如何从单独的 Jars 加载 @Configuration 类 [英] How to load @Configuration classes from separate Jars

问题描述

我有一个 SpringBoot 主应用程序，以及一个单独的 Maven 模块项目，它编译为单独的 Jar.该模块有一个用 @Configuration 注释的 Spring 配置类，我想在主应用程序加载时加载它.

I have a SpringBoot main application, as well as a separate Maven module project that compiles as a separate Jar. The module has a Spring config class annotated with @Configuration, which I want to get loaded, when the main app loads.

显然，这不是开箱即用的(只需将模块包含到主应用程序中).我还需要做什么才能让模块配置类也被主应用程序加载?

Apparently, this does not happen out of the box (by just including the module to the main app). What else do I need to do, to get the module configuration class also get loaded by the main app?

推荐答案

最简单的方法就是扫描@Configuration类所在的包.

The easiest way is to scan the package that the @Configuration class is in.

@ComponentScan("com.acme.otherJar.config")

或者只是将其作为 spring bean 加载:

or to just load it as a spring bean:

 @Bean
 public MyConfig myConfig() {
     MyConfig myConfig = new MyConfig ();
     return myConfig;
 }

其中 MyConfig 类似于:

Where MyConfig is something like:

 @Configuration
 public class MyConfig {
     // various @Bean definitions ...
 }
