Spring手动装配之Spring @Enable 模块装配：
1、@Enable注解模块

框架实现	@Enable注解	激活模块
Spring Framework	@EnableWebMvc	Web MVC 模块
Spring Framework	@EnableTransactionManagement	事务管理模块
Spring Framework	@EnableCaching	Caching 模块
Spring Framework	@EnableMBeanExport	JMX 模块
Spring Framework	@EnableAsync	异步处理模块
Spring Framework	@EnableWebFlux	Web Flux 模块
Spring Framework	@EnableAspectJAutoProxy	AspectJ 代理模块
…	…	…
Spring Boot	@EnableAutoConfiguration	自动装配模块
Spring Boot	@EnableManagementContext	Actuator 管理模块
Spring Boot	@EnableConfigurationProperties	配置属性绑定模块
Spring Boot	@EnableOAuth2Sso	OAuth2 单点登录模块
…	…	…
Spring Cloud	@EnableEurekaServer	Eureka服务器模块
Spring Cloud	@EnableConfigServer	配置服务器模块
Spring Cloud	@EnableFeignClients	Feign客户端模块
Spring Cloud	@EnableZuulProxy	服务网关 Zuul 模块
Spring Cloud	@EnableCircuitBreaker	服务熔断模块

2、实现方式
1）注解驱动

@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@Documented@Import(CachingConfigurationSelector.class)
public @interface EnableCaching {
    
    
	// ...
}

2）接口编程

public class CachingConfigurationSelector extends AdviceModeImportSelector<EnableCaching> {
    
    

public String[] selectImports(AdviceModeadviceMode) {
    
    
	switch (adviceMode) {
    
    
		case PROXY:
		return new String[] {
    
     
			AutoProxyRegistrar.class.getName(),ProxyCachingConfiguration.class.getName()
		};
		case ASPECTJ:
		return new String[] {
    
     
			AnnotationConfigUtils.CACHE_ASPECT_CONFIGURATION_CLASS_NAME 
		};
		default:
		return null;    
	}
}
