Controller返回类的自动识别，WEB-INF,jsp位置

Controller:

@Controller
@RequestMapping("/params")
public class ParamsController {
    @RequestMapping("/user")
    public ModelAndView getParams(String username,int age) throws Exception{
        ModelAndView mv=new ModelAndView();
        mv.addObject("username",username);
        mv.addObject("age",age);
        mv.setViewName("result");
        return mv;
    }
}

springmvc.xml:

<!-- 视图解释类 -->
<bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/jsp/" />
    <property name="suffix" value=".jsp" />
</bean>

其中视图解释类给出了result后缀.jsp,位置/jsp/中
