（不推荐使用）springMVC基本配置+controller层实现Controller接口

<!-- 配置springMVC -->
<servlet>
<servlet-name>springMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<!-- contextConfigLocation 是固定的 -->
<param-name>contextConfigLocation</param-name>
<!-- 配置读取路径-->
<param-value>classpath*:config/spring-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
<servlet-name>springMVC</servlet-name>
<!-- 配置拦截规则-->
<url-pattern>/</url-pattern>
</servlet-mapping>

//实现Controller接口
public class HelloWorld implements Controller {

@Override
public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse arg1) throws Exception {

Map<String,Object> map = new HashMap<String,Object>();
map.put("name", "丽华");

}

}

<div>
<c:forEach items="${map }" var="m">
${m.key } ---- ${m.value }
<br>
</c:forEach>
</div>
