Spring MVC的配置使用（不使用註解）
流程：
1.配置spring MVC開發環境
---引入ioc，webmvc開發包
---src中新增applicationContext.xml配置檔案
2.編寫Controller
public class HelloController implements Controller{
@Override
public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws Exception {
ModelAndView mav = new ModelAndView();
mav.setViewName("hello");
mav.getModel().put("msg", "模型資料");
return mav;
}
}
3.編寫hello.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
</head>
<body>
<%=request.getAttribute("msg") %>
</body>
</html>
4.配置web.xml（配置DispatcherServlet）
<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:applicationContext.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
5.配置applicationContext.xml（配置handlermapping、HelloController、ViewResolver）
<bean id="handlermapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props><prop key="/hello.do">helloController</prop>
</props>
</property>
</bean>
<bean id="helloController" class="controller.HelloController"></bean>
<bean id="viewresolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
