在 json 中獲取 null 響應

Question

我有一個現有項目，我必須在其中添加過濾器“dealername”。 我已經實施了它，但其他值給出的響應為 null。

controller api 我有-

@PostMapping("/getJobcardDetails")
    @ResponseBody
    @LogExecution
    public ResponseEntity<?> getJobcardDetails(@RequestBody  DealerRequest request) {
        try {
            Object response = null;
            response = service.getJobcardDetails(request);
            if (response != null) {
                return new ResponseEntity<>(
                        new Response(Constants.SUCCESS_CODE, Constants.SUCCESS, Constants.DATA_FOUND, response),
                        HttpStatus.OK);
            } else {
                return new ResponseEntity<>(new Response(Constants.SUCCESS_CODE, Constants.SUCCESS,
                        Constants.NO_DATA_FOUND, Constants.SUCCESS), HttpStatus.OK);
            }
        } catch (Exception e) {
            logger.error("Exception in getDistinctValues(): ", e);
            return new ResponseEntity<>(new Response(Constants.ERROR_CODE, Constants.ERROR, Constants.INTERNAL_SERVER,
                    Constants.INTERNAL_SERVER), HttpStatus.INTERNAL_SERVER_ERROR);
        }

    }

我在其中添加了過濾器的服務實現-

public Object getJobcardDetails(DealerRequest request) throws Exception {
        
        String clause = " where jc.dealer_code = dm.code ";
        String AND_CLAUSE = " and ";
        String WHERE_CLAUSE = " where ";
        try {
            if (!TextUtils.isEmpty(request.getCity())) {
                if (!clause.isEmpty()) {
                    clause += AND_CLAUSE;
                } else {
                    clause += WHERE_CLAUSE;
                }
                clause += " dm.city = '" + request.getCity() + "'";
            }
            if (!TextUtils.isEmpty(request.getRegion())) {
                if (!clause.isEmpty()) {
                    clause += AND_CLAUSE;
                } else {
                    clause += WHERE_CLAUSE;
                }
                clause += " dm.region = '" +request.getRegion()+ "'";
            }
            if (!TextUtils.isEmpty(request.getState())) {
                if (!clause.isEmpty()) {
                    clause += AND_CLAUSE;
                } else {
                    clause += WHERE_CLAUSE;
                }
                clause += "dm.state = '" +request.getState()+ "'";
            }
            if (!TextUtils.isEmpty(request.getType())) {
                if (!clause.isEmpty()) {
                    clause += AND_CLAUSE;
                } else {
                    clause += WHERE_CLAUSE;
                }
                clause += " dm.type = '" +request.getType()+ "'";
            }
            if (!TextUtils.isEmpty(request.getJcType())) {
                if (!clause.isEmpty()) {
                    clause += AND_CLAUSE;
                } else {
                    clause += WHERE_CLAUSE;
                }
                clause += " jc.js_type_desc = '" +request.getJcType()+ "'";
            }
            if (!TextUtils.isEmpty(request.getdealername())) {
                if (!clause.isEmpty()) {
                    clause += AND_CLAUSE;
                } else {
                    clause += WHERE_CLAUSE;
                }
                clause += " jc.dealername = '" +request.getdealername()+ "'";
            }
        } catch (Exception e) {
            logger.error("Exception in getDealer Details(): ", e);  
        }
        
        return dao.getJobcardDetails(clause);
    

    }

}

道實現-

@Override
    @Cacheable(value="getJobcardDetails",key = "#clause")
    public Object getJobcardDetails(String clause) throws Exception {
        String sql = QueryConstant.JOBCARD_DETAILS;
        sql = sql.replaceAll("#clause", clause);
        RowMapper<DealerResponse> rowMapper = new BeanPropertyRowMapper<DealerResponse>(DealerResponse.class);
        List<DealerResponse> list= jdbcTemplate.query(sql, rowMapper);
        if (list != null && list.size() > 0) {
            
            return list;
        }
        return null;
    }
    

'查詢常量' class，我在其中編寫了查詢以從表中獲取數據-

public static final String JOBCARD_DETAILS = "select jc.*, dm.lat,dm.lng,l.icon as icon , l.color as color \r\n"
            +   "from jobcarddata jc   left outer join \r\n"
            + "dealer_mst dm on jc.dealer_code = dm.code left outer join    lookup l \r\n"
            + "on  dm.type = l.subcategory  #clause";

json 我正在從請求類中點擊-

{
    "region" :  "",
    "city" : "",
    "state" : "",
    "type" : "",
    "jctype" : "",
    "dealername" : ""


}

響應變得空

Answer 1

我從查詢常量 class 中通過從 dealer master 獲取每一列來解決它——

 "select jc.*, dm.lat,dm.lng,l.icon as icon , l.color as color , dm.name , dm.code , dm.address , dm.pincode , dm.city , dm.state , dm.region , dm.type , dm.contact_number , dm.creation_date , dm.opentime , dm.closetime  \r\n"
            +   "from jobcarddata jc   left outer join"
