1.目标实现Spring MVC :
Hello World!
2.工程创建步骤
new : Dynamic Web Project
lib引入Spring框架libs/*.jar
touch web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <servlet> <servlet-name>springMVC</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/config/springMVC-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
touch config/springMVC-servlet.xml
<?xml version="1.0" encoding="UTF-8"?> <beans:beans xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:p="http://www.springframework.org/schema/p" 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 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd" > <context:component-scan base-package="www.xi.com" /> <mvc:annotation-driven /> <beans:bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <beans:property name="prefix" value="/WEB-INF/jsp/" /> <beans:property name="suffix" value=".jsp" /> </beans:bean> </beans:beans>
touch jsp/hello.jsp
文件名称很重要！
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> "hello world" </body> </html>
touch www.xi.com.mvcController.java
package www.xi.com; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; @Controller public class mvcController { private static final Log logger = LogFactory.getLog(mvcController.class); @RequestMapping("/hello") public String hello() { logger.info("hello called"); return "hello"; } }
执行访问：
http://localhost:8080/SpringMVC/hello
显示：
“hello world”
3.问题
1.Spring MVC常用注解有哪些？
2.Spring MVC的基本流程是什么？
3.接口解释
DispatcherServlet
WebApplicationContext
HandlerMapping
HandlerAdapter
Controllers
ViewResolver
LocaleResolver & LocaleContextResolver
HandlerExceptionResolver
ThemeResolver
MultipartResolver
FlashMapManager
4.Servlet,JSP基础概念
5.xml中如何知道有哪些标签，以及标签的意义等？
