context:include-filter标签的type属性解析

本文深入解析了Spring框架中自动组件扫描配置的<context:include-filter>标签的type属性,包括annotation、assignable、aspectj、regex和custom五种类型的意义与使用场景。

 Spring容器配置中,自动组件扫描配置中<context:include-filter>标签的type属性解析

<context:component-scan base-package="com.test">
		<context:include-filter type="annotation"
			expression="org.springframework.stereotype.Controller" />
</context:component-scan>

其中type有annotation,aspectj,assignable,custom,regex几种类型。

其意义如下: 

 

annotation:注解类型
assignable_type:annotation:指定的类型
aspectj:按照Aspectj的表达式,基本上不会用到
regex:按照正则表达式
custom:自定义规则
