spring的配置文件
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>hello</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>hello</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
设置的为DispatcherServlet继承FrameworkServlet
FrameworkServlet 继承HttpServletBean
HttpServletBean继承httpServlet
springMVCsevlet的配置文件
文件名必须是web.xml配置的servlet的名字-servlet.xml
<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>
<bean name="/welcom.htm" class="com.web.WelcomControl"></bean>
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
SpringMVC默认的Control是BeanNameUrlHandlerMapping以上配置可不用配置
InternalResourceViewResolver配置返回的视图。
prefix+view+suffix 如：/WEB-INF/jsp/welcom.jsp
WelcomControl控制层原始的是继承AbstractController
public class WelcomControl extends AbstractController {
protected ModelAndView handleRequestInternal(HttpServletRequest request,
HttpServletResponse response) throws Exception {
System.out.println("我已经访问到了。。。。");
return new ModelAndView("welcom");
}
}
