配置web.xml，放置在WEB-INFO目錄下
<session-config>
<session-timeout>30</session-timeout>

<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
配置springmvc-servlet.xml，放置在WEB-INFO目錄下
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

<!-- 自動搜索@Controller標註的類 -->
<context:component-scan base-package="org.oneDo" />
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />
<!-- Default ViewResolver -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp"></property>
</bean>
<bean id="messageSource"

配置controller函數
//默認將student.do的請求都轉到這個函數來進行處理
@RequestMapping(value="/student.do")
public ModelAndView helloWorld(HttpServletRequest request) {
String idString = request.getParameter("id");
System.out.println("id: " + idString);
request.setAttribute("result", "weichao");
String nameString = request.getParameter("name");
//這個函數執行後會轉到helloWorld.jsp來顯示結果，並將"result"屬性的值置爲map
//這樣在jsp顯示頁面中可以這樣調用：Map map = (Map)request.getAttribute("result")
ModelMap map = new ModelMap();
map.put("one", "one");
map.put("two", "two");
map.put("three", "two");
ModelAndView mAndView = new ModelAndView("helloWorld");
mAndView.addObject("result", map);
mAndView.addObject("answer","weichao");
return mAndView;
}
helloWorld.jsp
<%!Map map;
String answer;
%>
<body>
my name: <%
<!—獲取屬性result的值 -->
map = (Map)request.getAttribute("result");
<!—獲取屬性answer的值 -->
answer = (String)request.getAttribute("answer");
%>
<%=request.getParameterMap().size() %>
<%out.print("<br>" + map.get("two"));
out.print("<br>" + answer);
%>
</body>
