Spring Boot: Configuration Class is simply ignored and not loaded
提问by user991710
I have the following @Configurationclass on the classpath of a few of my @SpringBootApplications:
我@Configuration的一些@SpringBootApplications的类路径上有以下类：
@Configuration
@Import({MainConfig.class, RestConfig.class})
public class ApiConfig {
@Bean
@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
public Client client() throws ExecutionException, InterruptedException {
return service.create(Client.class);
}
}
I have two services that use this config (with differently named Clientclasses).
我有两个使用此配置的服务（具有不同命名的Client类）。
Service 1 starts correctly and loads this config. I can see during start up that a bean of type ApiConfigwas eagerly initialized.
服务 1 正确启动并加载此配置。我可以在启动期间看到一个类型的 beanApiConfig被急切地初始化。
Service 2 starts incorrectly: the above configuration class is simply ignored and not initialized.
服务 2 启动不正确：上面的配置类被简单地忽略并且没有初始化。
The services are started in separate JVMs.
这些服务在单独的 JVM 中启动。
Ther services have nearly identical, very small application.propertiesfiles:
这些服务具有几乎相同的非常小的application.properties文件：
spring.application.name=xxx-api
server.port=0
eureka.name=xxx.api
# Only for reading properties from a central location
context.initializer.classes=com.package.contextClass
I'm not even sure what kind of additional information I could write into the question. I have been going through logs for a couple of hours now and see no discernible difference, simply that it plainly ignores my @Configurationclass.
我什至不确定我可以在问题中写入什么样的附加信息。我已经浏览了几个小时的日志，并没有发现明显的区别，只是它显然忽略了我的@Configuration课程。
Has anyone had this issue before?
以前有人遇到过这个问题吗？

The @SpringBootApplication annotation (or, more precisely the inferred @ComponentScan annotation) by default only scans the classpath next to and below the annotated class.
默认情况下，@SpringBootApplication 注释（或更准确地说是推断的 @ComponentScan 注释）仅扫描带注释的类旁边和下方的类路径。
So, your configuration class must be placed next to or in a sub package of you Application class.
因此，您的配置类必须放置在您的 Application 类的子包中或旁边。
