Spring MVC + Jquery load

@Controller
@RequestMapping("/nvg")
public class NavigationController {
    private Logger logger = LoggerFactory.getLogger(getClass());


    @RequestMapping("/{path}")
    public ModelAndView navigation1(@PathVariable("path") String path) {
        logger.debug("orgEditDialog");
        ModelAndView view = new ModelAndView("org/"+path);
        return view;
    }
}
或者
@RequestMapping("/nvg")
public class NavigationController {
    private Logger logger = LoggerFactory.getLogger(getClass());


    @RequestMapping("/myPageName")//(1)
    public ModelAndView navigation1(@PathVariable("path") String path) {
        logger.debug("orgEditDialog");
        ModelAndView view = new ModelAndView("org/myPageName");
//(2)        return view;
    }
}

不明白，为什么(1)跟(2)一定要一样，才能访问，否则找不到这个model。

    $("#orgHomeIncludeDiv").load("nvg/orgEditDialog", paramters, function (response, status, xhr) {
        if(status!="success"&&status!="notmodified"){
            $.WebUtil.error("无法获取请求的资源.","提示信息");
        }
    });
