dispatcher-servlet.xml：

<context:component-scan base-package="com.cpp"  [b]use-default-filters="false"[/b]> 
	
		<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
	</context:component-scan>

3、如果没有配置<context:component-scan>的use-default-filters属性，则默认为true，在创建ClassPathBeanDefinitionScanner时会根据use-default-filters是否为true来调用代码

默认ClassPathBeanDefinitionScanner会自动注册对@Component、@ManagedBean、@Named注解的Bean进行扫描。如果细心，到此我们就找到问题根源了。

applicationContext.xml：
	<context:component-scan base-package="com.cpp">
	
		<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" />
	</context:component-scan>
