package controller;

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

@Controller
@RequestMapping("/mvc")

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

然后配置applicationContext.xml、dispatcher-servlet.xml、web.xml

applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <context:component-scan base-package="controller"/><!--扫描的包 你自己新建的包名-->
</beans>

dispatcher-servlet.xml

    <!--此文件负责整个mvc中的配置-->

    <!--启用spring的一些annotation -->
    <context:annotation-config/>

    <!-- 配置注解驱动 可以将request参数与绑定到controller参数上 -->

    <!--静态资源映射-->
    <!--本项目把静态资源放在了webapp的statics目录下，资源映射如下-->
    <mvc:resources mapping="/css/**" location="/WEB-INF/statics/css/"/>
    <mvc:resources mapping="/js/**" location="/WEB-INF/statics/js/"/>
    <mvc:resources mapping="/image/**" location="/WEB-INF/statics/image/"/>

    <!-- 对模型视图名称的解析，即在模型视图名称添加前后缀(如果最后一个还是表示文件夹,则最后的斜杠不要漏了) 使用JSP-->
    <!-- 默认的视图解析器 在上边的解析错误时使用 (默认使用html)- -->
    <bean id="defaultViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>-->

    </bean>

    <!-- 自动扫描装配 -->
    <context:component-scan base-package="controller"/>
</beans>

web.xml

    <!--welcome pages-->
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

    <!--配置springmvc DispatcherServlet-->
