创建具有多个子上下文的 Spring Boot 应用程序 [英] Create a spring boot application with multiple child contexts

问题描述

我正在尝试使用具有分层应用程序上下文的 Spring Boot 创建应用程序.我目前的主要方法如下:

I'm trying to create an application using spring boot with an hierarchical application context. My current main method looks like:

public static void main(String[] args) {
    new SpringApplicationBuilder(TestApplication.class)
            .child(AuditServiceConfiguration.class).web(true)
            .child(TaskServiceConfiguration.class).web(true)
            .run(args);
}

并且两个子配置被注释为:

and the two children configurations are annotated with:

@EnableAutoConfiguration
@Configuration

这个想法是有一个包含所有公共 bean 的父上下文和每个子上下文来运行自己的 MVC，同时与它的兄弟姐妹隔离.

The idea is to have a parent context containing all common beans and each child context to run its own MVC while being isolated from its siblings.

不幸的是，当我运行上面的代码时，只初始化并启动了最后一个子上下文.

Unfortunately when I run the above, only the last child context is initialised and started.

任何指向正确方向的指针将不胜感激.

Any pointers in the right direction would be greatly appreciated.

问候，

推荐答案

child(...) 方法创建并返回另一个SpringApplicationBuilder>，所以当你调用第二个 child(...) 方法时，你不是在为孩子实例化一个兄弟，而是在第一个孩子上创建一个孩子，这使得父母成为 爷爷.

The child(...) method creates and returns another SpringApplicationBuilder, so when you call that second child(...) method, you are not instantiating a brother for the child, you are making a child on the first child, which makes the parent become a grandpa.

抛开笑话，看看sibling(...) 方法，该方法允许创建具有相同父级的另一个上下文.

Jokes aside, have a look at the sibling(...) method which allows to create another context with the same parent.
