        ModelAndView modelAndView = new ModelAndView();
        BmsPress bmsPress = bmsPressService.selectById(id);
        request.setAttribute("bmsPress", bmsPress);

        modelAndView.setViewName("/maintain/bms/press_insert_load");
        return modelAndView;
    }


写法2：

  1. @RequestMapping(value=”press_insert_load/{id}”,method=RequestMethod.GET)   
  2. public String load(@PathVariable(“id”) int id,HttpServletRequest request){   
  3.     BmsPress bmsPress = bmsPressService.selectById(id);   
  4.     request.setAttribute(“bmsPress”, bmsPress);   
  5.     return ”/maintain/bms/press_insert_load”;   
  6. }  
    @RequestMapping(value="press_insert_load/{id}",method=RequestMethod.GET)
    public String load(@PathVariable("id") int id,HttpServletRequest request){
        BmsPress bmsPress = bmsPressService.selectById(id);
        request.setAttribute("bmsPress", bmsPress);
        return "/maintain/bms/press_insert_load";
    }

上面两种写法访问方式都是 ：/maintain/bms/press_insert_load/21

下面这种访问方式：/maintain/bms/press_insert_load.do?id=21
