java - 使用注解@SpringBootApplication 进行配置

Question

我的 Spring Boot 配置有问题。

我使用 https://start.spring.io/ 创建了基础 Spring Boot 项目

我有一个问题，配置仅适用于子目录中的类:

我尝试过注释@ComponentScan，但没有帮助。

你知道我能用这个做什么吗？

Spring Boot documentation for @SpringBootApplication状态

Many Spring Boot developers always have their main class annotated with @Configuration, @EnableAutoConfiguration and @ComponentScan. Since these annotations are so frequently used together (especially if you follow the best practices above), Spring Boot provides a convenient @SpringBootApplication alternative.

The @SpringBootApplication annotation is equivalent to using @Configuration, @EnableAutoConfiguration and @ComponentScan with their default attributes: [...]

@ComponentScan javadoc 状态

If specific packages are not defined, scanning will occur from the package of the class that declares this annotation.

也就是说，只会扫描与您的 ReadingListApplication 在同一包中的类型。

如果您需要自定义配置，请酌情提供您自己的 @Configuration、@EnableAutoConfiguration 和 @ComponentScan。
