public class DefaultHttpErrorHandler extends java.lang.Object implements HttpErrorHandler
This class is intended to be extended to allow reusing Play's default error handling functionality.
The "play.editor" configuration setting is used here to give a link back to the source code when set and development mode is on.

public java.util.concurrent.CompletionStage<Result> onClientError(Http.RequestHeader request, int statusCode, java.lang.String message)
The base implementation calls onBadRequest, onForbidden, onNotFound, or onOtherClientError depending on the HTTP status code.
onClientError in interface HttpErrorHandlerrequest - The request that caused the client error.statusCode - The error status code. Must be greater or equal to 400, and less than 500.message - The error message.protected java.util.concurrent.CompletionStage<Result> onBadRequest(Http.RequestHeader request, java.lang.String message)
Returns Results.badRequest (400) with the included template from views.html.defaultpages.badRequest as the content.
request - The request that was bad.message - The error message.protected java.util.concurrent.CompletionStage<Result> onForbidden(Http.RequestHeader request, java.lang.String message)
Returns Results.forbidden (401) with the included template from views.html.defaultpages.unauthorized as the content.
request - The forbidden request.message - The error message.protected java.util.concurrent.CompletionStage<Result> onNotFound(Http.RequestHeader request, java.lang.String message)
If the environment's mode is production, then returns Results.notFound (404) with the included template from `views.html.defaultpages.notFound` as the content.
Otherwise, Results.notFound (404) is rendered with views.html.defaultpages.devNotFound template.
request - The request that no handler was found to handle.message - A message, which is not used by the default implementation.protected java.util.concurrent.CompletionStage<Result> onOtherClientError(Http.RequestHeader request, int statusCode, java.lang.String message)
The base implementation uses views.html.defaultpages.badRequest template with the
given status.
request - The request that caused the client error.statusCode - The error status code. Must be greater or equal to 400, and less than 500.message - The error message.public java.util.concurrent.CompletionStage<Result> onServerError(Http.RequestHeader request, java.lang.Throwable exception)
By default, the implementation of this method delegates to [[onProdServerError()]] when in prod mode, and [[onDevServerError()]] in dev mode. It is recommended, if you want Play's debug info on the error page in dev mode, that you override [[onProdServerError()]] instead of this method.
onServerError in interface HttpErrorHandlerrequest - The request that triggered the server error.exception - The server error.protected void logServerError(Http.RequestHeader request, play.api.UsefulException usefulException)
The base implementation uses a SLF4J Logger. If a special annotation is desired for internal server errors, you may want to use SLF4J directly with the Marker API to distinguish server errors from application errors.
This can also be overridden to add additional logging information, eg. the id of the authenticated user.
request - The request that triggered the server error.usefulException - The server error.protected final play.api.UsefulException throwableToUsefulException(java.lang.Throwable throwable)
This will generate an id for the exception, and in dev mode, will load the source code for the code that threw the exception, making it possible to report on the location that the exception was thrown from.
protected java.util.concurrent.CompletionStage<Result> onDevServerError(Http.RequestHeader request, play.api.UsefulException exception)
The base implementation returns Results.internalServerError with the content of
views.html.defaultpages.devError.
request - The request that triggered the error.exception - The exception.protected java.util.concurrent.CompletionStage<Result> onProdServerError(Http.RequestHeader request, play.api.UsefulException exception)
The base implementation returns Results.internalServerError with the content of
views.html.defaultpages.error template.
Override this rather than [[onServerError()]] if you don't want to change Play's debug output when logging errors in dev mode.
request - The request that triggered the error.exception - The exception.
