如何配置Spring MVC的DispatcherServlet？

配置Spring MVC的DispatcherServlet需要以下步骤： 1. 在web.xml文件中配置DispatcherServlet： ```xml <servlet> <servlet-name>dispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/applicationContext.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> ``` 2. 创建一个名为`applicationContext.xml`的Spring配置文件，并在其中配置Spring MVC相关的组件和属性。例如，可以配置扫描包、视图解析器、处理器映射等： ```xml <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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <!-- 扫描包 --> <context:component-scan base-package="com.example.controller" /> <!-- 视图解析器 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/views/" /> <property name="suffix" value=".jsp" /> </bean> <!-- 处理器映射 --> <mvc:annotation-driven /> </beans> ``` 3. 在`applicationContext.xml`中配置其他需要的组件，例如数据源、事务管理器等。 以上是配置Spring MVC的DispatcherServlet的基本步骤。
