为什么Spring MVC获得404？

我有一个简单的Spring MVC应用程序。我得到了HTTP状态404的报告。帮我解决这个问题。谢谢。为什么Spring MVC获得404？

HTTP状态404 - 找不到

类型状态报告

消息/WEB-INF/users_view.jsp

说明原始服务器没有找到当前表示目标资源或不愿意透露存在。

的Apache Tomcat/9.0.0.M26

我的控制器：

@Controller 
public class UserController { 

    @RequestMapping(value = "/users", method = RequestMethod.GET) 
    public String showUsers(ModelMap model) { 
     return "users_view"; 
    } 
}

项目结构：

我web.xml：

<display-name>User</display-name> 

<context-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value>classpath:applicationContext.xml</param-value> 
</context-param> 

<!-- Creates the Spring Container shared by all Servlets and Filters --> 
<listener> 
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
</listener> 

<!-- Process application servlet --> 
<servlet> 
    <servlet-name>appServlet</servlet-name> 
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 

    <init-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value> 
      classpath:applicationContext.xml 
     </param-value> 
    </init-param> 
    <load-on-startup>1</load-on-startup> 
</servlet> 

<servlet-mapping> 
    <servlet-name>appServlet</servlet-name> 
    <url-pattern>*.do</url-pattern> 
</servlet-mapping>

而且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"> 

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
     <property name="prefix" value="/WEB-INF/"/> 
     <property name="suffix" value=".jsp"/> 
    </bean> 

    <context:component-scan base-package="ru.pravvich" /> 

</beans>
