分阶段加载spring上下文 [英] Load spring context in phases

问题描述

这是人们会问的那些奇怪的问题之一-为什么?

This is one of those strange questions where people would ask - why?

因此，我将从为何要这样做的原因开始，然后讨论这个问题.我想对如何加载spring上下文有更多的控制.例如，我不想同时加载域和web-api.这将使资源在它们的依赖关系就绪之前可用. 在继续进行此过程之前，可能还需要检查某些事物的状态.可以这么说，模块/上下文之间将存在顺序.也许不仅是在启动，而且还在关机中.

So I will start with why I would like to do this and then go into the issue. I would like to have more control over how the spring context is loaded. For example, I do not want to load the domain and web-api at the same time. That would make the resources available before their dependencies are ready. There might also be that I need to check the state of something before I can continue this process. So to say, there will be sequential order between modules/contexts. Maybe not just booting but also in shutdown.

所以问题是我找不到有关如何加载域上下文的任何信息，然后在完成后我将检查状态并最后加载api上下文.我想从Java代码中完成所有这些操作，因为我需要控制启动流程.我有一些使用SpringServlet加载Web上下文的基础知识.我尚未找到任何信息，是是否有可能加载上下文，等待并加载引用第一个上下文的另一个上下文.

So the issue is that I can't find any information on how to load the domain-context, then when that is finished I would check the state and lastly load the api-context. I would like to do all of this from java-code as I need to control the flow of the start up. I have basics working with SpringServlet loading the web-context. What I have not found any information on is if it is possible to load a context, wait and load another context that refers to the first one.

很高兴知道我没有使用JavaEE或容器.我只在servlet和spring中使用嵌入式Jetty.那么有什么方法可以做到吗?

It might be good to know that I am not using JavaEE nor a container. I am only using embeddded Jetty with servlet and spring. So is there a way this can be done?

推荐答案

考虑延迟加载的bean和延迟代理. 因此，仅在首次使用时才创建Bean ...

Consider lazy loaded beans and Lazy Proxy. So the bean will be created only on first usage ...
