在web.xml里面添加DispatcherServlet
<servlet>
<servlet-name>springmvc
</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<init-param>
<param-name>contextConfigLocation
</param-name>
<param-value>classpath:springmvc-servlet.xml
</param-value>
</init-param>
<load-on-startup>1
</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc
</servlet-name>
<url-pattern>*.do
</url-pattern>
</servlet-mapping>
过滤 *.do
对应路径下增加springmvc-servlet.xml文件
这里对应路径 < param-value >classpath:springmvc-servlet.xml</ param-value >

</bean>
<bean id="mvcController" class="controller.MvcController"/>
</beans>
< prop key="/mvc_test.do">mvcController</ prop > key中的访问路径会使用id=mvcController的类 就是这个< bean id=“mvcController” class=“controller.MvcController”/>
Controller接口
package controller

import org

public class MvcController implements Controller {
public ModelAndView
handleRequest(HttpServletRequest request
, HttpServletResponse response
){
ModelAndView mav
=new ModelAndView("mvc_test.jsp");
mav
.addObject("message","SpringMVC is work!!");
return mav
;
}
}
视图是 mvc_test.jsp 模型数据 mav.addObject(“message”,“SpringMVC is work!!”);
mvc_test.jsp
