天津做网站哪家好/如何把网站推广

 public void invoke(ComparisonSpotEvaluationResultsExcel comparisonSpotEvaluationResultsExcel, AnalysisContext analysisContext) {/*** 记录行号码*/ReadRowHolder readRowHolder = analysisContext.readRowHolder();Integer rowIndex = readRowHolder.getRowIndex();String row = "第 " + (rowIndex + 1) + " 行,";DetectionIndexServiceImpl.CheckResult error = new DetectionIndexServiceImpl.CheckResult();if (comparisonSpotEvaluationResultsExcel.getTbbh() == null || comparisonSpotEvaluationResultsExcel.getTbbh().equals("")) {error.setTableLocation(row);error.setErrorMessage("图斑编号为空");errors.add(error);}if (comparisonSpotEvaluationResultsExcel.getTbbh2() == null || comparisonSpotEvaluationResultsExcel.getTbbh2().equals("")) {error.setErrorMessage("转换图斑编号为空");error.setTableLocation(row);errors.add(error);}if (comparisonSpotEvaluationResultsExcel.getProvince() == null || comparisonSpotEvaluationResultsExcel.getProvince().equals("")){error.setErrorMessage("省份为空");error.setTableLocation(row);errors.add(error);}if (comparisonSpotEvaluationResultsExcel.getCity() == null || comparisonSpotEvaluationResultsExcel.getCity().equals("")) {error.setErrorMessage("地市为空");error.setTableLocation(row);errors.add(error);}if (comparisonSpotEvaluationResultsExcel.getDistrict() == null || comparisonSpotEvaluationResultsExcel.getDistrict().equals("")) {error.setErrorMessage("区县为空");error.setTableLocation(row);errors.add(error);}if(comparisonSpotEvaluationResultsExcel.getGrade()==null){error.setErrorMessage("矿山（图斑）污染评分等级为空");error.setTableLocation(row);errors.add(error);}ComparisonSpotEvaluationResults results = new ComparisonSpotEvaluationResults();BeanUtil.copyProperties(comparisonSpotEvaluationResultsExcel, results);results.setType(type);// 、、、r.add(results);}

原本想省劲儿只创建一个error，然后将该轮循环收集到错误放到集合里，然后就出现了每一行都是同一个错误提示。后来我又做了个小测试，发现确实会覆盖原来的，推断集合里存的是对象的引用地址。
