1.过滤组件 - 包含

dao 层

package com.h3.customer.dao;

public class customerdao 
{
	@override
	public string tostring() {
		return "hello , this is customerdao";
	}	
}

service 层

package com.h3.customer.services;

import org.springframework.beans.factory.annotation.autowired;
import com.h3.customer.dao.customerdao;

public class customerservice 
{
	@autowired
	customerdao customerdao;

	@override
	public string tostring() {
		return "customerservice [customerdao=" + customerdao + "]";
	}
		
}

spring 过滤

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemalocation="http://www.springframework.org/schema/beans
	http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
	http://www.springframework.org/schema/context
	http://www.springframework.org/schema/context/spring-context-2.5.xsd">

	<context:component-scan base-package="com.h3" >

		<context:include-filter type="regex" 
                       expression="com.h3.customer.dao.*dao.*" />

		<context:include-filter type="regex" 
                       expression="com.h3.customer.services.*service.*" />

	</context:component-scan>

</beans>

执行

package com.h3.common;

import org.springframework.context.applicationcontext;
import org.springframework.context.support.classpathxmlapplicationcontext;

import com.h3.customer.services.customerservice;

public class app 
{
    public static void main( string[] args )
    {
    	applicationcontext context = 
		new classpathxmlapplicationcontext(new string[] {"spring-autoscan.xml"});

    	customerservice cust = (customerservice)context.getbean("customerservice");
    	system.out.println(cust);
    	
    }
}

输出

customerservice [customerdao=hello , this is customerdao]

2.过滤组件 - 不包含

<context:component-scan base-package="com.h3.customer" >
		<context:exclude-filter type="annotation" 
			expression="org.springframework.stereotype.service" />		
	</context:component-scan>

<context:component-scan base-package="com.h3" >
		<context:exclude-filter type="regex" 
			expression="com.h3.customer.dao.*dao.*" />		
	</context:component-scan>
