spring和springmvc中,Configuration注解Bean重复加载

问题:bean重复加载
1.如下代码所示,开启Configuration注解,实现Bean代码注入,发现bean重复加载

@Configuration
public class EhCacheConfig {
    
    @Bean(name="cacheManagerFactoryBean")
    public EhCacheManagerFactoryBean ehCacheManagerFactoryBean(){
        EhCacheManagerFactoryBean cacheManagerFactoryBean = new EhCacheManagerFactoryBean();
        cacheManagerFactoryBean.setConfigLocation(new ClassPathResource("ehcache.xml"));
        cacheManagerFactoryBean.setShared (true);
        return cacheManagerFactoryBean;
    }
    
    @Bean(name="ehCacheFactoryBean")
    public EhCacheFactoryBean ehCacheFactoryBean(){
        EhCacheFactoryBean ehCacheFactoryBean = new EhCacheFactoryBean();
        ehCacheFactoryBean.setCacheManager(ehCacheManagerFactoryBean().getObject());
        ehCacheFactoryBean.setCacheName("accountCacheName");
        return ehCacheFactoryBean;
    }
    
    @Bean(name="cache")
    public Cache cache(){
        EhCacheCache cache = new EhCacheCache(ehCacheFactoryBean().getObject());
        return cache;
    }
}

2.spring.xml扫描配置

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

  


3.spring-mvc扫描配置

	<context:component-scan base-package="com.bsoft.platform" use-default-filters="true">
		<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
	</context:component-scan>

  



4.解决:
在spring-mvc上加上exclude-filter,排除不需要扫描的注解,代码如下所示

<context:component-scan base-package="com.bsoft.platform" use-default-filters="true">
		<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
		<context:exclude-filter type="annotation" expression="org.springframework.context.annotation.Configuration" />
</context:component-scan>

或者这样排除springmvc不需要扫描的类
<context:exclude-filter type="regex" expression="com.bsoft.platform..*Config" />
