本文介绍了如何在引导后注入会话/用户对象?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 有些例子中,不同类型的对象被注入演示者,但我找不到解释如何做到这一点。 在 Bootstrap-Code 例如他们正在注入例如一个 SecurityDelegate 对象。 同样在网守例如我看到注入的东西,例如 MyGatekeeper ,但这是怎么完成的? 我想要先检查用户是否登录,然后创建一个 CurrentSession 对象或类似的东西。但我怎样才能通过/注入这个对象? 目前我正在初始化一个单例对象 CurrentUser which是一种丑陋的imho。我希望获得GWTP支持,但如何? 以 CurrentSession 被注入关守: $ b @DefaultGatekeeper public class LoggedInGatekeeper实现Gatekeeper { private final CurrentSession currentSession; @Inject LoggedInGatekeeper(CurrentSession currentSession){ this.currentSession = currentSession; @Override public boolean canReveal(){ return currentSession.isLoggedIn(); $ b $ p $如何注入 CurrentSession 在这里? 解决方案下面是一个教程,介绍如何使用Gatekeeper: http://dev.arcbees.com/gwtp/tutorials/tutorial-part2.html 在你的杜松子酒模块中声明CurrentSession的类(本教程中的CurrentUser)为Singleton,如下所示: public class YourGinModule extends AbstractGinModule { @Override protected void configure(){ bind(CurrentSession.class).in(Singleton.class); ... } } 在这里你可以找到另一个例子,在客户端使用GWTP Gatekeeper,在服务器端使用Spring Security: https:// github.com/imrabti/gwtp-spring-security There are examples where different kinds of objects are getting injected into a presenter, but I can't find an explanation how this can be done.In the Bootstrap-Code example they are injecting e.g. a SecurityDelegate object. Also in the Gatekeeper example I see things being injected, e.g. MyGatekeeper, but how is this done?What I want is to first check if the user is logged in and then create a CurrentSession object or something like this. But how can I pass/inject this object around?At the moment I am initializing a singleton object CurrentUser which is kind of ugly imho. I would like to get the GWTP support running, but how?Take this example of the CurrentSession being injected into the gatekeeper:@DefaultGatekeeperpublic class LoggedInGatekeeper implements Gatekeeper { private final CurrentSession currentSession; @Inject LoggedInGatekeeper(CurrentSession currentSession) { this.currentSession = currentSession; } @Override public boolean canReveal() { return currentSession.isLoggedIn(); }}How do I inject CurrentSession here? 解决方案 Here is a tutorial that explains how to use Gatekeeper : http://dev.arcbees.com/gwtp/tutorials/tutorial-part2.htmlDeclare CurrentSession's class ( CurrentUser in the tutorial ) as Singleton in your Gin's module like below :public class YourGinModule extends AbstractGinModule { @Override protected void configure() { bind( CurrentSession.class ).in ( Singleton.class ); ... }}Here you can find another example using GWTP Gatekeeper on client side and Spring Security on server side : https://github.com/imrabti/gwtp-spring-security 这篇关于如何在引导后注入会话/用户对象?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
