springmvc快速入门（XML版本）

1）springmvc快速入门（传统版）

步一：创建springmvc-day01这么一个web应用

步二：导入springioc，springweb , springmvc相关的jar包

步三：在/WEB-INF/下创建web.xml文件

<servlet>
        <servlet-name>DispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>DispatcherServlet</servlet-name>
        <url-pattern>*.action</url-pattern>
    </servlet-mapping>

步四：创建HelloAction.java控制器类

/**
 * 控制器
 */
public class HelloAction implements Controller{
    /**
     * 业务方法
     */
    public ModelAndView handleRequest(HttpServletRequest requqest,HttpServletResponse response) throws Exception {
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.addObject("message","这是我的第一个springmvc应用程序");
        modelAndView.setViewName("/jsp/success.jsp");
        return modelAndView;
    }
}

步五：在/WebRoot/下创建jsp/success.jsp

<%@ page language="java" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <title>这是我的第一个springmvc应用程序</title>
  </head>
  <body>
    success.jsp<br/>
    ${message}
  </body>
</html>

步六：在/WEB-INF/创建DispatcherServlet-servlet.xml配置文件，xml头部信息与spring.xml相同

注意：该配置文件的命名规则：web.xml文件中配置的<servlet-name>的值-servlet.xml

?xml version="1.0" encoding="UTF-8"?>
<beans 
      xmlns="http://www.springframework.org/schema/beans"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xmlns:context="http://www.springframework.org/schema/context"
      xmlns:aop="http://www.springframework.org/schema/aop"
      xmlns:tx="http://www.springframework.org/schema/tx"
      xmlns:mvc="http://www.springframework.org/schema/mvc"
      xsi:schemaLocation="
      
      http://www.springframework.org/schema/beans 
      http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
      
      http://www.springframework.org/schema/context
      http://www.springframework.org/schema/context/spring-context-3.0.xsd
       
      http://www.springframework.org/schema/aop 
      http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
      
      http://www.springframework.org/schema/tx
      http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
    
      http://www.springframework.org/schema/mvc
      http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
        
      ">
      
      
    
    <!-- 控制器(程序员) -->
    <bean name="/hello.action" class="loaderman.javaee.springmvc.base.HelloAction"></bean>  
    
    
    <!-- 映射器(框架) -->  
    <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>  
      
      
    <!-- 适配器(框架) -->  
    <bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>  
      
      
    <!-- 视图解析器(框架) -->  
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"></bean>  
      
      
</beans>

步七：部署web应用到tomcat中，通过浏览器访问helloaction的URL
