关于@ComponentScan TypeFilter自定义指定扫描bean的规则

@Configuration
@ComponentScan(value = "com.wjy",useDefaultFilters = false,includeFilters = {
		@Filter(type = FilterType.CUSTOM,value = {MyFilterType.class})
})
public class Config {
	public static void main(String[] args) {
		var annotationConfigApplicationContext = new AnnotationConfigApplicationContext(Config.class);
		var beanNames = annotationConfigApplicationContext.getBeanDefinitionNames();
		//打印所有的扫描到的bean
		Arrays.stream(beanNames).forEach(e -> System.out.println(e));
	}
}

public class MyFilterType implements TypeFilter {
	/**
	 *
	 * @param metadataReader 读取到的当前正在扫描的信息
	 * @param metadataReaderFactory 可以获取到其他任何类的信息的
	 * @return
	 * @throws IOException
	 */
	@Override
	public boolean match(MetadataReader metadataReader, MetadataReaderFactory metadataReaderFactory) throws IOException {
		//获取当前类注解信息
		var annotationMetadata = metadataReader.getAnnotationMetadata();
		//获取当前正在扫描类信息
		var classMetadata = metadataReader.getClassMetadata();
		//获取当前类路径
		var resource = metadataReader.getResource();
		if(annotationMetadata.getClassName().toLowerCase().contains("service")){
			return true;
		}
		return false;
	}
