Method Detail

beforeStart

public void beforeStart(Application app)

Deprecated.

Executed before any plugin - you can set-up your database schema here, for instance.

Parameters:

app - the bootstrapping application

onStart

public void onStart(Application app)

Deprecated.

Executed after all plugins, including the database set-up with Evolutions and the EBean wrapper. This is a good place to execute some of your application code to create entries, for instance.

Parameters:

app - the bootstrapped application

onStop

public void onStop(Application app)

Deprecated.

Executed when the application stops.

Parameters:

app - the application that is shutting down

onError

public java.util.concurrent.CompletionStage<Result> onError(Http.RequestHeader request,
                                                            java.lang.Throwable t)

Deprecated.

Called when an exception occurred. The default is to send the framework's default error page. This is achieved by returning null, so that the Scala engine handles the excepetion and shows an error page. By overriding this method one can provide an alternative error page.

Parameters:

request - header of the HTTP request being processed

t - is any throwable

Returns:

null as the default implementation

onRequest

public Action onRequest(Http.Request request,
                        java.lang.reflect.Method actionMethod)

Deprecated.

Call to create the root Action of a request for a Java application. The request and actionMethod values are passed for information.

Parameters:

request - The HTTP Request

actionMethod - The action method containing the user code for this Action.

Returns:

The default implementation returns a raw Action calling the method.

onRouteRequest

public play.api.mvc.Handler onRouteRequest(Http.RequestHeader request)

Deprecated.

Called when an HTTP request has been received. The default implementation (return null) means to use the application router to find the appropriate action By overriding this method one can provide an alternative routing mechanism. Please note, though, this API is very low level, useful for plugin/module authors only.

Parameters:

request - the HTTP request header as seen by the core framework (the body has not been parsed yet)

Returns:

an action to handle this request - if no action is returned, a 404 not found result will be sent to client

onHandlerNotFound

public java.util.concurrent.CompletionStage<Result> onHandlerNotFound(Http.RequestHeader request)

Deprecated.

Called when no action was found to serve a request. The default behavior is to render the framework's default 404 page. This is achieved by returning null, so that the Scala engine handles onHandlerNotFound. By overriding this method one can provide an alternative 404 page.

Parameters:

request - the HTTP request

Returns:

null in the default implementation, you can return your own custom Result in your Global class.

onBadRequest

public java.util.concurrent.CompletionStage<Result> onBadRequest(Http.RequestHeader request,
                                                                 java.lang.String error)

Deprecated.

Called when an action has been found, but the request parsing has failed. The default behavior is to render the framework's default 400 page. This is achieved by returning null, so that the Scala engine handles onBadRequest. By overriding this method one can provide an alternative 400 page.

Parameters:

request - the HTTP request

error - an arbitrary string describing the error

Returns:

null in the default implementation, you can return your own custom Result in your Global class.

filters

public <T extends play.api.mvc.EssentialFilter> java.lang.Class<T>[] filters()

Deprecated.

Get the filters that should be used to handle each request.

Type Parameters:

T - the filter type

Returns:
