me. I am trying to update play framework 2.3.10 to 2.4.1 and got this error.
