ComponentScan注解用于指定扫描的路径，可以通过excludeFilters，includeFilters分别排除或包含部分组件

1、excludeFilters

package spring.example.anno;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.FilterType;
import org.springframework.stereotype.Service;

@Configuration
@ComponentScan(value = {"spring.example.anno.user", "spring.example.anno.item"},
excludeFilters = {@ComponentScan.Filter(type = FilterType.ANNOTATION,value = {Service.class})})
public class Config {
}

输出结果：

config
userController
userDao
itemController
itemDao

@ComponentScan.Filter  type属性用于指定过滤时使用的类型，包括以下几种

FilterType.ANNOTATION ：注解类型

FilterType.ASSIGNABLE_TYPE：具体的类

FilterType.ASPECTJ

FilterType.REGEX

FilterType.CUSTOM
