spring MVC是显示层的mvc框架，和struts可以比较；和spring、hibernate没有比较性。
一 、开发流程
1）引jar包
//spring_core spring3.2.9core\commons-logging-1.2.jar spring3.2.9core\spring-beans-3.2.9.RELEASE.jar spring3.2.9core\spring-context-3.2.9.RELEASE.jar spring3.2.9core\spring-core-3.2.9.RELEASE.jar spring3.2.9core\spring-expression-3.2.9.RELEASE.jar //spring mvc springMVC\spring-web-3.2.9.RELEASE.jar springMVC\spring-webmvc-3.2.9.RELEASE.jar
2)web.xml配置spring mvc中核心ervlet:DispatcherServlet
<servlet>
<servlet-name>DispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>
3)编写处理Action类
public class HelloAction implements Controller{ @Override public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception { ModelAndView modelAndView = new ModelAndView(); modelAndView.addObject("word", "nice"); modelAndView.setViewName("/jsp/index.jsp"); return modelAndView; } }
4）在servlet配置文件中进行url和类的映射配置
<?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:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <bean name="/hello.action" class="com.huitong.action.HelloAction"></bean> </beans>
注意：如果之前的配置不正确，则spring会去/WEB-INF/<servlet-name>-servlet.xml查找配置文件。
最后测试，在浏览器中输入地址进行测试。
