spring 3 简单笔记（二）

spring MVC

spring 实现自己的servlet，然后通过注解调用相应的control类。

1. 配置web.xml

    <servlet>
        <servlet-name>spring02</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
         <load-on-startup>1</load-on-startup> 
    </servlet>
    
    <servlet-mapping>
        <servlet-name>spring02</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

2.在web.xml同一目录下配置spring02-servlet.xml

    <context:component-scan base-package="com" />
    <bean id = "viewResolver" class = "org.springframework.web.servlet.view.UrlBasedViewResolver">
        <property name = "viewClass" value = "org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value = "/WEB-INF/view/"/>
        <property name="suffix" value = ".jsp"/>
    </bean> 

3. 实现控制类 SpringController

@Controller
public class SpringController {
    public SpringController(){}
     
    @RequestMapping(value = "/test/{user}")  
     public ModelAndView myMethod(HttpServletRequest request, 
             HttpServletResponse response,     
             @PathVariable("user") String user, 
             ModelMap modelMap) throws Exception{
        
        ModelAndView mv = new ModelAndView();
        mv.setViewName("show"); 
        
        System.out.println("myMethod");
        System.out.println(mv.getViewName());
        
        return mv;     
     }
    
    @RequestMapping(value = "/try.do", method = RequestMethod.GET)  
    public String registPost() {          
    return "show";//返回view/show.jsp
    }  
}
