## 1. 配置web.xml ##

<servlet>
            <servlet-name>springDispatcherServlet</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>springDispatcherServlet</servlet-name>
            
            <url-pattern>/</url-pattern>
        </servlet-mapping>

**不需要定位：只要将配置文件改为 “DispatcherServlet名-servlet.xml”**

就可以使用。

## 2. 配置springmvc配置文件:"springmvc-servlet.xml" ##

<context:component-scan base-package="top.belmode" />
    
        
        <bean
            class="org.springframework.web.servlet.view.InternalResourceViewResolver"
            p:prefix="/WEB-INF/jsp/" p:suffix=".jsp" />
    
        <mvc:annotation-driven />
        <mvc:resources mapping="/WEB-INF/" location="/WEB-INF/" />

## 3. 配置web.xml，让html支持PUT，DELETE ##

前台只要给form表单以POST方式添加一个隐藏项
