Spring MVC 3中ModelAndView类的功能

Question

This may sound really stupid but I am unable to understand the flow of Spring MVC in my project.

When I write the below mentioned code, what happens?

ModelAndView mav = new ModelAndView("paging");

I have a paging.jsp in my project but what happens, how does it flow?

When you write in your method

    ModelAndView mav = new ModelAndView("paging");
    ...
    return mav;

you tell Spring that you return model and view with the name paging . In configuration you need to tell Spring how to resolve this name. In your case you could use UrlBasedViewResolver :

<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/jsp/"/>
    <property name="suffix" value=".jsp"/>
</bean>
