[英]How to integrate Guice 2 into Wicket?
I want to use Guice 2 with Wicket 1.4. 我想在Wicket 1.4中使用Guice 2。 There is a "wicket-guice" package, which uses Guice 1. Can someone give me an example how to configure Wicket to use Guice 2 for injection (with Maven). 有一个使用“ Guice 1”的“ wicket-guice”软件包。有人可以给我一个示例,如何配置Wicket以使用Guice 2进行注入(与Maven一起使用)。
As you can see blow, I've found a solution, but I wonder, if it would be better to use Guice Servlets and register the whole Wicket Application as a ServletFilter with Guice. 如您所见,我找到了一个解决方案,但是我想知道,使用Guice Servlet并将整个Wicket应用程序注册为带有Guice的ServletFilter会更好。 But I think this would conflict with wickets object creation strategy. 但是我认为这将与检票口对象创建策略冲突。
To answer myself I post the solution, which I found with the help of AtomicGamer Dev Blog . 为了回答自己,我发布了解决方案,该解决方案是在AtomicGamer Dev Blog的帮助下找到的。
Since wicket-guice supports only Guice 1, Guice needs to be excluded from the wicket-guice extension. 由于wicket-guice仅支持Guice 1,因此必须从wicket-guice扩展中排除Guice。

The actual integrations happens in the init
method, which calls the addComponentInstantiationListener
method. 实际的集成发生在init
方法中,该方法调用addComponentInstantiationListener
方法。
import com.google.inject.Guice;
import com.google.inject.Injector;
import org.apache.wicket.Page;
import org.apache.wicket.protocol.http.WebApplication;
import org.apache.wicket.guice.GuiceComponentInjector;
public class NavigatorApplication extends WebApplication {
@Override
public Class<? extends Page> getHomePage() {
return Startpage.class;
}
@Override
protected void init() {
super.init();
Injector injector = Guice.createInjector(new WebAppModule());
addComponentInstantiationListener(
new GuiceComponentInjector(this, injector));
}
}
I have successfully implemented a solution where wicket's configuration and startup are written purely in java code using Guice's ServletModule - no xml used for wicket at all. 我已经成功实现了一个解决方案,其中,使用Guice的ServletModule,仅用Java代码编写了wicket的配置和启动-根本没有xml用于wicket。
All the details are described here in a blog post I've written. 我写的一篇博客文章中介绍了所有详细信息。
Full source (zip/svn) and a working example eclipse project are available for download as well (links are at the end of the post). 完整的源代码(zip / svn)和一个有效的eclipse示例项目也可以下载(链接在文章末尾)。
I think you'll find it great to once again forget about web.xml maintenance :) 我想您会发现再次忘记web.xml维护非常好:)
