旁邊的人很煩的,敲着桌子很難受,影響我學習
我決定寫一個模塊
用springmvc
比如增加
其實用來maven以後就不需要再關注這些配置了
這些配置都可以和容易的看出來
第五章 springmvc快速入門(XML版本)
1)springmvc快速入門(傳統版)
步一:創建springmvc-day01這麼一個web應用
步二:導入springioc,springweb , springmvc相關的jar包
步三:在/WEB-INF/下創建web.xml文件
<!-- 註冊springmvc框架核心控制器 --> <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> |
步四:創建HelloAction.java控制器類
/** * 控制器 * @author AdminTC */ public class HelloAction implements Controller{ /** * 業務方法 */ public ModelAndView handleRequest(HttpServletRequest requqest,HttpServletResponse response) throws Exception { ModelAndView modelAndView = new ModelAndView(); modelAndView.addObject("message","這是我的第一個springmvc應用程序"); modelAndView.setViewName("/jsp/success.jsp"); return modelAndView; } } |
步五:在/WebRoot/下創建jsp/success.jsp
<%@ page language="java" pageEncoding="UTF-8"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>這是我的第一個springmvc應用程序</title> </head> <body> success.jsp<br/> ${message} </body> </html> |
步六:在/WEB-INF/創建DispatcherServlet-servlet.xml配置文件,xml頭部信息與spring.xml相同
注意:該配置文件的命名規則: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(程序員) --> <bean name="/hello.action" class="cn.itcast.javaee.springmvc.base.HelloAction"></bean>
<!-- 映射器(框架) --> <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>
<!-- 適配器(框架) --> <bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>
<!-- 視圖解析器(框架) --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"></bean>
</beans> |
步七:部署web應用到tomcat中,通過瀏覽器訪問如下URL:
http://127.0.0.1:8080/springmvc-day01/hello.action
