playframework

问题 I am experiencing an issue in Play 2.5.8 (Java) where database related service endpoints starts timing out after a few days even though the server CPU & memory usage seems fine. Endpoints that does not access the DB continue to work perfectly. The application runs on a t2.medium EC2 instance with a t2.medium MySQL RDS, both in the same availability zone. Most HTTP calls do lookups/updates to the database with around 8-12 requests per second, and there are also ±800 WebSocket connections

问题 I am new to Scala and Play! programming but have a reasonable amount of experience with webapps in Django, and plenty of general programming experience. I have been doing some exercises of my own to try to improve my understanding of Play! and this behaviour has me totally stumped. This is a follow-up question to the more general one here: Trying to understand Scala enumerator/iteratees I am trying to query a database, using Enumerators, Iteratees and Futures.

It looks something like this: \app\Game\Views \app\Game\Controllers \app\Game\Services \app\Game\Repositories \app\Players\Views \app\Players\Controllers \app\Common\Views \app\Common

问题 My play application has an endpoint for receiving webhooks from Stripe. In order to verify the webhooks, the request body needs to be compared against a signature and a signing key. This requires that I have access to the raw request body, as sent. However, it seems that Play alters the request body, and I can't get access to the raw contents. This causes the computed signature to change, and the verification fails. More info: https://stackoverflow.com/a/43894244/49153 Here's my code:

问题 I have a job that runs on the hour. I would like to either call a Controller's Action method like this: public class MyJob extends Job { @Override public void doJob() throws Exception { MyController.someActionMethod(); } } or call a URL directly. Any ideas if this is possible from within a Job? If I call a Controller's action method directly, I get this: NullPointerException occured : null play.exceptions.JavaExecutionException at play.jobs.Job.call(Job.java:155) at java.util.concurrent

问题 I am trying to call arbitrary controller actions, specified by a String , from a Job subclass. I have tried the accepted answer to this question, but found that it doesn't work for me... WS.url("http://www.yahoo.com/").get(); works, but WS.url("http://localhost/foo/bar").get() blocks and eventually times out after 60 seconds. I have also tried increasing the play.pool value in application.conf , as recommended in this answer, but it made no difference. Here is my code: application.conf: #

问题 What is the recommended pattern for managing Mondrian database connections? I am using Mondrian as a library in a Scala/Play Framework web application. For example: var connection try { connection = DriverManager.getConnection(connection_string).unwrap(classOf[OlapConnection]) val result = connection.createStatement.executeOlapQuery(mdx) // ... use the result ... } finally { if (connection) connection.close } Is calling close in a finally block the right approach?
