Why use @Singleton over Scala's object in Play Framework?

由 梦想的初衷 提交于 2019-12-30 01:37:17
问题 I have been using Play! Framework for Scala for nearly a year now. I am currently using version 2.5.x. I am aware of the evolution of controllers in Play and how developers have been forced away from static object routes. I am also aware of the Guice usage in play. If you download activator and run: activator new my-test-app play-scala Activator will produce a template project for you. My question is specifically around this file of that template. my-test-app/app/services/Counter.scala

Practical advice on using Jersey and Guice for RESTful service

由 牧云@^-^@ 提交于 2019-12-29 10:06:14
问题 From what I can find online, the state of the art for Guice + Jersey integration has stagnated since 2008 when it appears both teams reached an impasse. The crux of the issue is that JAX-RS annotations perform field and method injection and this doesn't play nicely with Guice's own dependency injection. A few examples which I've found don't go far enough to elucidate: Iqbalyusuf's post on Jersey + Guice on Google App Engine Java suffers from a lot of boilerplate (manually getting and calling

问题 I have successfully created a Guice binding annotation to inject single threaded java.util.concurrent.ExecutorService instances into a constructor. here is an example usage: public class ContainsSingleThreadedExecutorService { private final ExecutorService executorService; @Inject public ContainsSingleThreadedExecutorService(@SingleThreaded ExecutorService executorService) { this.executorService = executorService; } } I now want to create a similar annotation for multi-threaded executors,

Appengine with Google Cloud Endpoints and Guice

由 ＊爱你＆永不变心＊ 提交于 2019-12-28 12:04:19
问题 So i want to use Guice in Appengine with Cloud Endpoints to inject my services, or daos - pretty common I guess, but I found no tutorial for this. Official Guice for Appengine documentation seems to be here: https://github.com/google/guice/wiki/GoogleAppEngine When configuring Guice you set up the com.google.inject.servlet.GuiceFilter to intercept every request "/*". And at some point you must initialize the modules. Like the documentation says a good place to do that is a

Injecting services into Scala Akka Actors with Google Guice

由 六眼飞鱼酱① 提交于 2019-12-25 14:25:24
问题 I have a couple of services that I want to inject into akka actors. There are three different types of actors I am working with, and each type will use different services. Currently I just have a module, instantiate an injector inside of the actor, and do the binding inside of each Crow. The issue is that for each other, they receive a new instance of the service. I did a little bit of reading and found http://www.typesafe.com/activator/template/activator-akka-scala-guice but the

Java: Can't get a working ServiceLoader

由 我怕爱的太早我们不能终老 提交于 2019-12-25 12:46:05
问题 I am very new to Java (coming from C# .NET background). Trying to create an "expansion/IoC" style architecture via a combination of Google Guice and ServiceLoader, but can't seem to get the ServiceLoader part working running Java 1.7.0_75 and IntelliJ IDEA 14. I have a module within my project which is effectively a base class library called ViProJ.Bcl that contains an interface called com.vipro.bcl.SimplePluginLoader. I have another module called ViProJ.TestModules which contains a single

Why is Eclipse not able to resolve Guice import in Play 2.2.x application?

问题 I'm trying to use Google Guice Injections in my Play 2.2.2 project. My build.sbt file contains this: libraryDependencies ++= Seq( javaJdbc, javaEbean, cache, "com.google.inject" % "guice" % "4.0-beta", "ws.securesocial" %% "securesocial" % "2.1.4", "postgresql" % "postgresql" % "9.1-901-1.jdbc4" ) When running play dependencies , I can see that the guice dependency is being resolved correctly. However, when trying to make the import com.google.inject.* statement it seems that the library is
