需求

在系统迭代的过程中，有一些 Controller 大批量的不再使用，或者有一些接口我们不想再提供给外界

一、使用 @ComponentScan

@SpringBootApplication(scanBasePackages = "com.zrb.excludeSomePkg")
@ComponentScan(basePackages = "com.zrb.excludeSomePkg",// 排除的过滤器excludeFilters = {// 一种是自定义过滤, 一种是按照正则进行过滤@ComponentScan.Filter(type = FilterType.CUSTOM, classes = CustomExcludeFilter.class),@ComponentScan.Filter(type = FilterType.REGEX, pattern = "com.zrb.*.*02")}
)
public class SpringBootAnnoExample {public static void main(String[] args) {ConfigurableApplicationContext applicationContext = SpringApplication.run(SpringBootAnnoExample.class);Pk1Service bean1 = applicationContext.getBean(Pk1Service.class);Pk2Service bean2 = applicationContext.getBean(Pk2Service.class);System.out.println(bean2);System.out.println(bean1);}
}

public class CustomExcludeFilter implements TypeFilter {/*** 忽略pk1包下的所有类*/@Overridepublic boolean match(MetadataReader metadataReader, MetadataReaderFactory metadataReaderFactory) throws IOException {String className = metadataReader.getClassMetadata().getClassName();return className.startsWith("com.zrb.excludeSomePkg.pk1");}
}
