关于springmvc的，helloworld一直404！

大家好！我遇到一个很简单的问题，关于springmvc的，helloworld一直404！找了2天了还没解决，帮忙给看看，谢谢！

web.xml

<filter>
  <filter-name>CharacterEncodingFilter</filter-name>
  <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
  <init-param>
    <param-name>encoding</param-name>
    <param-value>UTF-8</param-value>
  </init-param>
  <init-param>
    <param-name>forceResponseEncoding</param-name>
    <param-value>true</param-value>
  </init-param>
</filter>
<filter-mapping>
  <filter-name>CharacterEncodingFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

<servlet>
  <servlet-name>DispatcherServlet</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <init-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:springmvc.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>

springmvc.xml

<!-- 开启注解扫描 -->
<context:component-scan base-package="org.yr.controller"/>

<!-- 配置springmvc的基本控制器，并开启了对json数据格式的支持 -->
<mvc:annotation-driven/>

<!-- 配置springmvc的视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/"/>
    <property name="suffix" value=".html"/>
</bean>

controller
package org.yr.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HelloController {

@RequestMapping("/hello")
public String hello(){
    return "success";
}

}

HelloController 类上面加一个这个 @RequestMapping("/")

@RequestMapping("/")
@Controller
public class HelloController {

    @RequestMapping("/hello")
    public String hello(){
        return "success";
    }
}

spring mvc 的配置加载注意 classpath 后面有个 星号

<!-- Spring MVC 调度员Servlet -->
    <servlet>
        <servlet-name>springMVC</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath*:spring/mvc-config.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springMVC</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

• 这有个类似的问题, 你可以参考下: https://ask.csdn.net/questions/7666045
• 你也可以参考下这篇文章：SpringMVC无web.xml原理

访问地址：localhost:8080/springmvc/hello/1
还是404。。。
