Spring编码不正确

Question

@RequestMapping(value = "getCategoryAspectValues", method = RequestMethod.GET)
    @ResponseBody
    public Map<String, String> retrieveCategoryAspectValues(@RequestParam long cat, @RequestParam String aspectName) {
        return new GetAspectsTask().getAspectValues(cat, (StringUtils.encodeAspectName(aspectName)));       
    }

当请求网址：http://localhost:8080/rpt/getCatValues?cat=55793&aName=US+Shoe+Size+(Women%27s)如下所示时，解码的aspectName值为“US Show Size（Women s）”而不是“US Show Size（Women's）”。如果提供了错误编码的原因，将会很有帮助。
