IDEA下新建SpringMVC项目的配置文件

IDEA新建SpringMVC项目后有三个xml文件，另一个不动，其他两个如下配置，然后应该就可以跑通并正常跳转了。

• web.xml

  <?xml version="1.0" encoding="UTF-8"?>
  <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
          version="4.0">
  
      <listener>
          <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>
  
      <servlet>
          <servlet-name>dispatcher</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>dispatcher</servlet-name>
          <url-pattern>/</url-pattern>
      </servlet-mapping>
  </web-app>
  

• applicationContext.xml

  <?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"
      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">
  
      <context:component-scan base-package="cn.qujialin"/>
  
      <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
          <property name="prefix" value="/"></property>
          <property name="suffix" value=".jsp"></property>
      </bean>
  
  </beans>
  

web.xml报错

'org.springframework.web.servlet.DispatcherServlet' is not assignable to 'javax.servlet.Servlet

解决方法：Project Structure - Modules - 你的项目 - Dependencies,添加Tomcat library
