原始版构建方式

  1. alt+insert添加依赖，引入spring-webmvc依赖

  2. open moudle setting 配置web中的web Resource Directories路径和Deployment Descriptos路径

  3. 创建任意controller

  4. 于resources文件夹中创建applicationContext.xml和spring-servlet.xml

  5. applicationContext.xml配置，先配置需要扫描的包

           xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

        <!-- base-package 表示要扫描的包；use-default-filters表示使用默认的过滤器，true表示全扫-->
        <context:component-scan base-package="org.ll" use-default-filters="true">
            <!--除去controller，其他的都扫-->
            <context:exclude-filter type="annotation" experssion="org.springframework.stereotype.Controller"/>
        </context:component-scan>

        <!--下面可配mybatis-->
    </beans>

        <!--不使用默认的过滤器，需要指定扫描的包-->
        <context:component-scan base-package="org.ll" user-default-filters="false">
            <!--包括哪个，即指定哪个包-->
            <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
        </context:component-scan>

        <mvc:annotation-driven/>
        <!--视图解析器等在下面配-->
    </beans>
