/**

public class MyTypeFilter implements TypeFilter {

	@Override
	public boolean match(MetadataReader metadataReader, MetadataReaderFactory metadataReaderFactory)
			throws IOException {
		// 获取当前正在扫描类的注解
		AnnotationMetadata annotationMetadata = metadataReader.getAnnotationMetadata();
		String[] interfaceNames = annotationMetadata.getInterfaceNames();
		for (String name : interfaceNames) {
			System.out.println("---->----   " +name);
		}
//		获取当前正在扫描类的类信息
		ClassMetadata classMetadata = metadataReader.getClassMetadata();
//		获取当前类资源路径
		Resource resource = metadataReader.getResource();
		
		String className = classMetadata.getClassName();
//		设定过滤规则包含Controller
		if(className.contains("Controller")) {
			return true;
		}
		System.out.println("---->   " + className);
		return false;
	}

}

// 配置类标识
@Configuration
//设置扫描包相当于配置文件中<context:component-san ></context:component-san >
@ComponentScan(value = "com.at",includeFilters={
//		@Filter(type=FilterType.ANNOTATION,classes= {Controller.class}),
		@Filter(type=FilterType.CUSTOM,classes= {MyTypeFilter.class})//配置类中增加过滤规则
},useDefaultFilters = false)
public class MainAnnotation{
//	bean注解注入对象
	@Bean
	public Person person() {
		return new Person("王五", "20");
	}
}

注：这里如果是springBoot框架在启动类中增加过滤规则
