Spring Boot @PostMapping 处理异常：使用 try-catch 块

@PostMapping({"/startArchive3"}) public JsonResult startArchive3(String workId ){ try { Map<String,String> params = new HashMap<>(); params.put("传数据工号",workId); organizationClient.addBasicLog(params); JsonResult handoverBasic = organizationClient.getHandoverBasicByNameOrWorkId(workId); List data1 = (List) handoverBasic.getData(); Map data2=null; if (data1.size()>0){ data2 = (Map) data1.get(0); } String instId = data2.get("instId").toString(); String interView = data2.get("leaveInterviewId").toString();

    List<BpmInstData> bpmInstDatas = bpmInstDataService.getByInstId(instId);
    Map<String,Object> params2 = new HashMap<>();

    Map<String,Object> params3 = new HashMap<>();

    if(bpmInstDatas.isEmpty()){
        //自定义表单为空，暂传空数据
        JsonResult jsonResult = new JsonResult(200);
        return jsonResult.setData(new BpmView());
    }
    BpmInstData bpmInstData = bpmInstDatas.get(0);
