mvc:annotation-driven

<mvc:annotation-driven /> ：確定呼叫哪個controller的哪個方法來處理當前請求。如果沒有回找不到@RequestMapping指定的路徑
 
 

context:annotation-config

掃描的註解如下：@Autowired，@Resource 、@PostConstruct、@PreDestroy，@PersistenceContext，@Required。
 
 

context:component-scan

<context:annotation-config />：context:component-scan做了context:annotation-config要做的事情，還額外支援@Component，@Repository，@Service， @Controller @RestController, @ControllerAdvice, and @Configuration 註解。
所以配置context:component-scan就不需要配置context:annotation- config/
 
use-default-filters=“false”，不使用預設過濾器（所有包都不自動掃描），需要<context:include-filter type=“annotation” expression=“org.springframework.stereotype.Controller”，指定只掃描的包。

     <context:component-scan base-package="test.*.controller" use-default-filters="false">        
            <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>     
            <context:include-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/> 
     </context:component-scan>
 

<context:exclude-filter type=“annotation” expression=“org.springframework.stereotype.Controller”/>，全部包都掃描，除了標籤裡面配置的。

      <context:component-scan base-package="test.*">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
        <context:exclude-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/>
      </context:component-scan>
