springboot项目中@PathVariable中get请求中有|报400错误

http://localhost:9105/publishTheme/ST0821122|461

后端直接改成这种也没用，除非前端也得做加码才可以

@GetMapping("/{id}")     public Object getPublishTheme(@PathVariable String id) {         Map params= new HashMap();         String decodeId="";         try {             decodeId=URLDecoder.decode(id,"UTF-8");         } catch (UnsupportedEncodingException e) {             logger.error(e.getMessage(), e);         }         params.put("ID",decodeId);         return publishThemeService.getPublishTheme(params);     }
