Spring XML配置混合Java配置

Question

I have created a basic Spring MVC app, when I config xml like this

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"

       xsi:schemaLocation="http://www.springframework.org/schema/beans 
                            http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
                            http://www.springframework.org/schema/context
                            http://www.springframework.org/schema/context/spring-context-4.3.xsd
                            http://www.springframework.org/schema/mvc
                            http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
" >
    <context:component-scan base-package="com.hell"/>
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/pages/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

everything goes well, the controller and the view mapped via @RequestMapping, but when I add this empty class and build

@Configuration
public class Config {
}

the routing does not work, it say 404 error. then I must add <mvc:annotation-config/> or @EnableWebMVC , the routing then works.
can someone explain this, I think this is so weird.
edit: this is my web.xml to config DispatcherServlet

<servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

Answer 1

我已经搜索了Internet，发现context:component-scan告诉Spring扫描@Configuration类，所以也许这是我的问题的答案，任何人都请纠正我。

Answer 2

@Configuration用于基于Java的spring配置，所以我认为，如果您正在通过Java代码对bean进行配置，则您的xml配置受到限制。我建议您坚持一种方法，这将使您的代码易于维护。
