问题描述
我正在尝试设置 Netty 以在我的Web应用程序中嵌入运行.
I'm trying to setup Netty to run embedded in my web application.
我找到了以下文档: http://docs.jboss.org/netty/3.2/api/org/jboss/netty/channel/socket/http/package-summary.html#package_description 描述了如何配置一个启动Netty servlet的web.xml文件.
I have found the following document: http://docs.jboss.org/netty/3.2/api/org/jboss/netty/channel/socket/http/package-summary.html#package_description that describes how to configure a web.xml file that starts a Netty servlet.
现在文档显示:
这听起来很合理，但我不清楚实际上-应该如何工作.假设我要使用Spring作为Ioc容器，将netty绑定到本地传输的正确bean配置是什么?
That sound reasonable but it is not clear to me how - practically - that should work. Say that I want to use Spring as Ioc container, what would be the proper beans configuration to bind netty to the local transport?
此外，如何启动Spring上下文?来自web.xml?
Also, how do I start the Spring context? From web.xml?
谢谢
推荐答案
我个人建议使用spring.它可以与几乎所有的阳光融为一体.
I personally recommend using spring. It can integrate with almost everything under the sun.
看看下面的链接其中显示了如何将Netty服务器配置为spring bean，然后在Web应用程序中使用它.
Take a look at the following link which shows how to configure your Netty server as a spring bean and then using it in a web app.
这是您可以在Spring + Web应用程序中实现的方法.
This is the way you could do it for a spring + web app.
1) Create relevant spring beans for the server, pipeline factory etc.
2) In the web.xml configure the spring dispatcher servlet.
注意:上面的配置用于在Web应用程序的某个端口上运行Netty服务器.
Note: The above configuration is for running the Netty server at some port along with your web app.
基本上，您可以在任何bean上调用spring bean的init-method属性来启动Netty服务器
Basically you can call the spring bean init-method attribute on any bean to do the netty server startup
您可以按照您的帖子中的链接中所述配置servlet.您可以交叉引用servlet bean中的任何spring bean(例如netty服务器bean)，或在servlet bean的init-method中调用它.
You could configure the servlet as mentioned in the link in your post. You can cross-reference any spring bean(say the netty server bean) within the servlet bean, or call it within your servlet bean's init-method.
另一种可能性是，您可以侦听spring应用程序事件，然后在容器启动后，可以手动启动servlet/netty服务器.
Yet another possibility is that you can listen to spring application events and then after the container has started up, you can manually launch your servlet/netty server.
如果您使用的是grails应用程序，则可以使用bootstrap类(在应用程序启动时调用的便捷类)来在Web应用程序启动时启动Netty服务器
If you are using a grails app then the bootstrap class ( a convenience class which is called on application startup) can be used to startup the Netty server on web app startup
Spring提供了n种方法来满足您的要求，您可以根据自己的方便进行选择.
Spring provides n-number of ways to do what you require, you can choose based on your convenience.
