坑爹的Spring

没有实现类！！！！
@Component实现类的头上没有注解！！！！


例子2：

 Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [com.jingwei.card.passport.home.MainAccountHome] is defined: expected single bean but found 2

问题原因：
在core包中：
<context:component-scan name-generator="com.jingwei.core.spring.BeanNameGenerator" base-package="com.jingwei.card.passport.component"></context:component-scan>
	<context:component-scan name-generator="com.jingwei.core.spring.BeanNameGenerator" base-package="com.jingwei.card.passport.home"></context:component-scan>

而在web工程中
<context:component-scan base-package="com.jingwei" />

结论：
这个类被扫了两遍，所以在getInstant的时候，会找到两个

解决：
web工程或者其他工程中，应该尽量扫描自己的目录
<context:component-scan base-package="com.jingwei.cardverify" />
