sping - Spring注入，在XML配置中引用JavaConfig，结果找不到Config中的bean
XML：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<!--<bean id="sgtPeppers" class="com.soundsystem.SgtPeppers"/>-->
<!--引入JavaConfing配置类-->
<bean class="com.soundsystem.CDConfig"/>
<!--xml配置-->
<bean id="cdPlayer" class="com.soundsystem.CDPlayer">
<constructor-arg ref="sgtPeppers"/>
</bean>
</beans>
sgtPeppers的bean配置在JavaConfig中：
package com.soundsystem;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class CDConfig {
@Bean
public CompactDisc sgtPeppers(){
return new SgtPeppers();
}
}
执行后报错：
警告: Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cdPlayer' defined in class path resource [META-INF/spring/cdplayer-config.xml]: Cannot resolve reference to bean 'sgtPeppers' while setting constructor argument; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'sgtPeppers' available

IDEA显示是绿色的，但是为什么找不到
