springMvc快速入门
1、创建项目
2、导入jar包
3、配置web.xml文件
<!-- 注册核心控制器 -->
<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>
---------------------------------------------------------------------------------------------------
4、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: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/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
">
<!-- 注册action -->
<bean name="/HelloSpringMVC.action" class="app01.HelloAction"></bean>
</beans>
-----------------------------------------------------------------------------------------------------------------------------------------
5、创建HelloAction.java控制器类
public class HelloAction implements Controller{
/**
* 业务方法
*/
@Override
public ModelAndView handleRequest(HttpServletRequest arg0,
HttpServletResponse arg1) throws Exception {
//ModelAndView表示向视图封装的数据和路径
ModelAndView modelAndView =new ModelAndView();
modelAndView.addObject("result", "我的第一个springMVC程序！！！！");
modelAndView.setViewName("/jsp/success.jsp");
return modelAndView;
}
}
-----------------------------------------------------------------------------------------------------------
6、创建一个前台页面jsp/success.jsp
<body>
<h1>程序调试成功！</h1>
${requestScope.result}<br>
</body>
---------------------------------------------------------------------------------------------------------------------------------------------------
当看到界面是这样的就表示一个案例创建成功了
