spring - @SpringBootConfiguration 和 @Configuration 有什么区别？

Question

@SpringBootConfiguration 和 @Configuration 有什么区别？我找不到关于它的太多细节。

Answer 1

根据 Spring Boot Document (hierarchy below)，我们可以说 @Configuration 是 @SpringBootConfiguration 的一部分，最终有 @SpringBootApplication

@SpringBootApplication
-------> @SpringBootConfiguration
       -------> @Configuration

@SpringBootApplication

Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Inherited
@SpringBootConfiguration
@EnableAutoConfiguration
@ComponentScan(excludeFilters = {
        @Filter(type = FilterType.CUSTOM, classes = TypeExcludeFilter.class),
        @Filter(type = FilterType.CUSTOM,
                classes = AutoConfigurationExcludeFilter.class) })
public @interface SpringBootApplication {
...}

@SpringBootConfiguration

@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Configuration
public @interface SpringBootConfiguration {

}

@配置

    @Target(ElementType.TYPE)
    @Retention(RetentionPolicy.RUNTIME)
    @Documented
    @Component
    public @interface Configuration {
}
