@AuthPassport 
    @RequestMapping("/OMS315/appr/{qid}/{pid}/{status}/{sn}/{price}") 
    public @ResponseBody String apprBuy(HttpServletRequest request, HttpServletResponse response, 
            @PathVariable("qid") String pvQuotedID, @PathVariable("pid") Long pvProdID, @PathVariable("sn") String pvSN, 
            @PathVariable("price") Double pvPrice, @PathVariable("status") Integer pvStatus) { 
        JSONData lvRet = new JSONData(); 
        try { 
            Map<String,Object> lvParams=getParamsFromRequest(request); 
            String lvRmk=(String) lvParams.get("rmk"); 
            String lvSup=(String) lvParams.get("sup"); 
            ModifyDataException lvErr = module.approveBuy(pvQuotedID, pvProdID, pvSN, pvPrice, pvStatus, 
                    lvSup,lvRmk, 
                    getCurrLogin(request), getLocale(request)); 
            if (lvErr != null) { 
                throw lvErr; 
            } 
            // return JsonUtils.jsonFromObject(lvRet); 
        } catch (Exception e) { 
            BaseModule.jsonDataFillErrMsg(lvRet, e); 
        } 
        return JsonUtils.jsonFromObject(lvRet); 
    }

上述代码中,如果price为小于1的小数,如0.15,则传递给pvPrice的值为0, 查资料, 必须对{price}点位符进行如下修饰:{price:.+}

@AuthPassport 
    @RequestMapping("/OMS315/appr/{qid}/{pid}/{status}/{sn}/{price:.+}") 
    public @ResponseBody String apprBuy(HttpServletRequest request, HttpServletResponse response, 
            @PathVariable("qid") String pvQuotedID, @PathVariable("pid") Long pvProdID, @PathVariable("sn") String pvSN, 
            @PathVariable("price") Double pvPrice, @PathVariable("status") Integer pvStatus) { 
        JSONData lvRet = new JSONData(); 
        try { 
            Map<String,Object> lvParams=getParamsFromRequest(request); 
            String lvRmk=(String) lvParams.get("rmk"); 
            String lvSup=(String) lvParams.get("sup"); 
            ModifyDataException lvErr = module.approveBuy(pvQuotedID, pvProdID, pvSN, pvPrice, pvStatus, 
                    lvSup,lvRmk, 
                    getCurrLogin(request), getLocale(request)); 
            if (lvErr != null) { 
                throw lvErr; 
            } 
            // return JsonUtils.jsonFromObject(lvRet); 
        } catch (Exception e) { 
            BaseModule.jsonDataFillErrMsg(lvRet, e); 
        } 
        return JsonUtils.jsonFromObject(lvRet); 
    }
